them. this section introduces the different techniques used to extract or remove these resources. see full list on courses.lumenlearning.com miningis the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner. ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. mining is required to obtain any material that cannot be grown through agricultural processes, or created artificially in a laboratory or factory. mining in a wider sense includes extraction of any nonrenewable resource such as petroleum, natural gas, or even water. mining of stone and metal has been done since prehistoric times. modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final reclamation of the land after the mine is closed. the nature of mining processes creates a potential negative impact on the environment both during the mining opera see full list on courses.lumenlearning.com environmental effects environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. in some cases, additional forest logging is done in the vicinity of mines to create space for the storage of the created debris and soil. contamination resulting from leakage of chemicals can also affect the health of the local population if not properly controlled. extreme examples of pollution from mining activit waste ore mills generate large amounts of waste, called tailings. for example, 99 tons of waste are generated per ton of copper, with even higher ratios in gold mining. these tailings can be toxic. tailings, which are usually produced as a slurry, are most commonly dumped into ponds made from naturally existing valleys. these ponds are secured by impoundments (dams or embankment dams). in 2000 it was estimated that 3,500 tailings impoundments existed, and that every year, 2 to 5 major failures and openpit mining after mining finishes, the mine area must undergo rehabilitation. waste dumps are contoured to flatten them out, to further stabilise them. if the ore contains sulfides it is usually covered with a layer of clay to prevent access of rain and oxygen from the air, which can oxidise the sulfides to produce sulfuric acid, a phenomenon known as acid mine drainage. this is then generally covered with soil, and vegetation is planted to help consolidate the material. eventually this layer will erode, see full list on courses.lumenlearning.com answer

processing methodsthe 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

function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. usually, primary crushers are sized by the ability to accept the largest expected ore fragment. jaw crushers are usually preferred as primary crushers in small installations due to inherent mechanical simplicity and ease of operation of these machines. additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. the primary crushermust be designed so that adequate surge capacity is present beneath the crusher. an ore stockpile after primary crushing is desirable but is not always possible to include in a compact design. many times the single heaviest equipment item in the entire plant is the primary crusher main frame. the ability to transport the crusher main frame sometimes limits crusher size, particularly in rem see full list on 911metallurgist.com the screen or screens in a small crushing plant should be oversized and of the fourbearing type if possible. installed screens should be standard sized and, if multiple screens are used, all screen panels should have the same dimensions. the screen layout should be such that screen decks are readily accessable. screens should be located for optimum visibility and required chutes should be designed with the maximum open area possible. to minimize the height of the undersize chute, discharge conveyors should be oriented along the long dimension of the screen. the slope of the discharge conveyor should be as nearly parallel to the slope of the screen as is possible. the utilization of rubber top decks should be considered due to the longevity of this material. the use of tall chutes should be avoided or, if absolutely necessary, should be provided with dead beds and cleanout ports. spare screen panels should be provided with the original equipment since considerable time can lapse bet see full list on 911metallurgist.com although design calculations may indicate overcapacity, no conveyor in any crushing plant should be less than 0.5 meters wide and, in actuality, it is best to standardize on a minimum belt width of 0.67 meters throughout the crushing system. design should be such that conveyor troughing and return idlers can be lubricated from one side. barely are small conveyors designed and manufactured with walkways on both sides of the belt. in smaller installations some designers prefer to specify permanently selflubricated idlers. the design of tail pulleys should be oriented toward ease of cleanup. the lowest point of any belt should be at least 0.6 meters above the floor. rock deflectors or plows located immediately in front of tail pulleys above the returning belt can serve to prevent rooks from cycling between the belt and pulley thereby increasing belt life. in tunnels, beneath stockpiles, and in other locations below grade, provisions must be made to include the cleanup sumps and pumps see full list on 911metallurgist.com fine ore bins must be sized to provide the surge capacity required for continuous operation of the flotation concentrator. the usual configuration for plants processing 500 metric tons per day or less is a single cylindrical bin, 10 meters in diameter and 10 meters high, fabricated of rolled plate which is welded or bolted on site. this type bin is discharged through a slot which is approximately as long as the diameter of the bin. under no circumstances should the discharge slot in the bin be less than 0.6 meters wide. a 1 meter wide slot the length of the bin discharged by a 1.25 meter wide variable speed conveyor has proven to be an excellent system. even though this installation appears to be overdesigned, it will pay for itself the first time that the ore becomes wet and/or sticky. if the crushing plant and fine ore bin are in close proximity and if the typography is favorable, one conveyor can be eliminated if the finishing screen is located atop the bin (see figure 3). in thi see full list on 911metallurgist.com
