gangue minerals liberated

Liberated 0–10 μm particles from sulphide ores, their ...

2006-5-1  Gangue mineralsA number of mechanisms can contribute the recovery rates of liberated gangue minerals in the 0–10 μm fractions. The most important of these is often the recovery by entrainment in the recovered water (often acting on a relatively high percentage of the gangue in the feed in this size fraction).

2020-11-1  Reduction in size also increased, but not as dramatically, the percentage of gangue minerals liberated in the case of ItX and Canga, both containing a significant proportion of locked gangue even at fine sizes. Very limited liberation of gangue minerals is observed in the case of Canga, even for the finest size class (75–38 µm).

Evaluation of the response of valuable and gangue minerals ...

2015-4-1  The aim of this paper is to assess the recovery of valuable minerals for a low-grade complex silver ore in a size-by-size and size by liberation analysis. The minerals that were the focus of the study concentrated on pyrite and sphalerite as the main sulphide minerals in the ore. All remaining minerals were grouped as non-sulphide gangue (NSG). 2.
