Influence of attrition variables on iron ore flotation - CORE

Attrition is present in the flowcharts of the beneficiation process of phosphate and industrial sand (silica sand). Research has been undertaken for its application to produce pre-concentrates of zircon and iron ore. However, there is still little knowledge of the influence of the attrition variables on the beneficiation process of iron ore.

2019-3-20  The presence of sludge in iron ore reverse flotation is known to be harmful in many ways. Traditionally, desliming fulfills the role of removing some of this sludge. However, depending on the porosity and how it is presented on minerals and gangue, desliming may not be sufficient to maximize the concentration results. The sludge can be removed more efficiently by adopting the scrubbing then ...
