Mining and General information on the tin

Mining

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.

Production

The production of tin goes through the following stages:

·ore-dressing;

·firing;

·sublimation;

·smelting black tin;;

·refining.

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.

The percentage of marks O1 and O2

Mark	Fe	S	Cu	As	Pb	Sb	Bi	Sn	Impurities
O1	≤0.009	≤0.01	0.03 — 0.01	≤0.01	≤0.04	≤0.015	≤0.015	min 99.9	≤0.1
O2	≤0.02	≤0.02	≤0.03	≤0.015	≤0.25	≤0.05	≤0.05	min 99.565	≤0.435

General information

Sn — another representative of the group of non-ferrous metals. Its main advantages — flexibility, corrosion resistance and good processability. Another indisputable advantage is the harmlessness of the metal. It is widely used in the food industry, and is a required component of virtually all anti-friction alloys.
