Tin Slag

Tin Slag

Tin slag is a by-product generated during the smelting and refining of tin ore. It consists of various impurities, residual metals, and oxides that are separated from the molten tin during the extraction process. Tin slag typically contains a mixture of compounds such as silica, iron oxides, alumina, and residual tin, as well as other elements like copper, lead, and zinc, depending on the specific ore being processed.

During the smelting process, the ore is heated to high temperatures, causing the tin to melt and separate from the impurities, which form the slag. The slag, being less dense than the molten tin, floats to the surface and is then removed. This material, while often considered waste, can sometimes be further processed to recover any remaining tin or other valuable metals, making it a resource of secondary value.
