Processing gold concentrate flotation system

Jul 13, 2016 Where a high sulphide recovery is demanded, flotation methods are now in general use, but in the days before flotation was known, a large part of the world’s gold was recovered by concentrating the gold-bearing sulphides on tables and smelting or regrinding and amalgamating the product. Though the modern trend is away from the use of tables, because flotation is so much more

    Advancing flotation process technologies to maximise gold

    Sep 13, 2017 A flotation process is one method used throughout the industry to recover gold. It’s a very cost-effective method for concentrating gold, and is a desirable process used for the upgrading of low-sulphide and refractory ore for further gold recovery treatment. Froth flotation is a process used to selectively separate hydrophobic materials from hydrophilic materials
