INFLUENCE OF FLOTATION PARAMETERS ON DECREASING

of concentrates. The Gol-e-Gohar iron ore concentrate suffers from high content of S (0.5%) and to some extent P (0.08%), which are higher than permitted limit of 0.1% S and 0.05% P (Svoboda, 2004). Therefore, it is very important to remove and/or decrease the sulfur and phosphorus contents from the Gol-e-Gohar concentrate. In this

Flotation of Iron Ore: A Brief Review - MDPI

two technical routes of iron ore flotation have been developed: (i) direct flotation of iron oxides and (ii) reverse flotation of gangue minerals by depressing iron oxides. The route of reverse flotation is currently in widespread use in iron ore flotation practice. The majority of studies on reverse flotation of iron ore

Role of silica and alumina content in the

10-03-2016  Flotation studies of naturally occurring iron ores further established the fact that it is easier to upgrade the iron values from a high silica ore compared to a high alumina ore. It was possible to produce an overall iron concentrate containing 62% Fe with 86% recovery for a silica bearing ore, but the grade and recovery of an alumina bearing ore were found to be low.
