The name "zinc" only came into general use in the 17th century following rediscovery of the material. As zinc only ever occurs in Nature in the form of compounds, it was initially produced from carbonate of zinc, a zinc salt. Zinc was found to be especially suitable for alloys with other metals and was therefore first of all employed to make coins.
The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today''s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it''s roasted, which helps to convert sulfides to oxides.
How Bitcoin Mining Works. Where do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn''t have a central government. With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange.
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.

We mine and process zinc and lead ores in the key mining regions of Australia, South America, Kazakhstan and Canada. And, we smelt and refine zinc and lead at processing operations in Australia, Canada, Spain, Italy, Germany, the UK and Kazakhstan. We also source and recycle zinc and lead materials in Europe and North America.
Uses. The primary use of zinc is in galvanizing, which protects iron and steel from rusting. However, zinc can also be alloyed with other metals and used for die casting into shapes such as door handles, alloyed with copper to make brass, and alloyed with copper and tin to make bronze.
