On the Management of Gangue Minerals in the

2018-12-5  The major challenge in the flotation of these ore bodies is the control and management of the gangue minerals, particularly silicates such as orthopyroxene, plagioclase feldspar, and pyroxene which are often rimmed with talc which makes them naturally floatable.

Transport of fibrous gangue mineral networks to froth

2012-3-20  Flotation beneficiation of ores containing fibrous minerals is highly problematic due to transport of such gangue minerals from pulp to the froth phase. Earlier studies have attributed such transport to the entrainment of fibrous minerals.

Minerals Free Full-Text The Role of Gangue

The mineralogical compositions of current fluorite deposits are becoming increasingly complex, making the selective flotation of fluorite from gangue even more challenging. Typical gangue minerals include calcite, quartz and barite [ 1 ]. Some sulphide gangue minerals, such as pyrite, galena and sphalerite, may also be present in fluorite ores.

Mechanism for the recovery of silicate gangue

2007-7-1  Flotation is a complex process in which valuable minerals are separated from gangue minerals (Leja, 1982). The separation is based on the surface properties of each mineral phase present in the suspension (Mitchell et al., 2005, Çilek and Yilmazer, 2003, Luz et al., 2002).

Interaction of gangue minerals with malachite and ...

2018-10-20  The current work confirmed that understanding the sulfidization flotation of malachite involves consideration of interactions of gangue minerals including calcite and quartz slimes with malachite. The flotation results show that calcite depressed malachite in sulfidization flotation at approximately pH 9.5 while quartz seems to have little or no effect on malachite.

The effect of non-sulphide gangue minerals on the ...

2014-6-1  In this study, the focus was on the role of non-sulphide gangue (NSG) minerals. It was hypothesised that specific NSG minerals have a detrimental effect on flotation recovery of gold bearing minerals and their separation selectivity. In order to test this hypothesis and delineate the effect of the various gangue minerals, a new approach was taken.

Removal of Gangue Minerals Containing Major

The removal of gangue minerals containing major elements was investigated using a reverse flotation method. Experiments were conducted on lignite samples, with high-ash and low-sulphur contents taken from a lignite field in Karlıova-Derinçay (Bingöl), Turkey. Predominant gangue minerals in the samples were found to be quartz, gypsum, feldspar minerals, mica minerals, and clays (smectite group).
