Copper Ore - an overview | ScienceDirect Topics
Copper complexes that can be present in cyanide liquors include Cu (CN) 2 −, Cu (CN) 3 2 −, and Cu (CN) 4 3 − with the proportions dependent on the pH, copper concentration, and free cyanide concentration. The main issue facing the process engineer is the fact that minimization of cyanide consumption is favored by the formation of species with a low copper:cyanide mole ratio, e.g., Cu ...

NICKEL PLATING HANDBOOK
ELECTROPLATING PROCESS Electroplating is an electrolytic process for depositing a layer of metal upon a substrate to enhance the appearance or properties of the component. Electroplating is a form of electrodeposition. Although a wide range of metals can be electrodeposited, we will restrict our discussion to nickel plating.

Sulfur Mining | Processing Equipment | Flow Chart | Cases ...
Sulfur attaches to metal ions, creating a number of significant sulfide ore minerals such as galena (lead sulfide), pyrite (iron sulfide), chalcocite (copper sulfide), and sphalerite (zinc sulfide). Mined sulfur is mostly from salt domes or bedded deposits. The vast majority is produced as a by-product of oil refining and natural gas processing.

Copper Sulfide - an overview | ScienceDirect Topics
All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur. The copper sulfide is oxidized by Fe 3+.The resulting Fe 2+ is reoxidized to Fe 3+ by O 2.The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevated-temperature reaction conditions where the sulfur-containing product is sulfate, rather than the elemental ...
