The Guide of Flotation Defoamers - Eco-friendly Gold Leaching
Flotation defoamer is a kind of defoaming agent which is mainly refined by mineral oil silicon and other special processes to solve the problem of defoaming in beneficiation. Flotation defoamer can be divided into oil type solution type emulsion type powder type and compound type from the properties.

2 17. Flotation of Gold Ores. also for beneficiation and separation of difficult-to-treat refractory gold ores. Flotation is also the best method for recovery of gold from base metal ores and gold-containing PGM ores. Excluding gravity preconcentration flotation remains the most cost-effective bene ficiation method.

Sequential Copper-Nickel Flotation. In sequential flotation pH is raised to pH 11 with lime and a starvation dosage 6 g/t – 15 g/t of AEROPHINE Ⓡ 3418A promoter is used. This allows selective flotation of a high grade copper concentrate with minimal nickel content. Slurry pH is then reduced to about pH 9 and a nickel concentrate is produced.

5 Types Of Gold Flotation Reagent
Gold flotation reagents can be divided into 5 types: collectors foaming agents inhibitors activators and pH regulators. Flotation reagent is one of the key factors affecting the flotation of gold ore. It can adjust the surface properties of gold ore during the flotation process and improve the flotation speed and selectivity.
Flotation taking its coarse
Coarse flotation is becoming more important as ore grades decline; when ore grades are lower there is less ore suitable for beneficiation. As a result new mines need to process additional tonnage to extract the same amount of metal or minerals as they would extract from higher-grade deposits.
