Froth flotation Wikipedia

The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded (purified) by flotation technology. Prior to 1907, nearly all the copper mined in the US came from underground vein deposits, averaging 2.5 percent copper.

It is shown that the underground mine water has a deleterious effect on flotation performance. The adverse effect of the underground water was successfully negated by adding lime into the primary ball mills and increasing the pH of the slurry, from a ‘natural’ pH of 8

MEI Blog: Challenges in copper flotation. Sep 17, 2011 · Until 1907 practically all the copper mined in the USA was from underground vein deposits, averaging 2.5% Cu, whereas flotation allowed the mining of porphyry deposits of only 0.6% grade. Nevertheless, the flotation of copper ores still presents challenges to the minerals engineer.
