Gold Mining Floatation
A Comprehensive Guide to the Gold Leaching Process
Gold leaching is a fundamental process in the extraction of gold from ores. It involves dissolving gold from its ore using a chemical solution, commonly known as a leach reagent. The gold leaching process has been extensively studied and refined over the years to improve efficiency and minimize environmental impact.

In this work, different flotation–preoxidation–cyanidation methods are considered for treating a low-grade refractory gold ore. On the one hand, the results of selective flotation show that 22% and 31.1% of total Sb and As, respectively, remained in the final tailings and only about 28% of the total Au remained for further cyanidation processes.

The Balm Creek Mine is intrinsically tied to the Poorman Mine as they both were developed by the same company in the late 1930s. The mines were shut down in 1937 when the price of copper dropped more than 50% within a few months. Prior to this, the mine operated for 5 years consistently employing 50 men and a 100 ton floatation mill.
