This process makes use of aqueous (waterbased) solutions to extract and purify copper from copper oxide ores at normal temperatures. This process could include three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching. Crushed ore is loaded into a heap on top of an impermeable layer, at a slight angle.

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

4. Some Terms Lets Have a Look Minerals: A solid element or compound which occurs naturally in the Earth's crust is called a mineral. Ore: A mineral from which metals can be extracted profitably is called a metal ore. Profitable extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal.

What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brassyellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.
