Copper oxide needles | Article about copper oxide needles by The Free ...

Copper oxide ores are usually treated by a different process, called leaching, in which the copper in the ore is dissolved in a leaching solution (usually dilute sulfuric acid); pure copper is recovered by electrolysis. Alternatively, the solution is treated with iron to precipitate the so-called cement copper, which is impure. Importance and Uses

copper ores. An ore is a rock that contains enough valuable mineral to make it worth mining. In the case of copper, it pays to extract if there are about 2 kg of copper per 1.000 kg of ore (0,2%). Copper minerals can be found in more than a hundred varieties, although only a few are widely used for copper.

lead ore | lead concentrate | Galena - Arsenic metal

Most ores contain less than 10% lead. Ores are crushed and concentrated by froth flotation typically to 70% or more. Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silicates of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a coke-fired blast furnace.

The froth is skimmed off and the resulting lead sulphide concentrate is dried. During this process, the ore, which may contain only 5% lead, is upgraded to a concentrate with 50% or more lead. At Broken Hill, concentrate grades average about 70% lead, mainly because the relatively coarse grain of the ore allows excellent recovery of lead sulphides.
