Flotation of Gold and Gold-Bearing Ores ScienceDirect

2016-1-1 · Flotation of Copper–Gold Ores. For the bulk flotation of copper minerals and gold from supergene copper ores, it is normal practice to add a xanthate as the primary collector and dithiophosphate as a secondary collector (Bulatovic, 1997). This combination gives satisfactory results in respect of copper concentrate grade and copper and gold recoveries.

2016-7-13 · Copper sulphate is frequently helpful in accelerating the flotation of pyrite and arsenopyrite. In rare instances sulphuric acid may be necessary, but the use of it is limited to ores containing no lime. “Ammo-phos,” a crude monoammonium phosphate, is sometimes used in the flotation of oxidized gold ores.

Optimisation of gold recovery by selective gold

This may be an alternative treatment route for gold room applications where fine gold losses can occur when treating gravity concentrates with pyrite and copper sulphides present. Floating gold from the sulphides could produce a directly smeltable product. Copper sulphides are selectively floated from pyrite ores at high pH's in excess of 11.

Separation efficiency improvement of a low grade copper

2017-12-21 · configuration is sequential flotation, where copper bearing minerals are recovered to a saleable copper concentrate, followed by re-activation and flotation of the pyrite which is leached with cyanide to recover gold. Both trains produce a copper concentrate with significant quantities of non-sulphide gangue minerals.

Notes on flotation of gold and copper ores, mount

HAVING held for some months, in 1913, the position of metallurgist in charge of the flotation department at Mount Morgan, it occurred to the writer that a description of the research work that he carried out on that ore would be of interest to members of the Institute. The Mount Morgan ore is virtually a mixture of iron pyrites, copper pyrites, and gold in a quartzose gangue.
