Working in mining is risky business. Earlier this year, a man was killed in an accident at a copper mine in Australia. Another accident at a coal mine in southwest China claimed 22 lives. In fact, China has some of the most dangerous mines in the world, and authorities have scrambled to try to enforce safety rules.
Copper. Malleable, resistant to corrosion and high temperatures, recyclable and blessed with the best electrical and thermal conductivity of any commercial metal, copper is highly valued for its application in power transmission and generation, building wiring as well as practically all electronic equipment, including mobile phones and television sets.
The Zinc Mining Process. Once it's removed from the earth, the concentrate is roasted at a temperature of 950 degrees Celsius, causing zinc, sulfur and iron oxidization. After the zinc and iron oxides are reduced to powder form and leached with diluted sulfuric acid, the solution is neutralized and contaminants are removed via filtration.
Jan 05, 2015· The main data bands that mining companies have to worry about are maintenance and asset information, geological and geospatial, environmental, process control and automation, production and throughput/tonnage and then the usual financial, supply chain.
Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
The Chuquicamata mine's smelting process involves two stages: a smelting stage and a conversion stage. The smelting stage converts copper concentrate, with 29 to 33 percent purity, into a high temperature liquid mixture with a higher copper purity depending on the equipment used: a flash furnace (FF) or one of the teniente converters (TC1 ...
