Gold mining process | Introduction | Integrated report ...

ACCESSING THE ORE BODY. Underground: Vertical shafts and decline ramps are sunk into the ground to transport people and equipment to and from deep-level ore bodies (many are more than 1,000m below surface) and to bring the ore mined to surface. Open pit: Near-surface orebodies accessed by “stripping” overlying material.

Reading: Mining | Geology

The process of mining from discovery of an ore body through extraction of minerals and finally to returning the land to its natural state consists of several distinct steps. The first is discovery of the ore body, which is carried out through prospecting or exploration to find and then define the extent, location and value of the ore body.

Silver Mining and Refining | Education

In this process, crushed ore is placed in a bath. Air bubbles are blown through the mixture to carry the silver to the top of the bath where it forms froth. The silver-rich froth is skimmed from the bath and smelted so that it can be separated from other metals. A diagram illustrating the froth flotation process.
