All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.. Carbonate concentrates are a relatively minor product ...
This thesis presents the work done in a collaborative research project between the University of British Columbia and Highland Valley Copper. The research was aimed at understanding gyratory crusher liner wear in the overall context of the crushing process. Wear measurements were taken for in-service crushers during the research period using a novel laser profile measurement device. Data from ...
crushing is hauled to the primary crusher hopper. Ore suitable for immediate heap leaching is delivered directly to the leach pad. Development rock (waste rock with low-grade copper) from San Juan Mine is transported to Development Rock Stockpiles for future use.
The primary reason for the selection of heap leaching is the low grade nature of the deposit and the vast scale of the ore body. The flowsheet development was based on the measured and indicated resource of 456.9 Mt at 0.31% copper.
A number of mine plans based on different metal prices can be developed to help the mine better respond to changing market conditions. When the price of copper is high, lower-grade ore can be cost-effectively mined along with the better grade ore. When the price is low, the mining operations can focus on the higher grade ores.

Sep 23, 2020· 2.4 Iron oxide copper gold mineral system Geoscience. Iron oxide copper-gold (IOCG) deposits (Hitzman et al., 1992) are a diverse family of mineral deposits characterised by the following features: (1) Cu with or without Au, as economic metals, (2) hydrothermal ore styles and strong structural controls, (3) abundant magnetite and/or hematite, (4) Fe oxides with Fe/Ti greater than those in most ...
The primary reasons for the selection of heap leaching are the low-grade nature of the deposit and the vast scale of the mineral body. Previous work conducted on the Haib Project suggested that a conventional crush-grind-float and sale of copper concentrate is not economically feasible under the current copper market conditions.
