The EE-QUARRY project emerges from the necessity to control a very demanding energy-intensive industry, which characterizes from its high energy demands and enormous CO2 emissions. The goal is to improve energy efficiency and to reduce CO2 on quarries, through the develop of a new and highly effective modeling and monitoring Energy Management System technique. The use of crushed stone could increase at a quicker rate than any other major material use. Given the market size, ample resources and stable growth potential of this industry, the understanding and dissemination of energy efficiency opportunities is paramount for European energy efficiency goals. Further, since there are literally several thousands facilities throughout Europe, there is a huge opportunity for replicability of identified energy efficiency measures. This project will first review the stone mining and crushing production processes. It is also important to show that energy use is focused in rock blasting, shot-rock transportation, rock crushing, conveying and screening. As such, standard building energy efficiency measures such as lighting retrofits and support system optimization have small impacts on overall plant energy use. The identification of energy opportunities thus relies heavily on systems optimization. System optimization not only encourages energy efficiency, but typically benefits production as well. Coupled with productivity improvements, the economic incentives for energy efficiency measures in this industry have the magnitude and quick payback that could facilitate industry-wide replication. Once the whole extracting industry process is over, and the quarry plant arrives to the end of its life cycle, many CO2 neutralizing activities will take place. The goal is to generate EE opportunities and CO2 compensation activities due to the environmental impact created in its life time cycle.

SUSTAMINING project marks the start of a series of development activities aiming to realise the concept of an invisible, zero-impact mine. The natural stone extractive sector, still seen as being old-fashioned and highly environment polluting, will join forces to revise this image showing that natural stone extraction can be approached with a cutting edge methodology with low impact underground and zero impact above ground. Faced with this problem this project aims to develop technological support for the sector covering both research centers with expertise in natural stone, business associations and SMEs. The partial objectives that arise are: 1) Development of a new methodology for selective exploitation according to demand, taking into account the quality requirements of the product on site. 2) Application of this methodology in the design and exploitation of new quarries, transforming the raw material and quality control by using non-destructive geophysical methods. 3) Definition of the methodology in order to reduce waste production and minimize sterilization of reserves. 4) Development of geostatistics methods for estimation of natural stone reserves.

The mine of the future will exploit mineral raw materials at greater depths than today, requiring completely different approaches compared to todays deep mines, in order to get mineral rights. Only these eco-efficient mines will contribute to improved access to domestic mineral resources, secure the supply of mineral raw materials for Europe and reduce the import dependency. IntelliMine will contribute to realise these concepts of invisible, zero-impact and safe mines. The mine of tomorrow will run an integrated concept. All operations necessary for the eco-efficient provision of the minerals including waste management will be carried out underground. This will drastically reduce the volumes being transported, minimising above ground installations and thus the environmental impact. IntelliMine will develop innovative methods, technologies, machines and equipment for the safe, eco-innovative, intelligent and economical exploitation of mineral raw materials in the EU, including maintenance issues, especially at greater depths. It will investigate autonomous, highly selective mineral extraction processes and machinery based on new sensor technologies as well as innovative concepts for mass flow management and transportation. Such investigations have to be accompanied by rock mechanics and ground control issues as well as health, safety and environmental issues. The concept of an invisible, zero-impact mine requires a refined process underground that selectively extracts the minerals and therefore reduces waste production closer to the mineralisation. Therefore improved near to face processing methods including backfill procedures need to be developed. The necessary level of automation in mining operations can only be achieved by reaching a higher level of integration in all parts of a mine. Fully integrated underground technologies and processes for diagnosis and extraction as well as communication, health and safety issues are the key for the success of the concept.

BioMOre describes a New Mining Concept for Extracting Metals from Deep Ore Deposits using Biotechnology. The concept is to use hydrofracturing for stimulation and bioleaching for winning of ores. The final process will consist of a so-called doublet, which is two deviated and parallel wells. In order to avoid high costs for drilling from the surface, the BioMOre approach is divided into two phases. Phase 1 will be research on the intended bioleaching process whereas phase 2 will aim at a pilot installation to demonstrate the applicability of the process in large scale including hydro-fracturing and access of the deposit from surface. The first phase should cover the intended work of the current BioMOre approach without drilling from surface. The BioMOre project aims at extracting metals from deep mineralized zones in Europe (Poland-Germany, Kupferschiefer deposit as a test case) by coupling solution mining and bioleaching. Selected sustainability indicators based on regulatory requirements of the European Commission will be applied for feasibility considerations. The main objective of the BioMOre first phase is to design and build an underground test facility for testing the concept of combined hydro-fracturing and bioleaching. The test facility will comprise a 100 m ore block, where boreholes will be drilled horizontally using standard equipment. All necessary equipment for testing different parameters of the intended bioleaching process will be established underground. The intention is to test the bioleaching process in high detail in an in-situ environment at the same time avoiding time consuming and risky permission procedures. On the other hand, the application for the permission of underground test operation must contain detailed information about monitoring of tests and all material controls. No harmful substances will remain in the mine after the tests are completed. Further to that, predictive numerical modelling of a pilot installation should be done.

