  • mining. the ore is removed from the ground in either open pit or underground mines. underground sinking a vertical shaft into the earth to reach the copper ore and driving horizontal tunnels into the ore.
  • grinding. the ore is crushed, then ground into powder. concentrating. the ore is enriched using a process called froth flotation. unwanted material (called gangue) sinks to the bottom and is removed.
  • roasting. this is where the chemical reactions start. the powdered, enriched ore is heated in air between 500°c and 700°c to remove some sulphur and dry the ore, which is still a solid called calcine. smelting with fluxes. a flux is a substance which is added to the ore to make it melt more easily. the solid calcine is heated to 1200°c and melts. some impurities are removed forming a matte (a mixture of liquid copper and iron sulphide).recovery of copper by solution mining methodsare introduced to the copperbearing ores, causing dissolution of soluble copper minerals (table 1) remaining in the leached cap and underlying enrichment blanket. this produces a pregnant solution that is collected and transferred to surface processing facilities, where the copper is recovered. table 1: common soluble copperbearing minerals an ore contains 5% copper, how much ore is required to obtain x is the amount of ore you need. 5% or 5/100 of that ore is copper so [math]x 92;times 92;frac{5}{100} = 400 g.[/math] you do the math.
