This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores …
Furthermore, a large portion of the copper in the concentrate material is suspected to be in the form of chalcopyrite, whereas the nickel is largely in the form of pentlandite (Evans, 2007, Schouwstra and Kinloch, 2000). Chalcopyrite and pentlandite are leached according to Eq. ... Download : Download full-size image; Fig. 5. Flowsheet.
Cu, Ni and Co leach extraction from the concentrate was 95%, 95%, and 97%, respectfully. Based on pilot plant metallurgical results, overall metal recoveries are presented in Table 15. Metal recovery from the leach liquor was excellent due to low Ni/Co losses in residue and byproducts, and complete recycle of all solutions.
The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3% cobalt and 1.3% copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11. The concentrate typically contains about 16% copper and 4% cobalt.
