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.

1.1.3.2 Placer mining 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. Because placer mining often occurs within a streambed, it is

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 western United States.
Copper ore divides into ore sulfide,ore oxide and mixing ore according to its oxide rate. The main process for copper ore is flotation, for refractory mixed copper ore and refractory oxide ore, normally use hydrometallurgy process. Online consultation Ask for quotation

Mining produces ores with less than 1 percent copper. Concentration isplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals,pressed air, separates the ore into fractions. Depending upon the chemicals used, some minerals float
