Talc, or talcum, is a clay mineral, composed of hydrated magnesium silicate with the chemical formula Mg 3 Si 4 O 10 (OH) 2.Talc in powdered form, often combined with corn starch, is used as baby powder.This mineral is used as a thickening agent and lubricant; is an ingredient in ceramics, paint, and roofing material; and is a main ingredient in many cosmetics.
[Introduction]: The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore is gravity separation.However, all kinds of iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation.
