Why Copper Leaching Is the Future of Copper Mining
March 17, 2023 No longer a "Stranded Resource" — New copper leaching technology is unlocking vast reserves of copper. For 10,000 years, copper has been mined the same way: by digging a hole in the ground, chipping out the copper, and then melting it down to refine it.

Innovations: How Hydrometallurgy and the SX/EW Process Made
Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by …

Acid Leaching
The method for recovery of copper from leach solutions by precipitation with iron has been known for many years, being reported in use by Rio Tinto Mines in Spain as early as 1752. Scrap iron, detinned cans and sponge iron have been used depending on cost and availability. Labor costs involved in the use of scrap iron and cans are usually ...

How copper dump leaching works
Abstract. In copper dump leaching, run-of-mine ore is irrigated with acidic leaching solution to generate aqueous cupric ions for further processing. The very large size of the ore particles being leached, as much as two meters in diameter, should preclude any significant metal recovery. Dump leaching should not work; and yet it does.
