The flowsheet below Explains the Extraction of Tin Ore as shown by a study adapted to the concentration of a lode tin deposit.Cassiterite (SnO2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines. The Mineral Jig is an important feature of this flowsheet to recover the coarse free tin mineral as soon as liberated.

For this endeavour, the slags generated during the tin beneficiation process in the Penouta mine (located in Spain) will be analysed as a future source for both metals. Different geological studies were carried out, but the mine ceased its activity in the 1980s due to a decrease in tin price and depletion of higher ore grade zones.

The flow sheet of alluvial tin ore is usually very easy with simple screening and gravity separation involved to get high grade tin concentrate. For alluvial tin of low single separation degree, ore milling and further gravity separation will be needed after screening and gravity separation to guarantee the concentrate grade and recovery of the whole tin beneficiation processing line.

Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue.Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

Antimony ore can be divided into antimonite, cubismite, antimony ochre, etc. Due to the difference in the nature of the ore, the process used is also different. Commonly used beneficiation processes include manual separation, gravity separation and flotation . This article briefly introduces these three commonly used antimony ore beneficiation processes.
