Benefits of Agglomeration in an SX

Heap Leaching Copper Ore with Agglomeration Crushed copper ore is first typically processed via heap leaching An effective leaching step is critical to SX-EW, as it sets the stage for how much copper can be recovered For this reason, the heap leaching step is commonly preceded by agglomeration of the ore in a rotary drum agglomerator...

Gold ore with 152% copper

At that copper grade it is a copper ore and you could make a copper flotation concentrate to capture the majority of the copper and gold The copper concentrate can be sold directly to a smelter who will pay you for teh copper and gold with some deduction If there is remaining gold in the tails you could leach it with cyanide...

Morenci Copper Mine, Arizona

For many years as an integrated mine-concentrator-smelter operation, Morenci pioneered the large-scale hydrometallurgical treatment of mined copper ore by dump leaching, solvent extraction (SX) and electrowinning (EW) during 1985, in parallel with conventional treatment In 1999, Phelps Dodge started a $220m mine-for-leach (MFL) conversion ....

Copper Production: How Is Copper Made?

Sep 26, 2019· The development of SX-EW has allowed copper extraction in areas where sulfuric acid is not available or cannot be produced from sulfur within the copper ore body, as well as from old sulfide minerals that have been oxidized by exposure to air or bacterial leaching and other waste materials that would have previously been disposed of unprocessed...

Heap leaching

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to ,...
