2020-9-9  1.Conventional flotation method . When using conventional flotation methods for beneficiation, oleic acid and its soaps are commonly used. The application technology of this collector is very mature and it is more reliable in application. However, it also has a major disadvantage, that is, the amount of material used is too large.

Pneumatic Flotation Challenges Conventional

2020-4-8  For example, using a Pneuflot unit has upgraded a 0.2-g/mt gold tailings feed to 5 g/mt gold at 2% yield and 18% metallurgical recovery. Similarly, the technology has been used to treat ultra-fine platinum ore grading 5.1 g/mt (0.15 oz/ton) that could not be processed using conventional technology to give 20 oz/ton in the final concentrate.

Two applications showed immediate promise. The first used the HydroFloat to scavenge the final tails of a conventional concentrator plant. We called this the tail scavenging application. The second used the HydroFloat as an ore sorter, by operating inside the mill circuit to reduce the grinding intensity and generate a coarse barren tail.

Barrick Gold Corporation New Technology Uses Salt

2016-9-29  In the conventional flotation process, which has been used for decades, finely ground ore is mixed with fresh water and chemical reagents to form a slurry. The slurry is pumped into a large tank and valuable mineral particles are floated to the surface via air bubbles, while waste particles sink to the bottom of the tank.

Mineral Extraction, Mineral Processing Mining-pedia

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
