Gold Smelting & Refining Process
The charge is heated slowly until boiling point of mercury is reached. At this point the mercury is eliminated and condensed in cooling tubes passed through water. Obviously, some losses can be produced and this can be estimated as 0.065 grams per 255 grams of mercury. The process takes two to three hours.
9 Step Process for Discovering, Mining & Refining Gold
Step #1 – Finding Deposits. The first step is discovering where gold deposits may be. Geologists use special 'geology' maps to look for promising areas to explore further. They examine physical and chemical characteristics of surface rocks to determine if any gold is in the ground beneath. Step #2 – Analysis of Promising Areas.

Gold Mining Process
Next, blasting occurs to break down the rock making it easier to move. A fleet of excavators mine designated ore areas and move the gold containing ore to stockpiles. The stockpiles containing the ore will be processed to extract the gold. Trucks move waste to a waste rock stack, which can be rehabilitated to fill previously mined areas.
