Copper ore is extracted using two basic methods of mining - open pit or underground mining. 3. Processing of Copper Ore. The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps. 4. Beneficiation of Copper Ore

We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. 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.

extraction/electrowinning plant Ranchers leached run of mine copper oxide ore (> 0.5% Cu) placed in a sealed canyon in 20-foot layers (heaps) by distributing dilute sulphuric acid over the fresh ore via spray emitted from needle valves with pipes and needle valves placed to ensure complete coverage of the ore. New heaps were built over old heaps.

Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon. These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

Mining. Although large copper deposits are mined by open-cut methods in many of the major producing countries, most of the copper ore produced in Australia comes from underground mines. The traditional method used at most mines involves the ore being broken and brought to the surface for crushing.

view moreSulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue.

The Mine ore is transported to the crushing plant where it is crushed to a size appropriate for the grinding process and then conveyed to the concentrator. After a series of runs through furnaces, where non-copper elements are burned off or separated, the result is a 99 percent pure molten copper.
view moreThe four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...

The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the Earth's crust, or noble ...

Despite this early production, most copper used in the United States was imported from Chile until 1844, when mining of large deposits of high-grade copper ore around Lake Superior began. The development of more efficient processing techniques in the late-1800s allowed the mining of lower-grade copper ores from huge open-pit mines in the ...
