How to Process Copper Ore: Beneficiation Methods and

May 28, 2020· Chemical beneficiation of copper oxide ore Acid leaching—precipitation—flotation. Scope of application: malachite, cuprite, tenorite, copper mine tailings, etc., except copper ore containing calcium magnesium carbonate gangue. The ore is first leached with a 0.5% to 3% sulfuric acid dilute solution after being ground.

and beneficiation activities (including dust control), pumped to tailings impoundments, or discharged as a waste through an NPDES permit. Because mine water at copper mines is often rich in dissolved copper and other metal ions, some operations pump it to an SX/EW plant to recover the copper values (Cumming 1973).

CN103157558A Beneficiation method of recovering sulfur

The invention belongs to the field of mineral processing, relates to a beneficiation method, and particularly relates to a method of sorting copper sulfide ore flotation tailings. The method comprises the following steps: A, the tailings with copper and sulfur separated are dewatered through a thickener, wherein the content of the sulfur in the tailings is more than 20%, and the concentration

Geochemical and mineralogical characterization of tailings

The Dexing copper mine is the largest open pit copper mines in Asia, with mining and beneficiation history stretching back more than half a century; consequently it has large amounts of ore tailings. The mineralogy, chemical composition and distribution of elements in the impounded tailings are of great significance to the future utilization

Economic Potential for reprocessing Copper Mine Tailings

A total of 81 tailings samples were analyzed using XRF, during the survey sampling. The copper grade of the tailings varied between 0.1 % and 1.7 %. Further elements of interest were iron, gold, molybdenum and zinc. This data and the tonnage of the tailings ponds was the basis to select four sites for a more detailed
