Processing of copper electrorefining anode slime: a

2013718&ensp·&enspAbstract. Anode slime is the insoluble product deposited at the bottom of the electrorefining tank during electrorefining of copper. It generally contains Cu, Ni, Se, Te, Ag, Au, platinum group metals (PGM), Pb, Ba, Fe, etc. Owing to the presence of valuable metals and metalloids in the anode slime, numerous approaches have been made by the researchers to extract them following pyro

Lime use and functionality in sulphide mineral

2019111&ensp·&enspGibson and Kelebek (2014) conducted a study on two types of complex NiCu sulphide ores and found that when lime was replaced by soda ash (Na 2 CO 3) as pH modifier, the adverse effect of hydrophilic calcium species on pentlandite was largely eliminated and the minerals flotability restored. Chalcopyrite flotation recovery was less affected

2020518&ensp·&enspWhile there are over 45 different nickel minerals, only a few of them are of economic importance to the minerals industry. The principal nickel mineral in nickel sulphide ores is pentlandite ((Ni,Fe)8S9) while the less common nickel sulphides include millerite (NiS). violarite (Ni2FeS4), polydymite (Ni3S4), siegenitc {(Co,Ni)3S4), and heazlewoodite (Ni3S2).

Combustion synthesis of nanocrystalline silicon from

, , with no processing costs. Table 1 shows that the silicon obtained using Mg 2 Si is 2.2 times more expensive than that obtained using Mg. A second estimate was made based on the costs of mineral commodities. Note that this approach has been used for estimating costs of compounds and alloys [7,27].
