COPPER ORE STORAGE. Many mills store not only the coarse ore but also the fine ore in open stockpiles using ore as the side walls and drawing the live ore from the center. During prolonged periods of crusher maintenance the ore walls can be bulldozed over the ore feeders to provide an uninterrupted supply of ore for milling. GRINDING COPPER ORE
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 (ndida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year.

The entire output of these mines was lowgrade milling ore. The openpit mining of porphyry copper deposits was adopted worldwide. In the 1910s and 1920s, copper mills adopted the froth flotation method, which had been developed in Australia.
Copper is used in many different industries, including building construction, transportation, electronics and consumer goods. Minerals are concentrated in specific types of geologic formations (ore bodies), which are where mining takes place. These ore bodies may already contain naturallyoccurring radioactive materials (NORM).

The 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 directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger ...
Mining; Milling; Smelting; Refining; Milling. Crushing The haul trucks carry the ore out of the pit along a haulage road with a slope of no more than about nine percent. They dump the ore into a gyratory crusher which reduces the ore to eight inches or less — about the size of soccer balls. ... Only then are the copper minerals broken free of ...
