This is used to make sulfuric acid via the Contact Process. An overall equation for this series of steps is: 2CuFeS2 + 2SiO2 + 4O2 → Cu2S + 2FeSiO3 + 3SO2 (1) (1) 2 C u F e S 2 + 2 S i O 2 + 4 O 2 → C u 2 S + 2 F e S i O 3 + 3 S O 2. The copper (I) sulfide produced is converted to copper with a final blast of air.

2018.2.20 Copper is found across the Earth’s surface, mainly as copper minerals or in mixed ores with other metals like zinc and lead. It is primarily mined through open-pit or underground mining techniques. Open-pit mining, which accounts for approximately 90% of copper production, extracts ores near the earth’s surface via graduated steps that lead

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings.

Primary production uses about 170 x 10/sup 12/ Btu total energy annually (about 100 x 10/sup 6/ Btu/ton pure copper produced from ore). Mining and milling use about 60% of the total consumption, because low-grade ore (0.6% copper) is now being mined. Most copper is extracted by smelting sulfide ores, with concomitant production of sulfur ...

Mineral processing can involve four general types of unit operation: 1) Comminution – particle size reduction; 2) Sizing – separation of particle sizes by screening or classification; 3) Concentration by taking advantage of physical and surface chemical properties; and 4) Dewatering – solid/liquid separation. In all of these processes ...
