Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …

Mining, quarrying, and hydrocarbon (oil and gas) exploration are three different sectors. Mining is the process by which naturally-formed materials are extracted from the earth. These materials include gold, iron ore, coal, lead, silver, lithium (also from salt deserts), etc. Quarrying involves extracting materials from the surface of the earth.

Drift Mine Sampling. Underground mining procedures are collectively known as "drift mining" where applied to placer gravels. Placers buried under deep masses of low-value gravel or capped by lava flows have been extensively worked in this manner. Drift mining presupposes the concentration of values in a well defined stratum or channel.
