Rejection of antimony and bismuth in sulphide flotation – a literature
The key antimony minerals of commercial interest to remove are stibnite, tetrahedrite, and jamesonite, while the main bismuth mineral is bismuthinite. The most promising methods for separating antimony and bismuth minerals from sulphide ores are based on pH and/or pulp potential adjustments or the use of starvation levels of collector.
Flotation Technique for Fecal Parasite Concentration Methods
Procedures: 1. Crush 10-20g (about 1 teaspoon) of feces with applicator sticks and mix well with 10-12ml of saline. Filter the mixture through two layers of dampened surgical gauze into a 15ml conical centrifuge tube. 2. Centrifuge the suspension at 1500 rpm for five minutes.

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. Gold itself is a rare metal and the average grades for low-grade deposits vary between 3 and 6 ppm.

Floatation
The tendency of an object to rise up to the upper levels of the fluid or to float on the fluid surface is known as floatation. Sinking is just the opposite process of floatation which means the tendency of an object to go deep down to the lower levels of the fluid. The phenomenon of floatation totally depends on the density of the object placed ...
Flotation of Gold and Gold-Bearing Ores
