Khetri is situated at the foothills of the Aravalli Range, which hosts copper mineralization, giving rise to a 80 km long metallogenetic province from Singhana in the north to Raghunathgarh in the south, popularly known as Khetri Copper Belt. The belt comprises of tightly folded Proterozoic metasediments that rest over basement gneisses and is a part of the North Delhi fold belt. Prominent deposits of the belt are: Khetri, Kolihan, Banwas, Chandmari, Dhani Basri, Baniwali Ki Dhani (Neem Ka Thana, Rajasthan). Other deposits are: Dholamala, Akwali, Muradpura - Pacheri (Jhunjhunu, Rajasthan), and Devtalai (Bhilwara, Rajasthan).

Regular mining ceased in this area by 1872. With the advent of 20th century, the geologists of Geological Survey of India. Indian Bureau of Mines undertook explorations. Development of Khetri Mine was started by National Mineral Development Corporation (NMDC) and the project was handed over to HCL in 1967 when HCL was formed. Subsequently, smelting and refining facilities were added.

Khetri comprises of Khetri town and Khetrinagar. Khetri town was founded by Raja Khet Singhji Nirwan, and Khetrinagar, which is about 10 km away from Khetri town, is developed and maintained by Hindustan Copper Limited.

Cuprumis Latin language, it is also known as well know mineral copper. Copper is one of the world's most important industrial minerals; and Africa is an important world producer. While output is traditionally dominated by Zambia, South Africa and Congo, many African nations contribute to copper production.

Mining in South Africa has been the main driving force behind the history and development of Africa's most advanced and richest economy. South Africa is endowed with minerals resources, such as gold, diamond, coal, copper etc. Copper is one of important minerals in South Africa. Cuprum mining in South Africa is operated by open pit and underground mining methods.

Surface cuprummining requires extensive blasting as well as rock, soil, vegetation, and overburden removal to reach lode deposits. Benches are cut into the walls of the mine to provide access to progressively deeper ore as upper-level ore is depleted. Copper ore is removed from the mine and transported to beneficiation plants for milling and concentrating. The concentrate is then smelted and refined. Open-pit mining is the primary domestic source of copper.

Underground mining entails sinking a shaft to reach the main body of ore. Drifts or passages are then cut from the shaft at various depths to access the ore, which is brought to the surface for beneficiation. While underground mines do not create the volume of overburden associated with surface mining, some waste rock must still be brought to the surface for disposal. Waste rock may either be returned to the mine as fill or put in a disposal area.

The copper ore extracted from the mine must be processed by mining plant and concentrated by beneficiation equipment. The valuable minerals like chalcopyrite are inter-grownwith gangue. Therefore, in the first step in cuprum mining plant in South Africa, the lumpy ore is crushed and milled into fine particles and prepared for further mining operation.Copper mining plant in South Africa for sale includes crushing plant, grinding mill, vibrating screen, separation machine, quarry plant etc.

The primary crusher in copper crushing operation is jaw crusher. Typical equipment for crushing to about 20 cm is gyratory crusher, cone crushers and impact crushers. Then wet grindingin grinding mills takes place. Size classification takes is performedin cyclones. In the next step of mining plant, valuable minerals and gangue are separated by frothflotation of the ore pulp, which exploits the different surface properties of the sulfidic copper oreand the gangue.

In open pit copper mining operation, crushing is the first processing stage. Copper ore crushing may be performed in two or three stages. Primary crushing circuit consists of crushers, feeders, dust control systems, and conveyors used to transport ore to coarse ore storage or further crushing plant. Primary crushing is generally processed by a jaw crusher or gyratory crusher, since these units can handle larger rocks.

The feed to primary crushing is generally run-of-mine ore, which is reduced from large pieces to smaller pieces. Secondary and tertiary crushing usually is performed in surface facilities in cone crushers, although impact crusher or hammer crusher are sometimes used.

geologic setting, genesis and transformation of sulfide deposits in the northern part of khetri copper belt, rajasthan, india an outline | springerlink

The present study is confined to the northern part of the Khetri copper belt that extends for about 100 km in northern Rajasthan. Mineralization is more or less strata-bound and is confined to the garnetiferous chlorite schist and banded amphibolite quartzite, occurring towards the middle of the Proterozoic Delhi Supergroup. Preserved sedimentary features and re-estimation of the composition of the pre-metamorphic rocks suggest that the latter were deposited in shallow marine environment characterized by tidal activity. Cordierite-orthoamphibole-cummingtonite rock occurring in the neighbourhood of the ores is discussed, and is suggested to be isochemically metamorphosed sediment. The rocks together with the ores were deformed in two phases and metamorphosed in two progressive and one retrogressive events of metamorphism. Study of the host rocks suggests that the maximum temperature and pressure attained during metamorphism are respectively 550600C and < 5.5 kb. Principal ore minerals in Madan Kudan are chalcopyrite, pyrrhotite, pyrite and locally magnetite. In Kolihan these are chalcophyrite, pyrrhotite and cubanite. Subordinate phases are sphalerite, ilmenite, arsenopyrite, mackinawite, molybdenite, cobaltite and pentlandite. The last two are very rare. Gangue minerals comprise quartz, chlorite, garnet, amphiboles, biotite, scapolite, plagioclase and graphite. The ores are metamorphosed at temperatures > 491C. Sulfide assemblages are explained in terms of fS 2 during metamorphism. Co-folding of the ore zone with the host rocks, confinement of the ores to the carbonaceous pelites or semi-pelitic rocks, strata-bound and locally even stratiform nature of the orebodies, lack of finite wall rock alteration, metamorphism of the ores in the thermal range similar to that for the host rocks, absence of spatial and temporal relationship with the granitic rocks of the region led the authors to conclude that the entire mineralization was originally sedimentary-diagenetic. Any loss of primitive features and development of incongruency are due to subsequent deformation and metamorphism to which the ores and their hosts were together subjected.
