The major producers of copper ore are Chile, USA and Australia, the vast majority of the ore coming from open pit mining. In open pit mining the layers of soil and vegetation seam are scooped away until the copper bearing ore is exposed. This is removed by blasting, the resulting ore collected and transported to the ore processing plant.

Los Bronces is an openpit coppermolybdenum mine located in the Andes, 65 kilometres northeast of Santiago at 3,500 masl. Infrastructure includes copper sulphide ore treatment plants, a 56kilometre slurry pipeline, copper and molybdenum floatation plants and two solvent extraction electrowinning (SXEW) plants for the lowgrade ore dump leaching process.
ized in all phases of copper production. Both machine and human productivity have increased dramatically. This chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or solvent extraction and electrowinning. The chapter begins with an overview of the history of cop
Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called 'hydraulic mining') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains.

Mar 02, 2016· Openpit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining .
Equipment plays an important role in open pit mining industry and its cost competence at efficient operation and maintenance techniques centered on reliability can lead to significant cost reduction. The application of optimal maintenance process was investigated for minimizing the equipment breakdowns and downtimes in Sungun Copper Mine.
Open pit mining at Aitik. Aitik is a single open pit divided into a southern section, where mining reached a final depth of 250m, and a northern area where mining is proceeding towards an ultimate 400m. The strip ratio is just below 1:1 – per month of waste and per month of ore in mid2004.
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
the Australian mining industry invested in gold extraction process technology, which transformed the industry. Given the right levels of investment, significant gains should be possible through innovating mining and processing methods, perhaps in conjunction with original equipment manufacturers (OEMs). 3 . o counte ra ct ri ing re a l a g s
Openpit mining, smelting, and refining of copper in Utah Search Britannica ... Utah, copper concentrate is turned into metal in a process called smelting. Smelting heats up the concentrate at very high temperatures and removes most impurity elements. ... Most of the world's production of copper is used by electrical industries.
Toxic chemicals used in mining include: cyanide, sulfuric acid, and solvents for separating minerals from ore. nitric acid. ammonium nitrate and fuel oil ("ANFO") used in blasting tunnels. heavy metals such as mercury, uranium, and lead. gasoline, diesel fuel, and exhaust fumes from vehicles and equipment.
Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc. Stopes are large openings or rooms connected by tunnels in which miners drill and blast the ore. A pillar or wall is left between each room (stope) to prevent the mine from collapsing.
