The electrowinning of copper ions derived from leaching, or solvent extraction is a significant contributor to the global copper commodity supply. The process of electrolysis for copper was first developed in the late 19th century and despite numerous advancements in technology the principles and basic equipment remain the same.

Other Complete Plants. Complete mining mill and crushing plants for recovery of copper, zinc, gold, gravel, coal and other ore types. Stage one would be where a crushing plant would be used and the process plant is the second stage of the recovery which is designed to extract the mineral or metal embedded in the ore or rock.
Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with appliions growing all the time.. While this process has proven to be efficient, often chosen for its costeffectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.

Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

Prospecting from Orbit. Mining for ore isn't what it used to be. A hundred years ago when a mining operation happened upon a copper vein or a gold deposit, the outfit would often just rip out the local flora, excavate the land, and dump the resulting waste and rubble in the nearest pristine stream or flowering meadow.
