Galena, a lead sulfide (PbS), is heavy, brittle, and breaks into cubes. Sphalerite is a zinc sulfide (ZnS) mineral that is brownish, yellowish, or black. It ordinarily occurs with galena and is a major ore of zinc. The iron sulfide pyrite (FeS), which is also called fool's gold, is common in nearly all types of rocks.

The dressing of ore is also called concentration of the ore because it gradually increases the percentage of metal. In metallurgy, the concentration of ore is achieved in the following two methods. (i) Physicals Methods. Hand-picking is a traditional method of concentrating ore by merely picking it …

Lead and Zinc Ore: Chief lead ore is Galena (PbS) and Sphalerite is the major zinc ore. Total combined reserve of lead and zinc ores are estimated at about 179 million tonnes, out of which 2.3 million tonnes lead and 10 million tonnes of zinc may be classed as recoverable reserve.

Spiral Concentrator. Multotec has designed and optimised both single (SX4) and double stage (MX7 and SX7) Coal Spiral Concentrators to treat a size range of 2.0 to 0.1 mm. Gravity Fed Slurry Distributors Orifice and Slot Type. Gravity separation of fine heavy minerals in the size range 1.5 to 0.04 mm may be conducted on spiral concentrators.

For instance, some lead ore can be upgraded by gravity separation at a size of about 1 mm. After that, only the smaller bulk pre-concentrate is ground to 100 microns for Froth flotation. 4. Reducing transport costs. The more you upgrade your ore, the fewer transport requirements you will lose.

As main gangue minerals, calcite, dolomite, and some silicates are present in both ore types. Before 1960, the lead-vanadate-containing ore from different ore bodies was processed using gravity concentration. The processing plant for flotation of lead, zinc, and vanadate minerals was introduced by the end of 1961 and closed in 1978.

The gravity concentration techniques are often considered where flotation practice is less efficient and operational costs are high due to extremely complicated physical, chemical and mechanical considerations. ...
