:: Giant Leap in Copper Leaching Technology

A new leaching technology from FLSmidth can increase copper output by 3%. That would mean an extra USD 40 million per year for an average copper mine with primary sulfide ore. The top ore layer of an open pit copper mine is easily processed using heap leach in tandem with solvent extraction and electrowinning to produce copper cathodes. The copper mineral most predominate in mines is

Copper recovery using leach/solvent extraction ...

copper leach solutions which could be effectively treated by SX using LIX 64 to ≤3 g/l Cu at a pH ≥1.8. In 1968 the copper industry as a whole did not believe large quantities of high quality copper could be produced by hydrometallurgy and at the time the Ranchers plant came on line, expectations for the eventual success of copper L/SX/EW technology were rather modest. Ranchers’ Bluebird ...

Innovations in Copper: Mining Extraction: Producing ...

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 ...

FLSmidth claims copper-leaching technology leap -

For copper producers, the company said that the new technology could mean a renewed business case for remaining deposits: several existing mines have lost the ability to make copper concentrates suitable for smelting. The FLSmidth Rapid Oxidative Leach technology can make it possible to recover more copper from low grade concentrate.

GALVANOX™ – A NOVEL GALVANICALLY-ASSISTED

18/07/2013  A novel technology for leaching copper from primary copper concentrates has been developed at the University of British Columbia (UBC). This patented technology takes advantage of the galvanic couple between pyrite and chalcopyrite to ensure rapid and complete oxidation of chalcopyrite under mild conditions in acidic iron sulfate solution, without the need for microbes, ultrafine grinding or ...

How Hydrometallurgy and the SX/EW Process Made

A second technology that has aided in the production of environmentally clean copper is that of bacterial leaching or bioleaching. This is used as an adjunct to the SX/EW process in situations where sulfide copper minerals must be leached. Modern commercial application of bacterial leaching began in the 1950s at Kennecott's Bingham mine near Salt Lake City, Utah. It was noticed that blue ...

The technology selected is the dump leaching of copper and other metal values from low-grade copper ores. The portion of the presently used process to be placed in this case is the solvent extraction (SX) train in which the copper in solution is separated from the leach liquor from dump leaching. Instead of SX, we use the CAC for the separation and immediately obtain two advantages: (1) We can ...
