    Extraction Of Copper | Mining, Concentration, Smelting | …

    Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulphides.The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. ...Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops.Read more

    Copper Smelting Process

    Copper ore typically contains only about 0.6% of the actual copper mineral, the most common ore mined being chalcopyrite. The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90% of the ore used in smelting.Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in largeRead more

    The Mining Process – Waihi Gold

    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 ...Underground mining is used when the copper ore is not near the earth's surface. Miners dig a shaft into the ore deposit vertically or a horizontal tunnel (or adit) in order to do this. Mining then follows the vein of ore and the underground mine develops.Read more

    How copper is made

    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 s allowed the mining of lower-grade copper ores from huge open-pit mines in the western United States.Following are the list of minerals that serve as copper ores in the copper mining process: Name. Formula. % Copper. when pure. Chalcopyrite. CuFeS 2. 34.5. Chalcocite.Read more

    Newmont Corporation

    There are two types of mine designs for mineral mining: surface (open pit) and underground. Surface Surface mines are generally preferred if the ore body is relatively shallow and uniform, and are made by digging into the Earth’s surface one layer at a time. The finalMining - Mining - Prospecting and exploration: Various techniques are used in the search for a mineral deposit, an activity called prospecting. Once a discovery has been made, the property containing a deposit, called the prospect, is explored to determine some of the more important characteristics of the deposit. Among these are its size, shape, orientation in space, and location with respect ...Read more

    ICMM & Operating mines

    Surface mining involves the stripping (removal) of surface vegetation, soil and (if necessary) layers of bedrock to reach buried ore deposits. Common techniques for surface mining include: Open-pit mining and quarrying : The recovery of ore from a progressively wider and deeper hole in the ground using large vehicles to haul the ore from the pit to the processing facility. · Either through strip-mining or blasting, raw ore is obtained for extraction of copper. Heap Irrigation The ores obtained from mining are crushed and piled up to 10 meters high atop plastic irrigation pads, whereupon water seeded with acid, called the lixiviant, is irrigated through the heaps and collected (Fig. 2).Read more
