Along with the copper extraction, iron (29.6 wt%), aluminum (70.2 wt%), magnesium (85.4 wt%), and calcium (44.4 wt%) were also leached out considerably through the dissolution of silicate and carbonate gangue minerals. In this study, an 80.0–94.26% copper extraction rate with reduced acid consumption (20%) proved to be a cost …
The Ore Grade and Depth Influence on Copper Energy Inputs
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 …
Copper Metallurgy | SpringerLink
In copper extraction, usually aldoxime or ketoxime extractant is used for chelating extraction (Fig. 4). In extraction, copper is enriched in the organic phase. The lean copper raffinate is returned to leaching process. The organic phase experiences reverse extraction in spent electrolyte (copper ion concentration 35 g/L, sulfuric acid ...
Extractive Metallurgy of Copper | ScienceDirect
Copper extraction is distinctly profitable when the selling price of copper is above $6/kg. It is unprofitable for some operations when the selling price falls below $3/kg. At the former price, the industry tends to expand. At the latter, it begins to contract. The selling price of copper in mid-2011 was ∼$9/kg.
From Ore to Finished Product
4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6.
SX Solvent Extraction Process Principles Theory
F. Capital Costs for Copper SX-EW. It is difficult to set out a formula by which to predict capital costs for solvent extraction-electrowinning plants. Raw material costs, local labor markets, the type of construction, the nature of the feed and the final plant design are variables important in predicting capital costs.
