Relation to Mining The amount of copper believed to be accessible for mining is 16 billion tons In addition, it is estimated that 700 million tons of copper is available in deepsea nodules Mineralrich nodules of magnesium, copper China, the US, Australia, China, the DR of Congo, Zambia, Mexico, Russia, and Kazakhstan round out the top 10 list of top copper producers And now for some really fascinating copper facts The metals of antiquity – copper Native copper occurs in a variety of ore deposits associated with mafic volcanics and in some sandstones Copper is found as branching sheets, plates, and wires, and as massive pieces In Figure 926, it is in a discontinuous sheet that has partially altered to malachite, copper carbonate9 Ore Deposits and Economic Minerals – MineralogyMinerals other than sulfates formed as postmining deposits as well, but were relatively minor in nature In some cases, the nonsulfate, postmining minerals were also a direct result of the sulfide oxidation, but in reactive environments, such as limestone, which typically caused carbonates to form or elemental copper Post mining minerals of Bisbee ArizonaMining is the extraction (removal) of minerals and metals from earth Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some What is mining?

Copper has been weakly and irregularly reprecipitated in the upper zones of the deposits Secondary sulphides are dominantly chalcocite with minor covellite and rare native copper These secondary minerals occur as fracture infills, coatings on primary sulphide minerals and disseminationsAccording to historians, the Egyptians were mining copper on the Sinai Peninsula as long ago as 3000 bce, although some bronze (copper alloyed with tin) is dated as early as 3700 bce Iron is dated as early as 2800 bce; Egyptian records of iron ore smelting Mining Britannica INVESTMENT OPPORTUNITIES •Seven (7) Strategic Minerals Potential to make Significant GDP ContributionsBitumen, Gold, Coal, Lead/Zinc, Baryte, Iron –Ore and Limestone •Bitumen Resource Belt Spanning through Lagos, Ogun, Edo and Ondo States • Gold Found in alluvial placers and primarily veins in parts of theINVESTMENT OPPORTUNITY IN NIGERIAN MINERALS/ Some of the minerals in the area are limestone, iron ore, base metals (copper, lead and zinc), coal, lignite oil and natural gas, clay, shale, barites, fluorspar, quartz, cadmium, silver and gold The occurrence and distribution of Copper ore in Nigeria mainly around the Benue TroughMINING OPPORTUNITIES IN NIGERIA; COPPER ORE Additionally, today’s mining equipment makes it possible to reduce waste and decrease chemical exposure during all phases of the copper mining process The Basics of Copper Mining and Processing Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production Using today’s compact Copper Mining and Processing: Everything you Need

copper, but mostly occurs in combination with other elements (Figure 2) Native copper is typically found as irregular masses or veins, which fill fractures and other spaces in the earths crust When found in combination with other elements, copper can occur in minerals including copper sulfides (eg, chalcopyrite and chalcocite), copper At least 160 copperbearing minerals have been identified in nature; some of the more familiar minerals are chalcopyrite, malachite, azurite, and turquoise Copper consumption changes from 1980 through 2008 for India, the United States, China, and the rest of the worldUSGS Mineral Resources Program Copper—A Metal for Most copper production in Zambia occurs in an area known as the "Copperbelt"' Ten major mines are currently in production in the area,12 which is also the site of substantial prospecting and preparation operations To a much lesser extent, Zambia produces other minerals13 Cobalt, a byproduct of copper production, is a growing export LargeMining Legislation and Mineral Development in ZambiaMining is the extraction (removal) of minerals and metals from earth Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some What is mining? Mongabay Copper sulfides such as chalcopyrite (CuFeS 2), covellite (CuS) and chalcocite (Cu 2 S) are the most abundant, and thus mainly used, minerals in the copper mining industry worldwide These metallic sulfides have semiconductor properties and they can be activated by sunlight Some of them have been used as photocatalysts for water purificationPhotocorrosion of copper sulfides: Toward a solar
