Kaolin is used in many consumer products and as a functional additive and process enabler in manufacturing. It is typically extracted from open-pit mines that range from small to very large scale (tens to hundreds of thousands of dry metric tons produced per year). Ore processing consists of removing impurities, engineering particle size and shape, and enhancing certain properties through thermal and chemical treatment. In addition to the technical aspects of mining and processing, the social, environmental, and economic impacts of kaolin production are managed at each stage of the mining life cycle. Discussed herein are aspects of the history of kaolin mining, the classifi cation of kaolin mines, the processing of kaolin, and the life cycle of mining.

A process for making microcapsules may include i) forming a solution of a cross-linker in a liquid; ii) forming a slurry of a surface-modified particulate inorganic material in an aqueous medium; and iii) dispersing the solution of step i) in the slurry of step ii) and causing or allowing the cross-linker to react with the surface-modified particulate inorganic material so as to form a cross-linked microcapsule wall.


A mineral composition and related methods may include a mineral treated with a styrene-based polymer. The mineral treated with a styrene-based polymer may be used for a coating on a paper product having a first Cobb value that is less than a second Cobb value of the paper product with the coating devoid of the mineral composition.

Li-ion technologies initiated in the 90 at a fast development pace thanks mainly to emerging ICTs with more than 20 GWh sold in 2010. Soon, it appeared as a credible technology for electrical vehicles as it could provide average energy densities of about 140 Wh/kg. However and since then,major breakthroughs have been expected to reach higher storage levels of 250 Wh/kg on battery system level with an acceptable lifetime of 3000 cycles in order to develop an affordable economical business plan for car batteries. MAT4BAT builds-up its EVs battery strategy on advanced materials and pilot line processes, proposing three novel concepts of cells initiating from a state-of-the art combination of cell materials (NMC/Carbonate liquid electrolyte/Graphite). MAT4BAT will address all critical ageing mechanisms associated to this technology and having direct impacts on product lifetime & safety by implementing two work programs for Battery Assessment (#1) and Battery Technologies (#2). Program #1 will set a framework to define critical charging modalities for a battery system during practical use and associated testing tools & methods for relevant functional performance & lifetime assessment. Within this framework, the program #2 will implement three generations of cells with a focus on electrolytes which will be steadily transformed from Liquid to Gel to All-Solid state electrolytes in order to promote substantial gain in cell lifetime and safety by preventing degradations and hazards and improving energy density with a separator-free cell (all-solid state electrolyte). 100 state-of-the-art commercial cells will be assessed to define normal and critical charge/discharge conditions of testing with appropriate testing protocols. Besides,materials increments will be screened out on coin-cells prior a benchmarking of most promising materials at full cells level. Eventually,(10-40 A.h) prototypes will be produced to validate MAT4BAT best technologies against quantified objectives.
