Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines. The crushed mine ore is ground in rod and ball mills and then sent to flotation machines where the copper mineral rises to the top in a froth, making a copper concentrate of approximately 30 percent, 27 percent iron and 33 percent sulfur.

leach liquor were collected at intervals of 10, 30, 60, and 120 minutes during the experiment. Leach liquor samples were collected, filtered and sent for chemical analysis to determine copper concentration in aqueous solution. Results and Discussion Table 2 shows the percentage of copper extracted from different leaching agents.

4 Additives – Mostly Proprietary Brighteners – are plating accelerators, which act as a micro-leveler and impact grain refinement. They tend to be attracted to cathode induction zone points of higher electro-potential, temporarily packing the area and forcing copper to deposit elsewhere.

In 2011 leaching, both heap leaching and in-situ leaching, produced 3.4 million metric tons of copper, 22 percent of world production. The largest copper heap leach operations are in Chile, Peru, and the southwestern United States. Although heap leaching is a low cost-process, it .

is replenished and returned to the leach pad for reuse. After the extraction stage, the copper-loaded extractant is fed to the stripping unit, where the copper is transferred from the organic solution to a Figure 1. Simplified flow diagram of copper leaching, solvent extraction and electrowinning process.

Ball milling of the concentrate from 0 to 180 minutes led to an increase in the efficiency of copper leaching in a acidic ferric chloride solution from 43 to 86%. Copper recovery was completed after 360, 540, 960, and 1440 minutes of leaching for the samples subjected to ball milling for 300, 240, 120, and 60 minutes, respectively.

Copper-containing minerals are problematic, because it forms stable copper-cyanide complexes upon leaching with cyanide. The dissolution of copper consumes a substantial quantity of cyanide, thereby increasing reagent costs. ... sample of the resin and steel balls are placed in a cylinder filled with water, and milled for a period ...

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. Ninety years later in March 2007, Phelps Dodge merged with Freeport McMoRan Copper ...

The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing it to walnut-sized pieces. Crushed ore is ball or rod-milled in large, rotating, cylindrical machines until it becomes a powder usually containing less than 1 percent copper.

Copper Leaching Practices. For centuries small amounts of copper have been recovered from acid mine-drainage waters. In recent years, the expansion of copper-bearing waste dump leaching for copper recovery has established a technological basis that is rapidly converting the art of copper leaching into a science.
