Froth Flotation Principles

The Froth Flotation Machine and its operating principles are universally used for all types of flotation problems.This machine finds a wide acceptance due to its flexibility in construction, which allows the machine to be adjusted to handle pulps with divergent physical characteristics, as well as the common and intricate metallurgical problems which confront the present day operator.

EFFECT OF PARTICLE CHARACTERISTICS ON FATTY ACID

The industry now frequently encounters difficult-to-float phosphates, with flotation recoveries 20% lower than normal. The extent of this problem and the reasons for the poor flotation performance are not understood. There has been some speculation on the cause of this problem, such as organic coating on the phosphate surfaces, higher pyrite

can gypsum float on water??? , Yahoo Answers

Dec 21, 2006· Best Answer: This is a tricky question. Generally the specific gravity of gypsum is greater than water and therefore it won't float. However, if the gypsum is a little amount of very fine powder, it is possible to sit on the water as its mass will not be great enough to break the surface tension.

The presence of gypsum scale formations on the technological equipment surfaces is a common problem in industrial technological processes. The

Production of epsom, gypsum and other industrial products

Reaction time of 3 h is required to get 95–98% conversion. Filtration of the material produced 16–18% solution of MgSO4. The gypsum needs to be washed thoroughly with hot water (60–70°C) to remove all the absorbed solution of MgSO4 from gypsum. Crystallization of epsom was carried out in two stages at 25–30°C and subsequently at 10°C.
