FLOTATION OF SULFIDE ORES - DOW CHEMICAL CO.:THE

The flotation collector compounds as defined herein are particularly suitable for use in standard flotation processes to concentrate copper sulfide and other like minerals from sulfide ores. In such processes, a pulp is first prepared by wet grinding the ore to a suitable size with or without a pH modifier.

Role of sodium sulfide in the flotation of oxidized copper ...

This paper reviews uses of sodium sulfide in the flotation of oxide minerals of copper, lead, and zinc. The activation and depression effects of sodium sulfide are of particular importance because of their applications with oxidized lead and copper ores. In spite of its industrial importance, the nature of the heterogeneous reactions between sulfide ions in solution and the surface of oxidized ...

Flotation of non-sulfide minerals is more difficult than that of sulfide minerals. The main reason is that non-sulphide ores usually have high water solubility, and the useful minerals and gangue minerals are usually of similar types, with a small difference in surface properties.

In the ZnS flotation, the maximum separation achievable for ZnS using froth flotation has been shown to be a grade of 72.57% and a recovery of 95.43%. At this time, FeAsS removal of 87.8% (0.16% As) could be successfully accomplished under pH 11, and 800g/t Zn activator (CuSO4), 75g/t frother (AF65), 60g/t collector (AP211) and 600g/t As ...

The Critical Role of Pulp Density on Flotation Separation of ...

In nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation . Large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing ...

Barry Wills' Blog: Flotation '19 Final Report

Dec 09, 2019 · In the flotation of sulfide ores, non-sulfide gangue is purported to report to the concentrate by entrainment. While it is long known that particle size affects entrainment, plant practice suggests that certain gangue minerals (e.g. mica) entrain more than others resulting in lower concentrate grades.
