Placer mining

Placer mining / ˈ p l s ər / is the mining of stream bed deposits for minerals.This may be done by open-pit (also called open-cast mining) or by various surface excavating equipment or tunnelling equipment.Placer mining is frequently used for precious metal deposits (particularly gold) and gemstones, both of which are often found in alluvial deposits—deposits of sand and gravel in Get price

Criticality of metals and metalloids

In the past decade, sporadic shortages of metals and metalloids crucial to modern technology have inspired attempts to determine the relative "criticality" of various materials as a guide to materials scientists and product designers. The variety of methodologies that have been used for this purpose have (predictably) resulted in widely varying results, which are therefore of little use Get price

Gold: History of Use, Mining, Prospecting, Assay

Deposits of this type are mined for the predominant metals, but the gold is also recovered as a byproduct during processing of the ore. Most byproduct gold has come from porphyry deposits, which are so large that even though they contain only a small amount of gold per ton of ore, so much rock is mined that a substantial amount of gold is recovered.
