Morenci Copper Mine, Arizona Mining Technology

Low-grade ore is ball-milled before being agglomerated and dump-leached to recover its copper content. The Detroit Copper Company started mining at Morenci, 16km south of Silver City, Arizona, in 1872. Copper Queen Consolidated Mining bought the property in 1885, with the company name changed to Phelps Dodge in 1917.

Solution Collection System For a ROM Leach Dump: Design

In the mining industry, leaching is a hydro-metallurgical process that separates valuable minerals from ore by dissolving the mineral with a dilute cyanide solution in the case of gold, or a sulfuric acid to dissolve copper (Hearn RL & Hoye R 1998). Dump leaching is a technique where run-of-mine low grade

Heap leaching Wikipedia

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 the ore, whereas in

HEAP LEACHING TECHNIQUE in MINING

Leaching is a physico-chemical process where minerals in rock masses go through dissolution under percolating water and anion/cation exchange reactions to generate metal salts in solute/colloid phase that migrate and accumulate under hydrological forces. Depending on the presence of pyrite (FeS) or pyrrhotite (Fe 1-x S) and
