Flotation of Gold and Gold-Bearing Ores - ScienceDirect
7.5. 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 ...

Froth flotation - Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, stone recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Optimisation of gold recovery by selective gold flotation ...
Optimisation of gold recovery by selective gold flotation for copper-gold-pyrite ores. ... Abstract. Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the ...
Effects of particle size on flotation performance in the ...
Considering the flotation performances of copper and gold, the optimum size fraction in the flotation separation of Cu Au minerals from Pb components was −74 + 20 μm. (2) The classical first-order model (Model 1) was considered to be most reasonable for fitting the recoveries of copper, gold and lead as a function of flotation time during ...
The Effect of Sulfurization Process on Flotation of Copper ...
flotation behavior of gold in synthetic mixtures and not when it is a component of a real ore containing other gold bearing sulphide minerals and siliceous gangue. There are also some research documented on the flotation of gold bearing pyrites [3] and arsenopyrite [4]. However, these studies have not included free gold particles.
Flotation of gold and gold-bearing ores - PDF Free Download
Copper–gold ores are significant contributors to the overall world gold production. Flotation is the principal process for pre-concentration of the copper–gold minerals for subsequent smelting treatment. Gold recovery, although important, is not always considered when optimizing the copper circuit.
Froth Flotation and Gold Extraction - MGS Precious Metals Blog
Jul 23, 2014 · Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity. First, refractory gold ore is ground as finely as possible – usually so the individual ...

gold in copper rougher flotation tailings (0.07% Cu , 0.61g/t Au, tail grades). An aeration stage was applied both at the head of copper flotation (copper rougher feed) and after regrinding of the copper rougher tailings, before gold/pyrite selective flotation. Also, different collector
Froth Flotation Method - JXSC Machine
The vast majority of polymetallic sulphide ores containing gold and silver are treated by this method. When flotation of such ores, gold and silver enter into the copper concentrate or lead concentrate closely associated with them. The products are called copper, gold and silver concentrate or lead, gold and silver concentrate, etc.
