The flotation of gold bearing ores — A review - ScienceDirect

Jul 01, 1994  The flotation of gold bearing ores--a review 84.5 Residence Time Because flotation is often a rate controlled process it is important to optimize the cell residence time. It has been reported that the rate of gold and pyrite flotation is greater from plants treating coarse milled ores than from those treating finer ores or tailings.

Froth Flotation Method - JXSC Machine

Dec 20, 2018  The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons: (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.

Jul 01, 2014  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.
