Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are See for further information on the leaching process.

Zinc reserves. Mining resources are estimated at a level of 220 million tons of currently exploitable zinc ore reserves. Annual world consumption of zinc is at present 9.7 million tons. Since recycling accounts for about 39% of zinc consumption, zinc reserves are depleted at a yearly rate of 5.9 million tons.

Zinc is a bluish-white, lustrous metal with the chemical symbol Zn. Its main ore mineral is sphalerite (ZnS). Some of its uses are for galvanizing (plating thin layers of zinc onto iron or steel to protect from corrosion), production of brass (combination of zinc and copper), and coloring in rubber and paint.

This mining process was in fact risky in earlier days. Several tunnels caved in trapping and slaughtering miners. Ore was the material which was frequently mined in this manner. It's a rock with minerals in it. In early period miners threw away the silver, copper, and further minerals that they discovered along with gold that they were looking for.

Background. During the era of the Roman Empire, people used zinc to alloy copper into brass for weapons. In this crude process, the zinc was captured by the copper during the heating of the ores, though little was realized at the time about the importance of zinc in metallurgy.

Zinc ores are obtained by many mining techniques, ranging from open-pit mining to the normal underground methods. The most common underground method of ore extraction is cut-and-fill stopping, in which tunnels are dug to moderate depths, branching away from the mine holes.

The primary source of aluminum is an ore known as bauxite. An ore is any naturally occurring solid material from which a metal or valuable mineral can be obtained. In this case, the solid material is a mixture of hydrated aluminum oxide and hydrated iron oxide. Hydrated refers to water molecules that are chemically bound to the two compounds.

8 6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

User rating 4.5/5Since iron and silver are usually associated with lead-zinc ore, they strongly contribute to the impact of metal depletion. Although a few copper elements exist in lead-zinc ore, the application of copper sulfate in beneficiation process results in the metal depletion corresponding to copper.

Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.
