PROCESS FOR THE RECOVERY OF TIN FROM TIN ORES

Processing tin ores and other tin-bearing flue dust by means of the volatilization of the tin in the form of tin sulfide is in itself a process which has been known for a long time, for which as the years went by, a number of proposals has been made. In this process, use is made of the volatility of SnS at higher temperatures (boiling point

Tin processing Mining and concentrating Britannica

Tin processing Tin processing Mining and concentrating: Vein deposits, such as those in Bolivia and the United Kingdom, usually occur in granite formations and are recovered by conventional underground hard-rock mining techniques. In deep mines, primary crushing equipment is usually located underground in order to reduce the ore to a manageable size

Extraction of tin from its ores Manchem Limited

A process for the direct recovery of tin, as an organo hydrocarbyl tin compound, from reduced but unrefined tin ores and ore slags is described, wherein the ore is reacted directly with a hydrocarbyl halide to form an organo hydrocarbyl tin compound which can then easily be removed and separated from the tin-depleted ore residue.

Tin Ores Article about Tin Ores by The Free Dictionary

Tin ores from native deposits are processed by gravitation in ore-dressing plants. Combined gravitation and flotation methods are used when difficulties are encountered in dressing certain ore varieties. The resultant pure, admixture-free tin concentrates, which contain about 60 percent Sn, are ready for smelting.
