either primary or copper ores. Molybdenite is recovered from either primary molybdenite or copper sulfide ore by flotation, after the ore has been crushed and ground to a suitable size. Several stages of grinding and reflotation concentrate the molybdenite in the primary ore to a 90 to 95 percent purity concentrate.4 The remainder of the

The influence of grinding chemistry on the flotation behaviour of sulphides minerals has been widely studied. However, its influence on partially oxidised sulphide ores is not well documented.
Dec 20, 2018 The froth flotation method is widely used to treat various veins of gold and silver ores for the following reasons (1) In most cases, the froth flotation process can enrich gold and silver in sulfide concentrate to the greatest extent and discard a large number of tailings, thus reducing the smelting cost.
This couple is sufficiently reducing for the sulphide ion to function effectively as a depressant for pyrite. Chemisorption of sulphide ions on pyrite probably occurs similarly to sulphite4 ion on pyrite. Flotation of Chalcopyrite (CuFeS 2) Complete flotation of chalcopyrite is possible from pH 3 to pH 12 with ethyl xanthate.

Jan 01, 2021 As shown in Fig. 1, before flotation, 800 g lead-zinc sulfide ore, 500 g water, depressant (8000 g/t lime) and collectors (50 g/t sodium diethyldithiocarbamate and 50 g/t sodium butyl xanthate) were added to a ball mill and ground for 5.5 min.Thereafter, the pulp was transferred to an XFD-63 flotation cell (self-aeration) whose volume for flotation was 1.5 L
Lead-zinc sulphide ore contains lead sulphide (galena), and zinc sulphide (sphalerite). In the first flotation stage, galena is rendered hydrophobic with an organic collector such as xanthate, while sphalerite is kept from floating by depressants, and in the second flotation stage, activator was used to activated zinc flotation.
