Mining and General information on the tin


In recent years, the mining of tin ore in the world has a tendency to increase the volume, and connect it with the development of electronics and the increasing demand for solders containing no lead. According to world statistics today, the production of tin is concentrated in China, Indonesia, Brazil, Bolivia and Peru. They are the undisputed leaders in the production of this metal.


The production of tin goes through the following stages:




·smelting black tin;;


There are 2 most common types of refining — electrolytic, and thermal. Refined tin grades of O1 and O2 is produced in accordance with the standards GOST 860−75.
