Atrac In Flotation Of Iron Ore

Studies on the influence of a flotation collector reagent

2008-3-10  The properties of iron ore green pellets with varying additions of a surface-active flotation collector reagent (Atrac) were studied by small-scale balling. The compression strength and plasticity were measured with a semi-automatic measuring device and the pressure curves were saved and subjected to further mathematical treatment.

Flotation applied to iron ores with complex mineralogy

A low-grade iron ore from one of the largest Mexican deposits was investigated.
