17 - Flotation of Gold Ores
The flotation method is a technique widely used for the recovery of gold from gold- containing copper ores, base metal ores, copper nickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used forFlotation of Gold and Gold-Bearing Ores - ScienceDirect Many copper flotation plants around the world, and particularly those in the Americas, have enough gold in the ore to ensure that special attention is given to maximize the recovery of gold into the copper concentrate.Separation efficiency improvement of a low grade copper-gold . The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed remaining gold is recovered both as a gravity product within the primary grinding circuit and also via leaching of a gold-containing pyrite concentrate .
PDF A Review of the Flotation of Copper Minerals
The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu open pit mines and 1-2%TCu underground mines is of great commercial importance..Size dependent gold deportment in the products of copper . Flotation is the principal method of pre-concentration for copper and gold5,6. Thus, porphyry copper ore concentrators are designed with the goal of maximizing copper recovery and grade; however, gold recovery as a by-product is also economically important7.Froth Flotation and Gold Extraction - Manhattan Gold and Silver Froth flotation is a method for separating hydrophobic materials which will not mix with water from hydrophilic materials which readily mix with water . Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold.
