Process Flowsheet Selection - ScienceDirect

The treatment of gold ores, in particular the competing technologies and their relative advantages and economics, is a major focus within the industry. A common issue is the increasingly refractory and complex nature of the ores being treated. This chapter, originally written in 2005, gives an overview of the key process options.

Beneficiation of Gold and Silver Ores | SpringerLink

Use of NaHS and silver ions has been reported to improve gold recovery at the Los Pelambres mine in Chile (Chryssoulis 2001 ). Sulfide ions appear to act as flotation activators at low concentrations less than 10 −5 M, whereas at concentration above 10 −5 M, it acts as a depressant (Aksoy and Yarar 1989 ).

Flotation of Gold and Gold-Bearing Ores - ScienceDirect

The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals ( Weinig and Carpenter, 1937, Rabone, 1939, Richards and L...

Use of large quantities of activated carbon in a full CIL circuit, i.e., a brute force approach to persuading soluble gold to adsorb onto the activated carbon added to the system. While relatively effective this method has disadvantages, in that the circuit requires high carbon inventories and a large elution and regeneration treatment capacity.

New Flotation Setup Provides Optimal Recovery for Macraes Gold

Here Peter Bourke, Outotec's global technology manager-flotation process and Alan Berzins, project manager-minerals processing, discuss the installation. Macraes gold was a two train plant. Each train consisted of an Outotec Flash flotation cell on the cyclone underflow which recovered 50%-65% of the sulphide minerals.

Gold recovery in the first half of the quarter was in excess of 90%, but subsequently has lowered to approximately 80%. This lower recovery is due to the treatment of previously stockpiled concentrate material, which is quite low in sulphide sulphur and gold grade. A third thickener was installed in the circuit towards the end of June.
