2015-9-18  Jan 11, 2018 Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable.get price

Copper(II) complexation and extraction with 2

The existence regions of copper (II), zinc(II), nickel(II), and cobalt(II) complexes formed upon extraction with DBH in kerosene were studied. The neutral complex ML 2 extracted over a wide pH range (from pH ∼ 6 to \(c_{NH_3 } \) ∼ 4 mol/L) is formed only by copper(II), while zinc(II), nickel(II), and cobalt(II) react with DBH to yield precipitates that float at pH 7–9, 9–10.5, and 9.5–11, respectively.get price
