Get PriceFlotation process Sulfur makes up a substantial portion of the mineral in the lead ore galena which is called lead sulfide The flotation process helps in bringing out the sulfur bearing portions of the ore since it also contains the valuable metal The finely crushed ore is diluted with water and then poured into a tank
Get PriceThe Process of Froth Flotation The froth flotation method used in the gold mining mainly includes After washing and classifying the mineral is mixed evenly by agitation tank drum and sent to the flotation machine The goldmine generally uses sodium carbonate as the regulator so that the gold is floated
Get PriceGold cyanidation also known as the cyanide process or the MacArthur Forrest process is a hydrometallurgical technique for extracting gold from low grade ore by converting the gold to a water soluble coordination complex It is the most commonly used leaching process for gold extraction Cyanidation is also widely used in the extraction of silver usually after froth flotation
Get PriceMineral Flotation Flotation has been at the heart of the mineral processing industry for over 100 years addressing the sulphide problem of the early 1900s and continues to provide one of the most important tools in mineral separation today The realisation of the effect of a minerals hydrophobicity on flotation all those years ago has
Get PriceFroth flotation is the process of selectively separating hydrophobic materials from hydrophilicity when first used in the mining industry it was one of the greatest enabling technologies of the 20th century It is described as the most important single operation for the recovery and purification of sulfide ores
