Effect of Copper Sulfate on Zinc Sphalerite Flotation

effect_of_copper_sulfate_on_zinc_sphalerite_flotation

As an example of the beneficial effect of copper sulfate in the activation of zinc sphalerite toward flotation, the series of results shown in Fig. 1 is of interest. These represent rougher tests on a sample of heavy pyritic ore. The particular sample in question contained about 5.6% zinc as marmatite; and was treated in a circuit […]

Flotation Uranium bearing Copper ore

Uraninite and masuyite are the major uranium minerals, essentially fine grained, in the ores studied. Over 40% of the uranium is distributed in the -8µm fractions compared with copper, which is concentrated mainly in the +8-20µm range. Uranium is concentrated mainly in the copper ore zones, with only marginal levels in the gold-only ores. Poor liberation […]

Froth Factor for Pump Sizing

The ‘froth factor’ is a measure of the air contained in the froth. It is quantified by filling a measuring cylinder or bucket, of known volume, with froth and measuring the froth column. After air dissipation the remaining water and solids volume is measured. The ratio of the original volume of froth to the remaining […]

MIBC Frother Pump

Flotation Frother Pump

I once had to conduct an MIBC frother test to confirm if it could give me better flotation results than the glycol frother my client was using. The technical/metallurgical problem we had in the plant was best described in the video below as well as a poor concentrate grade. My “challenge” was that since MIBC […]

Gold Flotation

Hydraulic Gold Trap

Though the gold recovery methods previously discussed usually catch the coarser particles of sulphides in the ore and thus indirectly recover some of the gold associated with these and other heavy minerals, they are not primarily designed for sulphide recovery. Where a high sulphide recovery is demanded, flotation methods are now in general use, but […]

Gold Flotation Tests

Zinc Sphalerite Flotation

The first gold flotation testing should be confined to an all-flotation method so that the experimenter can become familiar with the ore. Careful observation, coupled with experience in testing, will enable the operator to interpret the various phenomena. It is desirable that he shall have had practical operating experience so that he may know the […]
