Polyacrylamide Used in Flotation Sinofloc Chemical
Polyacrylamide Used in Flotation. Flotation means fine mineral particles can be aggregated into larger particles to accelerate their settling speed in water, and selective flocculation can be used for Flocculation-desliming and flocculation-flotation in mining. Common used flocculants are polyacrylamide and starch.

Molybdenite Flotation in the Presence of a Polyacrylamide
2020-10-9 Polyacrylamides (PAM) are used as flocculants in the copper-molybdenum mining industry to improve the settling rate of flotation tailings. These types of reagents are recirculated to flotation in the water that is recovered from the thickeners, and as a result of this practice they can cause depression of flotation of some important minerals such as molybdenite.

The depressing effect of an anionic polyacrylamide on
2021-11-20 The effect of a carboxylated polyacrylamide (PAM) of 11.9% of degree of anionicity on molybdenite flotation was previously reported. In this work the depressing effect of a polyacrylamide of 8.15% of degree of anionicity (LPAM) on molybdenite flotation under different conditions of mechanical degradation, pH, and concentration is presented.

Selective depression of pyrite with polyacrylamide
2001-1-1 In the flotation of complex sulfide ores, a high pH value is generally used to separate valuable sulfide minerals from pyrite or pyrrhotite with xanthate collectors (e.g., Shen et al., 1998, Ball and Rickard, 1976). Fig. 1 shows that pH values larger than 11 are necessary to markedly depress pyrite flotation in the presence of xanthate collectors. The flotation of copper-activated

The effects of polyacrylamide flocculants on sulphide
Residual polyacrylamide was detected in the supernatant water even at low flocculant addition rates and reached significant concentrations before the optimum addition rate was attained. The effect of polyacrylamide on flotation of a copper-molybdenum ore was investigated in a series of batch flotation tests.
