Processing and Production Plant in Copper-gold

AUTHOR: admin       DATE: 26 Apr 2012 05:28:16

Hongxing Machinery is a mining machinery manufacturer that integrates research, development, production and sale as a whole. The main products are crusher, dressing equipment, sand manufacturing equipment and grinding equipment, which are widely used for metallurgy, mine, chemical industry, building materials, coal, refractory material and ceramic, etc. Among these products, the sets of mineral processing equipment, such as the ball grinder, the magnetic separating and flotation equipment, classifing machine and drying machinery, are applicable to process the copper gold that are difficult to process. According to the users' special demands, our Hongxing Machinery provides the project design, process design and purchase program design.

When the content of the soluble copper in the ore stone is low, the cyanide consumption can be increased if the economic situation can afford to. The operation should be done in the low temperature and the low cyanogens quality score because the dissolution rate of copper will notably increase with temperature and the mass fraction of cyanide increasing. In production, in order to control the dissolution rate of copper, subsection dosing and sub-slot dosing are adopted to keep a suitable mass fraction of cyanide in every slot. The gold recovery should be guaranteed and at the same time, the cyanide consumption should be reduced as low as possible. When the copper content in the ore is higher(such as more than 0.3%) and the cyanide consumption is so high that the economic cost is not worthwhile, the floatation can be adopted at the present. some qualified copper concentrates are selected and then tailings are cyaniding to get the gold.

In order to make full use of mineral resource, different leaching methods can be used together when comprehensive recovery is necessary. For example, the dilute sulphuric acid is used for copper leaching firstly and iron replacement method is used to get the copper sponge from the copper sulfate solution. The copper leaching residue whose copper content is reduced will be cyaniding and the gold will be collected. This method also can be used for processing the fine power that contains copper and gold. According to the user's special demands, Hongxing Machinery provides the project design, process design and purchase program design.

Among the gold ore, the copper ore accretes with the gold ore and this gold ore is called copper gold ore. In these copper ores, except a few little copper mine such as chalcopyrite and chrysocolla, most of copper mine, for example, malachite, chessylite and chalcocite, have high solubility in the cyanide solution. When the gold lixiviates through cyaniding, these copper mine with high solubility in the cyanide solution, will scramble for the cyanide and oxygen with the gold so that the dissolution of the gold will be hampered. So according to the copper content in the ore, there should be different processing methods used with the deryer machine. Henan Hongxing Mining Machinery Co., Ltd has an outstanding team and the team will use professional technology to solve all the problems in copper gold and ore beneficiation for you.
