A new method of extracting copper from mixed mineral (polysulfide oxidant) copper with or without hooked calcium copper and sulphuric acid leaching

摘要

Procedures for the extraction of copper from mixed copper ores with or without bagasse calcium and sulphuric acid include: (a) crushing and classifying the mixed copper ores; and (b) leaching the ores into the Exfiltration and agitation systems. (c) adding sulfamide dissolved in aqueous solution as leaching reagent of mixed copper minerals to produce a series of reactions related to calcium carbonate, copper oxidant, such as cuprita, tenorita, malaquita, etc., including copper sulfide and native copper, Copper sulfate II was obtained as the main product of pls,(d) clarification and filtration of PLS, (E) purification of PLS by solvent extraction process to obtain high purity cupric sulfate II rich electrolyte, (f) precipitation of calcium from rafinat (effluent from solvent extraction process) to rafinato Poza, (H) electroplating of copper, It is rich in the metal copper with 99 999% purity in the electrode cell.
