There are two big opportunities for DES in copper processing: first, the processing of copper deposits in jurisdictions with water usage sensitives and, second, the processing via leaching of transition ores and copper sulphides.
Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …
Copper is the most used industrial metal after iron and aluminium, with electrical applications accounting for approximately three quarters of total copper use. Mining Technology keeps track of the global copper market by observing copper price trends and analysing country-wise copper production, consumption and export and import data.
The ore is stockpiled before transferring into the grinding circuit. The grinding circuit includes a semi-autogenous ball milling-crushing circuit containing a SAG mill and two fixed speed ball mills. The processed ore is then sent to the 28Mt/y concentrator plant containing a copper and molybdenum flotation circuit. Ore processing

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.
Founded in 2021, Ceibo is one of several mining technology startups that's proposing a new, old approach to getting copper out of low-grade sulfide ores: a process known as heap leaching.

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.
We apply our catalysts to hundreds of millions of tons of ore and significantly increase copper yields in a cost effective and environmentally responsible manner. From laboratory to reality Jetti makes it possible to extract copper from low-grade primary sulfides, such as chalcopyrite, the world's most abundant copper mineral ore.
