Ruby explorer Mustang Resources (AU:MUS) has appointed former Orbis Gold managing director Peter Spiers to the board as a non-executive director. Spiers, who will start the job immediately, worked for the Western Mining Corporation for 20 years as a geologist and then group manager before it was taken over by BHP-Billiton (AU:BHP) in 2005. He ran Orbis until it was bought out in 2015. Mustang chairman Ian Draymond said Spiers had useful experience on both the operations and sales side of mining. “Peter’s experience in a wide range of technical and commercial roles within the resources industry means he is perfectly placed to assist Mustang as we ramp up ruby production ahead of our first auction in October,” he said. “Peter will be able to provide valuable advice, ranging from exploration and project development through to marketing and commercial issues as we continue work to unlock the value of our outstanding assets.” Spiers joins Draymond, managing director Christiaan Jordaan and Cobus Van Wyk on the Mustang board.

An experimental technique for determining the spalling strength of rock-like materials under a high strain rate is developed. It is observed that the spalling strength of a specimen can be determined by only knowing the wavelength, loading peak value and length of the first spallation of an incident wave under a specific loading waveform. Using this method in combination with a split-Hopkinson pressure bar (SHPB) and other experimental devices, the spalling strength of granite specimens under a high strain rate is tested. Comparisons with other experimental results show that the new measuring method can accurately calculate the dynamic tensile strength of rock materials under a high strain rate. © 2017 Techno-Press, Ltd.

The adsorption behaviour of methylcellulose on talc surface and the stimulus response of methylcellulose on talc flotation were studied through flotation tests,adsorption experiments and zeta potential measurements.. The results show that methylcellulose dissolved in water and hydrophobic interaction is the main driving force for adsorption at the low temperature. When the temperature increases, methylcellulose precipitation from solution and deposited on talc surface, the adsorption amount is large and the depression effect is strong. The depression effect of adsorbed methylcellulose layer on talc flotation is also affected by temperature. The switch of temperature from low to high results in decreased depression effect of methylcellulose and the change is reversible. The reason is that the hydroxyl of methylcellulose form hydrogen bonds with water molecules at low temperature, leading to a hydrophilic mineral surface and strong depression effect on talc. When the temperature rises, methylcellulose molecules lose water and the water content decreases, the depression effect to talc also decreases. © 2017, Science Press. All right reserved.

The oxidation behavior of artificial magnetite pellets was investigated through measurements of the oxidation degree and mineralogical analysis. The results show that artificial magnetite pellets are much easier to oxidize than natural magnetite. The oxidation is controlled through two different reaction mechanisms. The oxidation of artificial magnetite is dominated by internal diffusion, with an activation energy of 8.40 kJ/mol, at temperatures less than 800°C, whereas it is controlled by chemical reaction, with a reaction activation energy of 67.79 kJ/mol, at temperatures greater than 800°C. In addition, factors such as the oxygen volume fraction and the pellet diameter strongly influence the oxidation of artificial magnetite: a larger oxygen volume fraction and a smaller pellet diameter result in a much faster oxidation process. © 2017, University of Science and Technology Beijing and Springer-Verlag Berlin Heidelberg.

Abstract The flotation separation of scheelite from calcite using sodium oleate as collector and acidified sodium silicate as depressant has been studied. The results show that sodium oleate has collecting ability to both scheelite and calcite and the flotation separation of scheelite from calcite cannot be realized if collector is used only. The depressant acidified sodium silicate has selective depression effect on calcite and the optimum ratio of sodium silicate to oxalic is 3:1. The use of acidified sodium silicate as depressant can achieve the flotation separation of scheelite from calcite. Infrared studies and zeta potential measurements showed that the pre-adsorption of acidified sodium silicate interferes with the adsorption of sodium oleate on calcite surface while does not interfere with its adsorption on scheelite surface. © 2015 Elsevier Ltd.

