The flotation reagent consumptions are minimum. The majority of chalcopyrite remains in the sulfur flotation tailings and can be readily recovered by flotation with different flotation reagents. When amyl xanthate is used, 85% of chalcopyrite can be recovered with a copper grade of 14.5% in a single-stage froth flotation. The chalcopyrite

US6889844B1 - Collectorless flotation - Google Patents

The present invention relates to a process for improving the recovery of valuable sulphide minerals. The process involves determining an Eh range within which the valuable sulphide mineral may be recovered by flotation without the need of a collector. The slurry is then subjected to flotation in a pneumatic cell ( 50 ) at such a speed that the slurry remains within the Eh range during flotation.

How to Calculate Buoy Floatation in the Water | Sciencing

Apr 24, 2017· Note that the buoy, if held under water, displaces 124.8 pounds of water. According to Archimedes' principle, the buoyant force acting on the cork is 124.8 pounds, which is greater than the weight of the cork. Therefore, if the cork is released the buoyant force pushes it to the surface, where it remains partially immersed.

Deinking - Wikipedia

Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp. The key in the deinking process is the ability to detach ink from the fibers. This is achieved by a combination of mechanical action and chemical means. In Europe the most common process is froth flotation deinking.
