Recovery Of Oxidized Copper Ore

Heap Leaching Oxide and Sulfide Copper Ores

The recoveries of copper from ores 1 and 2 (tables 3 and 4) were 55 percent in 50 days of leaching and 45 percent in 45 days of leaching, respectively. The initial leaching rates (figure 5) amounted to approximately 2 percent recovery per day for 14 or 15 days and then gradually dropped off to less than 0.5 percent per day.

Copper extraction - Wikipedia

When rich enough, native copper ore bodies may be treated to recover the contained copper via a gravity separation circuit where the density of the metal is used to liberate it from the lighter silicate minerals. Often, the nature of the gangue is important, as clay-rich native copper ores prove difficult to liberate.
