CHAIN EXTENDER AND EMULSIFIER APPLICATION IN IRON ORE FLOTATION

Blog Article

The present study aims to evaluate the reverse flotation performance of iron ore, using collector (amine), in the presence and absence of chain extender (diesel bostik mvp oil) and emulsifier (sodium lauryl sulfate).Six tests were realized with duplicate.Tests using amine, diesel oil and sodium lauryl sulphate show the better results, with metallurgical recovery of 91.82% and the concentrate silica equal 1.

68%.Thus, it is found apunisw2 that the use of emulsifier and chain extender together with the amine, shows better results in the flotation, in terms of metal recovery and selectivity, when compared to using only amine or amine and diesel oil.
