OSTIGOV Book Combining advanced flotation and centrifugal gravity separation for improved sulfur rejection
A comparative analysis of the combination of flotationmagnetic gravity separation with bulkfloatation process for recovering fine tin slime was carried out in a mineral processing plant compared to the bulk floatation process the flotationmagneticgravity separation process resulted in a higher recovery of tin and showed advantages of small consumption of reagents and electric power
