After using copper sulphate, pulp potential increased about 50 mV in dry and 75 mV in wet grinding methods. ... It is suggested that the effect of the grinding media, which is important for fine ...

Grinding media type is a critical factor in determining the chemistry of the flotation feed pulp and yet is infrequently studied in this regard by plant operators. The normal operating philosophy is to choose the grinding media which produces the correct grind at minimum economic cost, and adjust the chemistry by reagents and/or aeration.

A process for preparing ferrous sulfate includes such steps as reaction between waste dregs containing 3-valence Fe and sulfuric acid at 80-130 deg.C to obtain acidic solution of iron sulfate, adding troilite or sulfur ore concentrate to obtain ferrous sulfate solution, cooling to -10-20 deg.c for crystallizing, filtering, centrifugal drying and baking to obtain FeSO4.7H2O.

The results revealed that the type of grinding media and copper sulphate addition had an interactive effect on the froth stability. While mild steel (MS) milling increased the froth stability due ...

As seen in Fig. 8, when grinding was performed in the presence of tap water regardless of the type of grinding media, the sulphur high resolution spectra showed the presence of disulphide (2p 1/2 and 2p 3/2) and sulphate (2p 3/2 and 2p 1/2). When the synthetic process water was used, the sulphate level on the surface of samples significantly ...

Unfortunately, with the possible exception of the iron sulphate tests, none of these methods managed to improve galena/sphalerite selectivity when grinding with high chrome grinding media, and restore the lead grade/recovery curve to the same position as that observed for forged media (see Fig. 2).The iron sulphate tests indicated a more electrochemically active grinding media would …

Fig. 1 shows the recovery vs. time of the copper, nickel and iron sulphide minerals obtained for the condition of SS milling media with no copper sulphate addition and illustrates the different performance of the minerals. It can be seen that chalcopyrite (copper) was the fastest floating mineral and achieved the highest final recovery (85.6%). The final recovery of pentlandite (nickel) was …
