Ilmenite disseminated grain size is relatively fine, and it must be finely ground to fully separate ilmenite from gangue then produce fine-grained minerals, which deteriorates flotation. A novel method using buoyant carriers improve the recovery of fine in froth flotation was introduced this study. Hydrophobized glass bubbles (HGB) as carrier materials were obtained by an efficient, simple modi...

Scientists and technologists in world over are making large efforts to streamline the conventional technological schemes of ore processing, in particular froth flotation towards reducing overall costs, limiting the use of dangerous substances, decreasing waste streams and improving waste disposal. Hitherto, search for such innovations has been performed mainly empirically and there is an urgent...

Pyrrhotite-bearing aggregates are a major cause of internal sulphate attack (ISA) in concrete. The concentration pyrrhotite is usually too low to permit direct accurate quantification. Hence, safety restrictions put on expressed terms the total sulphur content. This paper outlines an analytical approach which froth flotation employed produce bulk sulphide concentrate amenable quantification pyr...
