Straight gravity concentration of this ore, using the flowsheet shown, would result in a mixed gold tungsten concentrate containing much sulphide which is not desirable for marketing. Consequently, it is evident that other concentration processes must be incorporated in the flowsheet to produce separate marketable concentrates of tungsten and gold.
Ore undergoes primary crushing at the mine, before being delivered by ore passes to the mill complex for further crushing, grinding and flotation. Grasberg's milling and concentrating complex is the largest in the world, with four crushers and two giant semi autogenous grinding (SAG) units processing a daily average of 240,000 tonnes of ore in
Applications of Spiral Separator. Hengchang mining spiral separator has been used in to classify the granularity 0.3 0.02 millimeters fine grain like iron, tin, tungsten, tantalum niobium, gold ore, coal mine, monazite, rutile, zircon and other metals. The non metallic minerals which have a big enough specific gravity difference.
Gold mining companies are active on all continents on earth. This wide geographical distribution in production means that interruptions in any single region due to local political or social matters are unlikely to have a large impact on the global gold supply.
