Silver Gold Recovery Flotation Process

Both gold and silver may be present, the gold values being usually associated with chalcopyrite and pyrite, and the silver with galena and tetrahedrite. Flotation follows ordinary standard methods, modified as may be necessary to bring up the precious metals in the concentrates where they will be of most value. Thus, in a lead-zinc ore, silver is more valuable in the lead than in the zinc

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

Optimisation of gold recovery by selective gold flotation

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 free gold can be selectively floated away from an ore containing sulphides. This may be an alternative treatment route for gold room applications where

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. It has been described as "the single most important operation used for the
