Copper Leach Plant for Sale
The use of continuous vat leaching is a preferred method of leaching copper ore over both agitated tank leaching and heap leaching. Due to the high capital and operating costs, agitated tank leaching is limited to high-grade, finely ground ores or concentrates. Current practice is to heap leach crushed ore for production of cathode copper.The actual leaching of the copper in Chalcopyrite takes place as a result of the reaction with ferric sulfate. Bacteria, which requires oxygen to survive, produces ferrous sulfate from the sulfides and breaks down the matrices for access to the metal. Conversion from ferrous sulfate to ferric sulfate can be accomplished by the addition of air.
Mobile Copper Leach Plant
A fundamental processing problem with heap leaching of copper ore is that control of what happens within the heap is very limited. Once the solution is applied, the time lag required in detecting difficulties and taking corrective action is long, indeed—often years. One can only hope that there is enough basic product being harvested to make up for deficiencies encountered in the learning process.
