Copper Mining, the King of the Oquirrh Mountains

Another mill near the Magna Mill, constructed in 1909 by Boston Consolidated, later became part of Utah Copper and used the tailings pond. By 1918 the pond covered 5,000 acres. During 1906–7 an electric generating plant was built below the Magna Mill. Copper during World War II

Some factors that affect beneficiation of sulphide nickel–copper ores

The aim of the paper was the analysis of the influence of milling time on the laboratory flotation of the copper ore from stratiform Polish deposit. Three different milling time of copper ore in laboratory ball mill was applied. The flotation results were presented as the recovery-recovery and grade-recovery upgrading curves.

Optimization of Flotation of the Qaleh Zari Mine Oxidized Copper Ore …

The two main methods for flotation of copper oxide minerals are: i) direct flotation, and ii) flotation with employing sulfidation (Liu et al., 2020; Xingrog et al., 2021). The traditional method of copper oxide flotation involves sulfidation of the mineral surface prior to the addition of a copper sulfide collector (Bulatovic, 2016).
