A new collector used for flotation of oxide minerals

2009-10-1  Electronegativity of group is not invariable for it is influenced by the contiguous atoms[20]. Amine collectors are the common oxide minerals collectors, and the bonded atom in them is nitrogen. When the hydrogen is replaced by different radicals, the electro cloud density of nitrogen is changed. So, the collect capabilities of amines are changed.

A new collector used for flotation of oxide minerals

And in the whole flotation experiment, the flotation recovery of hematite rises with the increase of collector concentration and pH, while the maximal recovery is not more than 55%. Compared with dodecylamine, the N-dodecylethylenediamine has strong capability to quartz and calamine, while the flotation recoveries of calcite are closely. Hydrogen binding adsorption and electrostatic adsorption occur between the collector and the surface of quartz.

The use of alkyl hydroxamates as collectors for oxide

2018-1-2  It is generally recognised that hydroxamates are good collectors for the ‘well-defined’ oxide copper minerals, such as malachite (Lee et al., 1998). Most well-defined oxide minerals exhibit flotation maxima at pHs within ±0.5 of the pKa of the hydroxamate

A review of zinc oxide mineral beneficiation using

Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process. It appears that selective leaching is a promising method for the beneficiation of this type of ore.
