The present study aims to evaluate natio glide on eyeshadow stick the reverse flotation performance of iron ore, using collector (amine), in the presence and absence of chain extender (diesel 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 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 click here amine and diesel oil.
