Sulphide Gold Ore Treatment by Leaching and Flotation Process

A Flowsheet to recovery gold from sulfide ores. There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals ...

17 - Flotation of Gold Ores - Aalto

In flotation of gold-containing base metal ores, a number of modifiers normally used for selective flotation of copper lead, lead zinc and copper lead zinc have a negative effect on the floatability of gold. Such modifiers include ZnSO. 4 ·7H. 2. O, SO. 2,Na. 2. S. 2. O. 5. and cyanide

Flotation of Carbonaceous Matter from a Double Refractory Gold Ore: The ...

The use of alkaline pressure oxidation to pretreat refractory gold ore often results in insufficient gold recovery (<60%) in downstream thiosulfate leaching. To improve gold recovery, flotation was considered for the separation of carbonaceous matter (C-matter). In this study, the effect of MIBC on C-matter flotation was investigated to understand the role of the frother in bubble and froth ...

Fundamentals of Flotation - SlideShare

Froth flotation, is a physicochemical method of concentrating fine minerals and coal. It can be stated that Flotation is a physiochemical separation process that utilises the difference in surface properties of the valuable minerals and the gangue minerals. E.g. Removing silicate minerals from iron ores. 3.

Most often the copper minerals are floated after galena depression. Galena is depressed using sodium dichromate, sodium sulfite, polysaccharide (starch, dextrin) or even CMC. Addition rates of these depressants can be critical if any recirculating load is returned to the bulk rougher circuit. This flotation step is conducted at alkaline pH.
