    The Platsol™ process was originally developed in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and subsequently tested on other PGM concentrates. This process involved codissolution of base metals (copper and nickel), gold, and PGMs via addition of chloride to the autoclave. Grinding the ore with ceramic rather than iron balls was

    His "Bradford Ore Separator," patented 1853 and subsequently improved, was used to concentrate iron, copper and lead-zinc ores by specific gravity, but lost some of the metal as float off the concentration process. The 1886 patent was to capture this "float" using surface tension, the first of the skin-flotation process patents that was eclipsed by oil froth flotation. It is uncertain if his

  • Surface chemistry investigation of froth flotation

    01.01.2021· In the mineral processing industry, lead-zinc sulfide ores are usually processed by froth flotation to enrich the purpose minerals. Flotation is a complex process, and the selective separation of minerals depends on the balance between the hydrophilic species and hydrophobic species on the mineral surface,.

    In the Isasmelt process, a gas or air lance is brought in through the top of a furnace and its tip submerged in the sulfide concentrate. A blast from the lance produces a turbulent bath in which the concentrates are oxidized to produce a high-lead slag. This slag is tapped continuously and transferred to a second furnace, where it is reduced with coal. Crude lead and slag are tapped continuously from the

    Often we hear that copper concentrates have contaminants which affect the incomes to be obtained by commercialization. Well, one of the worst contaminant is bismuth because is difficult to remove during smelting process and the metallic copper to be obtained at the end of the process will be brittle and consequently its mechanical properties will be very bad. Ergo, the objective is focused to

  • Lead Mining Concentration process, flotation, filtering

    Flotation 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. The mixture of

    Before lead concentrate can be charged into traditional blast furnaces for smelting, it must be roasted to remove most of the sulfur and to agglomerate further the fine flotation products so that they will not be blown out of the blast furnace. Various fluxing materials, such as limestone or iron ore, are mixed with the ore concentrate. The mix is spread on a moving grate, and air is blown
