Tin Ore Assay.—The ore to be smelted or assayed should be concentrated to say not less than 50 per cent, of metallic tin; though to obtain satisfactory results it should be brought nearer 70 per cent., as with ore containing less than 40 to 50 per cent, of metal there will be a considerable loss both in the assaying and in the smelting.

Tin - Wikipedia

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery metal that characteristically has a faint yellow hue. Tin, like indium, is soft enough to be cut without much force. When a bar of tin is bent, the so-called “tin cry” can be heard as a result of sliding tin crystals reforming; this trait is shared by indium, cadmium, and frozen mercury.
