The copper concentrate has the following phase composition, % (relative): 1.48 oxi dized; 25.35 secondary; 70.28 primary; 2.89 gray copper ore; 100 total. The comparison of data from Tables 2 and 3 yields that the incremental content of copper in the copper concentrate is achieved owing to primary copper minerals. Molybdenum concentrate.
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Zhang et al. [23] studied the process mineralogy of copper ores and found that copper minerals are mainly sulfide minerals that are easily floated, but most of them are embedded at around 0.3 mm, requiring a grinding fineness of 85–90 % −300 mesh to make the copper ore fully dissociated. The study of process mineralogy holds a significant ...
Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by

How much ore is required to obtain 400 g of copper? (a) 2 kg (b) 4 kg (c) 6 kg (d) 8 kg. View Solution. Q4. An ore contains 20 % zinc. How many k g of ore will be required to get 45 k g of zinc? View Solution. Q5. An arc contains 23 % copper. To get 69 % of copper the quantity of the arc required is:
8 kg ore Explanation - Given that an ore contains 5% copper. Let x be amount of ore required to obtain 400 g copper. 5% of x = 400 g. 5/100 × x = 400. x = 400 × 100 / 5. x = 400 × 20. x = 8000 g. x = 8 kg. Hence, 8 kg ore is required to obtain 400 g of copper. Thanks dear. Hope that helps you...
The study evaluated implications of different ore grades and mine-depth on the energy inputs to extract and process copper. Based on a 191 value dataset from 28 copper mining operations, seven model equations explaining operational energy costs were statistically evaluated. Energy costs for copper mines with leaching operations …
