The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity - known as doré - typically containing between 60-90% gold. During its life, a number of factors - such as the ...

Early copper mining began at the site in 1900, with open pit stripping beginning in 1959. In 2012, the mine produced 134 million pounds of copper concentrate, paid $6.6 million in state royalties and $2.5 million in tribal royalties, and employed 620 people. The mine is expected to produce until 2033.

Gravel and Aggregate Mining often requires the removal of materials that provide protective coverage over ground-water aquifers. It is important to avoid practices that may contribute contaminants to the aquifer. Improperly managed mining operations can inadvertently contaminate drinking water supplies and require years for ecosystems to recover.

In the literature, several frequent itemset mining algorithms using a vertical data layout were proposed such as Eclat [ 21 ], Diffset [ 20 ], VIPER [ 15] and MAFIA [ 3 ], and also an implementation of Eclat over the MapReduce platform [ 22 ]. In the latter, the authors propose to execute the Eclat algorithm on each MapReduce node.
