Innovations in Copper: Mining Extraction: Producing copper nature's way: Bioleaching

Quoted operating costs (2002), based on current technology for leaching dumps and in-place ore, are between US$0.18 and US$0.22 per pound of cathode copper, which are competitive with the unit costs of smelting/refining. Heap leaching has the additional cost of mining and transporting to the leach pad. In some operations additional costs are incurred wherein the ROM is crushed and mixed with ...

Agglomeration Drums in the Heap Leaching Process

Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time. While this process has proven to be efficient, often chosen for its cost-effectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum .

Leaching of high grade copper oxide ore is a first order lixivant controlled in so much as the lixivant supply to the mineral surface is constrained by lixivant concentration and percolation rate. However in low grade copper and oxide gold heap leaching the reaction is more diffusion controlled as the lixivant is mostly present in excess. Figure 5 shows a simplified shrinking core. Unleached ...

Mining and Extraction: Oxide Ores - processes for extracting copper

This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. A by-product of the smelting and converting furnaces is sulfuric acid. In what looks like a lucky coincidence, sulfuric acid is needed to treat oxide ores in processes called leaching and SX-EW (Solvent Extraction – Electrowinning). The acid ...

Heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components: Crushed ore is stacked on a leaching pad and irrigated with the leaching agent. The leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it percolates through the heap. The impregnated solution can then be collected
