The flotation of marcasite and pyrite observed at pH 10 and at higher concentration of xanthate in the solution (10-4-10-3 mol 1-' ) can be regarded as an example. As was found in this work, under these conditions only the monolayer form of iron xanthate in the amount required for monolayer coverage is present on the marcasite surface.

One of the biggest motivations behind using froth flotation as the preferred slag cleaning method is the comparatively high levels of Cu recovery it provides (Schleisinger et al., 2011).Indeed, historical accounts of a Finnish smelting operation already showed that Cu recovery with an electric furnace was of 77% but with the introduction of flotation as the slag cleaning …

Pyrite particles, having framboidal/altered texture, are known to significantly affect pulp chemistry and adversely affect flotation performance. Therefore, the main objectives of this study were to demonstrate influence of pyrite mineralogy on the flotation of copper (sulphidic) ores and develop alternative conditions to improve the performance. Two copper ore samples (Ore …

The interaction of O 2 with pyrite, marcasite and pyrrhotite surfaces was studied using first-principle calculations to obtain the oxidization mechanisms of these minerals. The results show that the adsorption energy of O 2 on pyrrhotite surface is the largest, followed by that on marcasite surface and then pyrite surface. O 2 molecules adsorbed on pyrite, marcasite …

To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit.
