slide 2 of 7. Mining for Copper Bearing Ore There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment. The major producers of copper ore are Chile, USA and Australia, the vast majority of the ore coming from open
A Brief History of Mining The Advancement of Mining
History of Mining Technology. Mining shafts were dug out by hand, and the entire process was very lengthy. Eventually, people began using fire to clear tunnels and reach greater depths at a faster rate. During the 1600s, miners started using explosives to break up
Mining Technology in the Nineteenth Century ONE
Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from on the ground reconnaissance by prospectors to remote sensing techniques such as satellite imagery.

Sustainable Development Mining Environmental Impact
An estimated 990 million tons of ore were mined to produce about 9 million tons of copper in 1990. Mining and mineral processing is one of the largest users of energy worldwide, and therefore contributes heavily to air pollution and global warming. One of the most energy intensive mineral industries is steel making.

Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining
From Ore to Finished Product Copper
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper tin alloy) about 3000 BC, was the first engineering material known to man.

Development of an underground metal mine copper mining
Development of an underground metal mine. When stoping, some ore has to be left in situ, for example, in the pillars and sill pillars for support of levels and in the rib pillars for support of winzes and raises. This loss of ore is naturally more with shorter level intervals than when the level interval is more.
