Know MoreJan 01, 2017 · Base metals such as copper, lead, and zinc are mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an ore. Flotation process is widely used to separate these minerals in sulfide ores [1]. A wide range of chemical reagents are used in the flotation process to separate the different minerals.
Know MoreThe Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or darkcolored streaks, and an igneous origin.

Know MoreIn the United States galena (a lead sulfide ore) is mined in southern Missouri, with some ore coming from the western states. The ore is concentrated by the flotation process flotation process, in mineral treatment and mining, process for concentrating the metalbearing mineral in an ore. Crude ore is ground to a fine powder and mixed with
Know MoreOre concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide
Know MoreFor example, Broken Hill ore contains lead sulfide (galena), and zinc sulfide (sphalerite). In the first flotation stage, galena is rendered hydrophobic ("water rejecting") with an organic collector such as xanthate, while sphalerite is kept from floating by the addition of zinc sulfate, which deposits a hydrophilic ("waterloving"), wetting
Know MoreCarbonatehosted leadzinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate (limestone, marl, dolomite) formations and which share a common genetic origin. Ore Ore genesis Galena Southeast Missouri Lead District Pine Point Mine.
Know More3 The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral. The flotation process collects the sulfurbearing portions of the ore, which also contains the valuable metal. First, the finely crushed ore is diluted with water and then poured into a tank called a flotation cell.