European Commission Vice President Gnter Verheugen, responsible for enterprise and industry policy declared European industries need predictability in the flow of raw materials and stable prices to remain competitive. We are committed to improve the conditions of access to raw materials, be it within Europe or by creating a level playing field in accessing such materials from abroad. The global dimension of access to raw materials was on the agenda of the G8 Summit on June 2007. On that occasion a Declaration on Responsibility for raw materials: transparency and sustainable growth was adopted. Several national and international initiatives, both from the private or the institutional sectors, arised to address the sustainable development of the extractive industry and the reduction of its environmental footprint. Meanwhile, the extractive industry is facing increasing environmental and societal pressures, being regulatory or not, during all phases of a project, from exploration to exploitation and closure. The social acceptability of a project is among the major key issues to be dealt with. EO-MINERS scientific and technical objectives are to: - assess policy requirements at macro (public) and micro (mining companies) levels and define environmental, socio-economic, societal and sustainable development criteria and indicators to be possibly dealt using EO - use existing EO knowledge and carry out new developments on demonstration sites to further demonstrate the capabilities of integrated EO-based methods and tools in monitoring, managing and contributing reducing the environmental and societal footprints of the extractive industry during all phases of a mining project, from the exploration to the exploitation and closure stages - contribute making available reliable and objective information about affected ecosystems, populations and societies, to serve as a basis for a sound trialogue between industrialists, governmental organisations and stakeholder

In this work, the potential of CO mineral carbonation of brucite (Mg(OH)2) derived from the Mount Tawai peridotite (forsterite based (Mg)SiO4) to produce thermodynamically stable magnesium carbonate (MgCO3) was evaluated. The effect of three main factors (reaction temperature, particle size, and water vapor) were investigated in a sequence of experiments consisting of aqueous acid leaching, evaporation to dryness of the slurry mass, and then gas-solid carbonation under pressurized CO2. The maximum amount of Mg converted to MgCO is ~99%, which occurred at temperatures between 150 and 175 C. It was also found that the reduction of particle size range from >200 to <75 m enhanced the leaching rate significantly. In addition, the results showed the essential role of water vapor in promoting effective carbonation. By increasing water vapor concentration from 5 to 10 vol %, the mineral carbonation rate increased by 30%. This work has also numerically modeled the process by which CO gas may be sequestered, by reaction with forsterite in the presence of moisture. In both experimental analysis and geochemical modeling, the results showed that the reaction is favored and of high yield; going almost to completion (within about one year) with the bulk of the carbon partitioning into magnesite and that very little remains in solution.

Reduction of carbon dioxide (CO2) emissions into the atmosphere is a key challenge to mitigate the anthropogenic greenhouse effect. CO2 emissions cause lots of problems for the health of humans and increase global warming, in which CO2 uptake decreases these environmental issues. The mineral carbonation process is an alternative method during which industrial wastes rich in calcium (Ca) or magnesium (Mg) react with CO2 to form a stable carbonate mineral. In this research, the feasibility of CO2 mineral carbonation by the use of red gypsum, as a Ca-rich source, was evaluated using an autoclave mini reactor. Wide-range conditions of procedure variables, such as reaction temperature, reaction time, CO2 pressure, and liquid/solid ratio, on the rate of mineral carbonation were studied. The results showed that the maximum conversion of Ca (98.8%) is obtained at the condition that has an optimum amount of these variables. Moreover, the results confirmed that red gypsum has high potential to form calcium carbonate (CaCO3) during the process of CO2 mineral carbonation. It was concluded that the mineral carbonation process using red gypsum can be considered to be an interesting, applicable, and low-cost method in industry to mitigate a considerable amount of CO2 from the atmosphere, which is the main issue in the current and coming years. © 2014 American Chemical Society.

The novel low carbon scheme for manufacturing cement and concrete proposed in this paper combines three processes. First, a Portland-like cement is made at reduced temperature and cooled so that it self-pulverises to a powder of cement fineness without the need for grinding. Second, CO2 enriched gas is extracted from the cement kiln flue, and this may be used without further refinement in a third part of the process to activate this cement (which is only poorly hydraulic) in the production of precast concrete products. Considerable energy savings are anticipated, and additional sustainability gains arise from the closed loop manufacturing process. Proof of principle has been demonstrated and a preliminary estimate made of CO2 emission reduction: scale-up challenges are still to be addressed. The initial focus is on the production of precast concrete, where there is strong customer demand and regulatory pressure for low embodied carbon cements, together with a need for greater process efficiency. Other potential applications are foreseen in areas such as environmental engineering and non-structural concrete. © 2013 Institute of Materials, Minerals and Mining.

The objective of this work was to investigate the feasibility and effectiveness of silica fume on stabilizing heavy metals in municipal solid waste incineration (MSWI) fly ash. In addition to compressive strength measurements, hydrated pastes were characterized by X-ray diffraction (XRD), thermal-analyses (DTA/TG), and MAS NMR (27Al and 29Si) techniques. It was found that silica fume additions could effectively reduce the leaching of toxic heavy metals. At the addition of 20% silica fume, leaching concentrations for Cu, Pb and Zn of the hydrated paste cured for 7days decreased from 0.32mg/L to 0.05mg/L, 40.99mg/L to 4.40mg/L, and 6.96mg/L to 0.21mg/L compared with the MSWI fly ash. After curing for 135days, Cd and Pb in the leachates were not detected, while Cu and Zn concentrations decreased to 0.02mg/L and 0.03mg/L. The speciation of Pb and Cd by the modified version of the European Community Bureau of Reference (BCR) extractions showed that these metals converted into more stable state in hydrated pastes of MSWI fly ash in the presence of silica fume. Although exchangeable and weak-acid soluble fractions of Cu and Zn increased with hydration time, silica fume addition of 10% can satisfy the requirement of detoxification for heavy metals investigated in terms of the identification standard of hazardous waste of China. © 2014 Elsevier Ltd.
