Copper Flotation - Mineral Processing Metallurgy

May 16, 2016  A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel ...

Gold Extraction Recovery Processes

Feb 29, 2016  Cyanide acts too slowly on coarse gold, but readily dissolves fine gold. Flotation concentration is not effective on coarse gold. The small miners who wish to treat a small tonnage of high grade ore and want a quick return rather than for recoveries near to 100%, probably still find the amalgamation process the best available recovery method.

An investigation on flotation process of low-grade

Froth flotation process has proved to be superior over other concentration methods when treating pyrochlore ((Na,Ca) 2 Nb 2 O 6 (OH,F) ores. This has led to use of reverse gangue flotation prior to pyrochlore flotation in cases were the ore contains high content of carbonate minerals [1]. Fatty acids are used as primary collectors.
