The concentrate grade (g / T) = concentrate gold content (g) / concentrate quantity (ton) Concentrate yield: Refers to the percentage of ore concentrate output quantity, it is a reflection of the quality index of mineral processing plant.
In theory, most of the pyrite tailings can be discharged into cyclones, however, because it has even had body and layer of the transfer function and part of the pyrite, gangue minerals and the sulphur mineral can also enter in copper concentrate. Priority flotation chalcopyrite mine sulfur. We usually float copper, and float sulfur.
The flotation circuit produces a per cent Cu concentrate at 91 per cent recovery. Concentrate management The plant concentrate produced in the flotation circuit is deaerated using froth busters and thickened in a high rate thickener.

Nifty is an operating underground copper sulphide mine with an associated copper concentrator. Site infrastructure is extensive, including a powerhouse, camp and airfield. Processing of sulphide copper ore is by conventional comminution, grinding and flotation to produce a clean copper concentrate.
Coppergold concentrates produced at Robinson are transported by truck from the mine site about 210 km to East Wendover, Utah. The concentrate is then railed to west coast port facilities for sea transport.
The most commonly mined type of copper deposit, porphyry copper, is found . copper mineral and the type of equipment, pyrometallurgical recovery may take . multiple brick hearths, however, the copper concentrate moves from the top of the The use of large flotation cells has improved concentration process efficiency.
Namibia Custom Smelters treats complex copper concentrates. At the time of the research, three furnaces were in operation namely, the Top Submerged Lance Furnace, the reverberatory furnace and the converters. All these three furnaces produce fayalite slag as a byproduct. The slags
in mill feed. Their impact on final concentrate fluorine levels is entirely dependent on the flotation process response of each of these minerals, and is in essence the subject of this paper. The fluorine content of Ok Tedi copper concentrates varies typically from 250 • 900 ppm in concentrates that are sent to various smelter customers.
