Describes a Malaysian school project which deals with tin, and extracting tin from its ore in the laboratory, as well as the economics involved and the locating and mining the ore. HM
Extraction of tin from its ore generally adopts gravity separation method, which is determined by the density of tin ore than the characteristics of paragenetic minerals. However, iron oxides such as magnetite and hematite are often associated with tin ores, so gravity separation is not possible.
Tin Ore Mining Production Line 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