A novel material, the biochar of a konjac-based material (KGMB), was prepared conveniently and economically with chemical activation of hydrothermally synthesized carbon nanospheres. Those carbon nanospheres have small sizes and high surface areas due to the high temperature sintering, which could be used for efficient adsorption of heavy metal ions such as Pb2+ and Cd2+. Detailed adsorption behaviors of the optimized biochar including adsorption isotherms and adsorption kinetics were investigated. The results indicated that the adsorption process is spontaneous, exothermic and pseudo-second-order chemisorption. When the temperature was 298 K, the KGMB dose was 5 mg, the initial concentration of Pb2+ and Cd2+ was both 50 mg L-1, the contact time was 24 h and pH of the ion solution was 5.5, the adsorption capacity reached up to 186.56 mg g-1 for Pb2+ and 129.67 mg g-1 for Cd2+, respectively. What's more, the adsorption capacities of Pb2+ and Cd2+ were 69.34 and 71.06 mg g-1, respectively, after adsorption-desorption process happened three times. Comparisons of the adsorption capacity of various adsorbents for Pb2+ and Cd2+, showed that this biochar is superior to many other adsorbents in terms of adsorption capacity and it is a cheap, efficient and accessible biochar. Thus, KGMB is a promising candidate for wastewater treatment. © 2016 The Royal Society of Chemistry.

Carboxymethyl inulin (CMI) is one of the most promising biomass materials for scale inhibition. Its potential applications as a scale inhibitor have attracted much research attention. Understanding the interactions between CMI and calcite surfaces is very important for the design of scale inhibitors. In this study, molecular dynamics simulations were carried out to investigate effects of temperature, CMI chain length, and calcite cleavage on the interactions between CMI and calcite. The results indicate that for the same mass of CMI (with different degrees of polymerization, n = 1, 3, 5), CMI exhibits different abilities in inhibiting the growth of calcite crystal in the order of CMI (n = 5) > CMI (n = 3) >. CMI (n = 1) for calcite (012), (104), 11{combining overline}0, and (110) surfaces. For the calcite (012) surface, the inhibition ability is similar for CMI (n = 3) and CMI (n = 5). For the aqueous environment, comparison of the results of water effects with the results for the CMI-calcite surfaces without water showed a similar trend: the interaction between the CMI and the calcite (012) surface was greater than that of the CMI with the other calcite surfaces (104), (110), and 11{combining overline}0. However, the interactions between the CMI and the other calcite surfaces (104), (110), and 11{combining overline}0 were apparently weakened by the water environment. The results also show that temperature influences the interactions between CMI and calcite surfaces. This study provides important information for CMI potential applications as calcite inhibitor. © 2015 Elsevier B.V.

In this paper, based on the experiment on pure minerals, namely, galena, sphalerite and pyrite, it is concluded that the appropriate pH range for galena flotation is 8.5-10.5, that for sphalerite flotation is 7-10.5 and for pyrite is 2.5-6.5. For galena, sphalerite and pyrite, butyl xanthate has a better collecting performance than ammonium dibutyl dithiophosphate. Both Na 2SO3 and ZnSO4 have a relatively weak inhibitory effect on galena. As for sphalerite, the mixing of Na 2SO3 and ZnSO4 has a better inhibitory effect than when they are used alone, with the best inhibitory effect obtained when the proportion of Na2SO3 and ZnSO4 is 1:2 and their dosages are respectively 100mg/L and 200mg/L. In zinc flotation, CuSO 4 demonstrates an apparent activating effect on the inhibited sphalerite with its appropriate dosage at 2*10 -4 mol/L. In actual separation and selection of ore, when the grades of lead, zinc and silver in cyanide tailings are respectively 2.41%, 3.77% and 272g/t, a fairly good index is obtained where the Pb concentrate is of a grade of 33.41% with its silver grade of 4051.57g/t and the grade of Zn concentrate is 59.67% with its silver grade of 798.08g/t. © (2012) Trans Tech Publications, Switzerland.

Two-stage countercurrent oxygen pressure acid leaching process was developed to recover valuable metals from Gacun complex copper concentrate. It is unusual that tetrahedrite, whose treatment has been rarely studied, is the primary copper mineral of a concentrate. Most of silver also occurs in the mineral. The optimum operating parameters of the first stage and the second stage were established by conditional tests. Pilot scale tests ran smoothly, and the average overall leaching percentages of copper and zinc were as high as 96.2% and 97.5% respectively while the average overall leaching percentages of Fe, As and Sb as impurities were only 8.5%, 6.5% and 0.8%. Pb and Ag were not dissolved and stayed in the second stage leaching residue. © 2011 Elsevier Ltd. All rights reserved.
