leaching solvent extraction electrowinning process
DEVELOPMENT AND IMPLEMENTATION OF SOLVENT .
Leaching process for copper is accomplished with ammonia solution that metal such as copper is selectively extracted restricting the dissolution of iron or manganese. Both metals can pose a real problem in further stages of hydrometallurgical processing solvent extraction and electrowinning.
solvent extraction and electrowinning plant manufacturers
Solvent extraction and electrowinning (SX/EW) is a twostage hydrometallurgical process that first extracts and upgrades copper ions from lowgrade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent.

Next, mill operators thicken the slurry with water to form pulp and run the pulp through a series of leaching tanks. Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carboninpulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves.
