Processing of Complex Materials in the Copper
06/07/2020· Global weighted average of copper concentrate output in a large sample of plants was around 25% copper in 2015 data. There are significant data published on the falling copper ore grades in recent decades, but a factor of concern is that the ore grades in recently operational mines are not over 0.53%, while copper grades in new projects and in undeveloped mines are not over 0.43% copper Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1.

ConRoast MINTEK Welcome to MINTEK
This process produced copper by electric smelting of dead-roasted chalcopyrite concentrate in a 5 m diameter, 2.5 MVA circular AC submerged-arc furnace, using coal as a reductant. (8-11) Only 10 per cent of the smelter output was produced via this process, as the bulk of the plant’s output is based on the re-processing of scrap and residues.19/05/2021· Calculate the sum of all the weighted values to arrive at your weighted average. Example: 7.5 + 15.2 + 16 + 44.1 = 82.8. The weighted average is 82.8%. Using the normal average where we calculate the sum and divide it by the number of variables, the average score would be 76%.How To Calculate Weighted Average in 3 04/03/2021· As you see, a normal average grade (75.4) and weighted average (73.5) are different values.
