Flotation Of Morobe Mining Oxide Ore Collector

Flotation of mixed copper oxide and sulphide minerals

2009-3-1  The application of alkyl hydroxamate as a metal oxide mineral collector has been studied since the early 1940s. Popperle (1940) first patented the use of hydroxamic acids or their salts as collectors for ore flotation. Much research followed with the development of a number of different hydroxamate collectors.

2019-7-1  While flotation is a common method to concentrate sulphide ore in the DRC, oxide ore requires sulphidisation prior to flotation with xanthate collectors (Crundwell et al., 2011). The flotation of sulphides and sulphidised oxides must be done separately as reagents used for sulphidisation of the oxide minerals will cause depression of sulphide ...

Physicochemical studies of oxide zinc mineral flotation

2016-9-29  The studies on oxide zinc ore indicate a maximum bench scale flotation recovery of 84.5 % with zinc grade 24.5% in the presence of dodecylamine at pH 11.5. There are no significant variations in recovery of cationic and anionic and mixed collectors, however, amine and mixed collector flotation show to be more selective than anionic collectors.
