ABSTRACT OF THE DISCLOSURE The negative effects of sodium oxalate on the crystallization of aluminum trihydrate from Bayer process liquors may be eliminated or curtailed by adding an effective amount of a polyacrylic acid, with a molecular weight about 1,000,000 and containing at least 50 mole percent acrylic acid monomer, to pregnant Bayer process liquors.
The dissolution of aluminum from bauxite residues may become a more important topic in the future, as stricter and stricter regulations aiming at improved material efficiency and waste minimization take effect. As for sodium above, the results presented below in Fig. 8a and b do

The beneficial effect of backfill proposed in the new up-dip mining method is evident here. Presently, in the down-dip method, the deterioration of the hangingwall during stoping operations leads to the exposure of sizeable aquifers located in the hanging strata. This results in ingress of water at a rate of approximately 0.4 tons of fissure water
In order to confirm the foregoing sedimentation test results, the selective flocculation tests on artificial mixture of minerals and bauxite ore were carried out. Sodium carbonate and sodium tripolyphosphate were used as dispersants, and sodium polyacrylate (PAAS) was used as flocculant. The test results are presented in Fig. 5 and Table 3.
