Influence of Ferric and Ferrous Iron on Chemical and

The effects of ferrous and ferric iron as well as redox potential on copper and iron extraction from the copper flotation concentrate of Sarcheshmeh, Kerman, Iran, were evaluated using shake flask leaching examinations. Experiments were carried out in the presence and absence of a mixed culture of moderately thermophile microorganisms at 50C. Chemi-˚ cal leaching experiments were performed in

Cobaltite - Wikipedia

Cobaltite is a sulfide mineral composed of cobalt, arsenic, and sulfur, Co As S.Its impurities may contains up to 10% iron and variable amounts of nickel. Structurally, it resembles pyrite (FeS 2) with one of the sulfur atoms replaced by an arsenic atom.. Although rare, it is mined as a significant source of the strategically important metal cobalt.Secondary weathering incrustations of

Chalcocite and Pyrite, 200x . Dark veinlets of chalcocite (Cu 2 S) transecting a pyrite particle. Froth flotation of this ore yielded unacceptably low copper concentrate grades due to insufficient pyrite-chalcocite liberation and attendant pyrite carryover into the concentrate. Based on the results of microscopic studies of this ore, the mill operators learned to properly blend ore types and

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing

Copper Mining and Extraction Sulfide Ores

Stage 2: Froth flotation The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a foaming agent which produces a kind of bubble bath. This is a rare chance to see a mill and flotation building before the roof is built.

Cyanide chemistry and its effect on mineral

Flotation recovery as a function of potential for chalcocite, chalcopyrite, and pyrite at pH = 9.2; [EX] = 1.44 × 10 −5 M for chalcocite and 2 × 10 −5 M for other sulphides (Ralston, 1991). In the presence of free cyanide, the surface potential of pyrite may be lower than the xanthate/dixanthogen equilibrium potential, thus inhibiting the electrochemical oxidation of xanthate according
