After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal. William Andrew Hustrulid
Tin mining dates back to the Bronze Age when it was used in a coppertin alloy to form the metal known as bronze. Since then, the industry has come a long way to develop the current tin mining process and production levels of today.

It is purified further using electrolysis. This is known as electrolytic refining. The blister copper is cast into large slabs which will be used as the anodes in the electrolysis apparatus (see page 4). The electrolytic refining of copper produces the high quality, high purity copper required by industry.
The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
