9 Step Process for Discovering, Mining Refining Gold

Step #6 – Mining samples and determining processing. Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore. This is done in order to determine the appropriate processing technique. Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done.

physical and chemical methods used to refine the mineral

In general there are two methods of vegetable/edible oil processing, one is physical refining and the other is chemical refining. However, no matter what kinds of reining methods, they are all done with the help of various oil processing equipment and machinery, and are used to refine almost all kinds of oil extracted from oil.
