    Thiocyanate leaching of gold UBC Library Open Collections

    The tests ended with gold adsorption from thiocyanate solution onto carbon. The average gold loading onto carbon was 2100 g/t and 48 g/t for carbon concentrations of 0.25 g/L and 20 g/L, respectively. Results obtained were excellent with greater than 98 % gold adsorbed in less than 0.5 hr when carbon concentration was above 5 g/L.

    Feb 15, 2008 In low ionic strength artificial fresh water, a short-term (30 min) exposure to 20 g/L dissolved copper reduced the olfactory response to a natural odorant (10−5 M L-serine) by 82%. Increasing water hardness (0.2–1.6 mM Ca) or alkalinity (0.2–3.2 mM HCO3−) only slightly diminished the inhibitory effects of copper.

    Fundamental study on tin recovery in acidic aqueous

    Tin is widely used in solder, tin plating and tin alloys. The current recovery rate of tin metal is low and insufficient with just over 300,000 tonnes annually. The grade of tin concentrates in traditional smelting methods needs to be at least 60%. Otherwise, iron, the chief impurity in tin concentrates can form tin-iron alloys and result in inefficient recovery of tin. Therefore, a ...

    The modes of gold loss in the calcium thiosulfate leaching

    The processing of gold is becoming more complicated due to the increasingly complex nature of the remaining gold-bearing ore bodies. This worldwide phenomenon is the driving force for the development of alternative technologies for the leaching and recovery of gold from so-called double refractory ores. Barrick Gold recently commercialized a unique calcium thiosulfate leaching plant to treat ...

    ZnO + H 2 S → ZnS + H 2 O Laboratory preparation. It is easily produced by igniting a mixture of zinc and sulfur. Since zinc sulfide is insoluble in water, it can also be produced in a precipitation reaction. Solutions containing Zn 2+ salts readily form a precipitate ZnS in the presence of sulfide ions (e.g., from H 2 S). Zn 2+ + S 2− → ZnS
