The 300t of copper recovered is not from 100,000t of ore but rather 40,000t of ore that was actually available for leaching. The remainder of the ore is locked up in macro particles that will take years to leach. The ore did in fact leach well and there are not mineralogical or metallurgical problems.

LeachingMining Fundamentals

LeachingMining Fundamentals

The pre-processing of ore before leaching involves the grinding and roasting of the ore. Roasting is done to remove the carbonaceous elements trapped inside the ore. After pre-processing, the ore is leached with acid of alkali solutions to extract the metal. Heap leaching is carried out in the extraction of copper, nickel, uranium and precious .

From Ore to Finished ProductCopper

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Copper Mining and Extraction: Oxide Ores

Copper Mining and Extraction: Oxide Ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
