Colombia Gold Crushing Plant Nigeria
Colombia has rich natural resources, like coal, oil, emerald and so on. Among them, the coal reserves in Colombia are about 24 billion tons, ranking the first place in Latin America. Our engineer designed a complete coal crusher plant for a Colombia customer in the beginning of year 2014. In this article, we mainly talk about this coal crusher plant design.
To extract the gold from gold ore, customers need to crush gold stone into a fine dust. Then use other equipments to process gold ore dust. Gold crushing plant is also used as the primary crusher for crushing gold ore in Colombia. Jaw crusher is the most used gold mining machine for crushing ore. Small capacity jaw crusher is widely used in crushing gold ore. Gold mobile crusher is the newly type of gold mining machine for gold crushing. SBM Company can offer the high efficient and low cost project plants for the client. Gold ore mobile crusher is the best choice as a gold mining machine. It is easy to operate and easy to move from one gold mine to another one.
Raw Gold Crushing Plant Process
Large raw gold ore are fed to the jaw crusher evenly and gradually by vibrating feeder through a hopper for primary crushing. After first crush, the material will transferred to cone crusher by belt conveyor for secondary crush; the crushed gold ore stone will then transferred to vibrating screen for separating. After separating, the parts that can meet standard will be transferred away as final products, while the other parts will be returned to cone crusher, thus forming a closed circuit. Size of final products can be combined and graded according to your specific requirement.
In Colombia, During gold ore processing, Grinding mill plays a very important role for ground ore sizing. After primary crushing, the gold ore is fed into the SAG mill along with water, and then convoyed to ball mill for further Grinding which reduces the gold ore to slurry. The gold ore grinding mill will grind ore minerals into fine powder or ultrafine powder so that the leaching and smelting process can go smoothly. Ball mill always the best choice in gold ore grinding. SBM Company company has been amongst the pioneers for many years in the design and application of gold crushing plant and gold ore grinding. There are two kinds of ball mill, grate type and overfall types due to different ways of discharging material. Customer can choose a suitable one according to different requirement.

Colombia gold mining mobile crusher
Mobile crushing Plant, which can also be called mobile crusher or portable crusher,portable crushing plant, is a new type of crushing plant. Some crushing machines and screening machines can be installed onto the movable platform of the mobile construction station, which greatly improves the flexibility of the equipment.
In some areas where fixed production line is not convenient to set up, but mobile crushing plant will be very convenient.For example, when processing construction waste, mobile crusher can be placed in one place, and after finishing the crushing task, it can be removed to another place immediately. For this reason, mobile crushing plant can also be called mobile construction station or construction waste disposal crushing station.
gold mining mobile crusher Application
Mobile Crushing Plant is widely used in mine, building material, highway, rail way and hydropower industries, etc. The crushing and screening processes can be finished at one time to produce the required size and capacity.
Gold Processing Plant
The ore is ground into 75 microns particle size with passing rate is 80% (D80), the unrecovered gold from the grinding circuits are directed to the leaching plant and dissolved in an aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed onto coarse granules of activated carbon directly in the pulp in the so-called Carbon-In-Leach process (CIL). The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated out onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before it is mixed with ﬂuxes and melted. Finally, the melt is poured into a cascade of molds where gold is separated from the slag.
Gold mine in Colombia
Colombian gold mine are main placer gold ores and gold lode ore. The placer gold ores are mainly distributed in the following seven areas:
(1) Garcia - Bagre (Antioquia Province in the northwest), placer gold producing areas in the country. Gold deposited in the Tertiary and modern alluvial deposits, the minerals are native gold, platinum and heavy mineral reserves of 155 tons.
(2) Choco region, Art Colorado River and the San Juan River Basin area of sand gold and platinum mining, the two river basins alluvial deposits from the cordillera, where native gold veins due to the hot and humidclimate and the chemical reaction and weathering.
(3) Barbacoas in Nariño Pacific coast, there are three types of placer gold ores in the late Tertiary to modern deposition.
(4) Saldanha, the main producing areas of Saldanha River Basin.
(5) San Miguel - la sierra, located in the province of Antioquia.
(6) Amalfi - Arnold, the Late Tertiary placer gold ores.
(7) Guyana region, mostly small-scale placer gold ores.
The gold lode ore are mainly located in the East, in Antioquia, Cordillera, Cauca - romeral, Ibague - loosely Weite Si and other six regions.
Gold beneficiation process in Colombia
Because of the nature of the various types of Columbia gold ore is different from methods used by different dressing, but the commonly used gravity concentration, flotation, amalgamation, cyanidation, and the resin slurry method in recent years, CIP adsorption, the new heap leaching of gold process. For certain types of ore, of gold is often a joint process.
