cause of poor or bad effective froth flotation 4.6 3954 Ratings The Gulin product line, consisting of more than 30 machines, sets the standard for our industry.
Newly refined paraffin hydrocarbons, if pure, will not froth to a sufficient extent to make them efficient flotation agents in the agitation froth or pneumatic processes. Certain other substances, although possessing the property of froth formation in these processes, exclude practically all solid matter from the froth.
In the case of flotation, coarser particles will be lost along with the tailings due to the sanding effect. Another drawback of froth flotation is that it is not effective for oxidised coal. For Indian coal with a high percentage of near gravity materials it is advisable to go for the froth flotation method except when the coal is oxidised.
Microflotation was chosen as the technique used to relate flotation response to adsorption. The advantage of microflotation over other flotation systems, is its use of very small quantities of mineral and the ability to operate the system without the complicating froth phase.
Several authors, such as McKee, 1991, Laurila et al., 2002, agree that reasons for this include: a lack of appropriate instrumentation and technologies, and the old design of flotation plants; which consisted of numerous smaller cells making process control more complicated and cumbersome.
Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.
The entrainment of finely divided air in thickener feeds can cause significant problems in a thickener39;s operation, especially in mineral processing plants. This is particularly the case with...
Because the froth flotation process is strict with grinding fineness, pulp density, flotation reagent, the flotation plant operators must inspect the flotation conditions during the operation of the flotation machine. Here are some common problems of froth flotation process and their and solutions. 1.
