A simplified schematic drawing of copper flotation flowsheet. Run-of-mine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semi-autogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate. The concentrate will be trucked via the existing road network in the area to a

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

The lead-copper-silver concentrate is conditioned in a 4′ x 4′ Super-Conditioner with cyanide for depression of copper. The flotation of the lead from the copper is conducted in a 6-cell No. 15 “Sub-A” Flotation Machine, having 3 stages of separation. The silver is equally distributed with the lead and the copper concentrate.
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. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of large-scale mining projects involving these metal ores are the subject of this Guidebook. The Guidebook does not discuss the mining of ores that are extracted using strip mining methods
Modern hydrometallurgical flowsheets all comprise three essential steps for the recovery of copper: leaching, followed by solvent extraction and electrowinning. Leaching involves dissolving Cu 2+ (or Cu + ) from copper-containing minerals into an aqueous H 2 SO 4 solution, known as the lixiviant,to produce a pregnant leach solution (PLS).
