Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

The operating cost was shown to reduce to US$5.36/kg to US$3.66/kg, for a similar recovery range, if the current SX and EW facility can absorb the bio heap leaching solution (Scenario 2). Using the operating cost data and the current copper selling price, the ore cut-off grade as a function of copper extraction efficiency was identified.

The roasting cost works out at approximately $1.22 per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941- 1942 was 32 cents per ton milled or $1.25 per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

Gardner has presented prorated costs for a number of copper-mining companies in tables 63 and 64 of Bulletin 405. In the same bulletin, tables 53 to 62, inclusive, present additional data on cost of producing a pound of copper. Table 57 of this series is reproduced below. Many companies mining ores of the base metals containing precious metals
* 2.2 m (60-89 in) gyratory crushers for ore crushing, at a cost of $20 million. Each crusher has a capacity of 6000 tonnes/h and has its own conveypr system transportin g ore to the Lornex mill
Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.
At the Luikonlahti concentration plant, copper ore from Polvijärvi is crushed weekdays from 6 a.m. until 10 p.m. The C130 jaw is set at 100–120 mm and it crushes some 250 tons per hour. The ore is crushed into finer particles with secondary and tertiary (GP330) cone crusher, aiming to achieve 10mm particle size.
