The principal difficulty in the Pyrometallurgical technique for gaining tin metal is the separation of tin from iron due to the high temperature of smelting. The smelting conditions should be such that the tin oxide is reduced to the metallic state while iron oxide is reduced to lower oxide (the ferrous oxide) and passes into the slag. Besides that the reduction of some iron

Pyrometallurgy is a branch of extractive metallurgy. It consists of the thermal treatment of minerals and metallurgical ores and concentrates to bring about physical and chemical transformations in the materials to enable recovery of valuable metals. Pyrometallurgical treatment may produce products able to be sold such as pure metals, or intermediate compounds or alloys, suitable as feed for further processing. Examples of elements extracted by pyrometallurgical processes include the oxides of less reactive ele

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. Therefore, magnetic separation and flotation methods will be used in tin ore dressing.

08/09/2020  In general, chemical reduction is much less expensive than electrolysis, and for this reason, chemical reduction is the method of choice for the isolation of these elements. For example, it is possible to produce potassium, rubidium, and cesium by chemical reduction, as it is possible to reduce the molten chlorides of these metals with sodium metal. This may be surprising given that these ...
