In this work, the feasibility of using alkaline cyanide solutions for leaching copper, gold, and silver from Cu/Au/Ag ores is analysed and compared with acid leaching.
We then calculate the sum of copper digested during these three digestions and compare the calculated copper to a total copper assay. The data gathered during this testing is important for flowsheet development and pilot plant design. SGS sequential leaching is a reliable solution to complex copper mineralogy in gold orebodies.
Copper Agitated Leaching and cementation process of copper problem: The treatment of copper ores, both oxides and sulfides by means of flotation, hydrometallurgy or other processes has been well established for many years. Flotation has been applied generally to the treatment of sulfide ores, both in small and large scale operations.

Copper Leaching Practices. For centuries small amounts of copper have been recovered from acid mine-drainage waters. In recent years, the expansion of copper-bearing waste dump leaching for copper recovery has established a technological basis that is rapidly converting the art of copper leaching into a science.
Vat Leaching Copper Ore. Vat leaching is a simple and efficient mode of effecting adequate contact between the solute and aqueous solvent. It utilizes the countercurrent principle, with the ore to be leached remaining stationary, as differentiated from most counter-current methods, where all materials are moving.
Copper has been the most common base metal extracted with bioleaching and according to some estimates, bioleached copper represents up to 15% of the world's copper production. Bio-oxidation has also been used to treat sulphide containing gold ores before leaching of the gold using chemical reagents.

In situ leaching (ISL), also known as in situ recovery, is a low capital-cost method of extracting uranium, copper or potash from suitable deposits. A suitable deposit is one where the commodity is located in saturated permeable horizons or distinctive geological areas that are bounded above and below by impermeable strata.
