Owing to the considerable magnesium content of dolomite and the lack of magnesium in apatite GOFA was selectively chemisorbed onto the dolomite surface. 3 Closed-circuit reverse flotation tests using GOFA as the collector achieved a concentrate with of 28.46 wt P 2 O 5 and 0.65 wt MgO. Moreover the P 2 O 5 recovery was 87.20. Thus GOFA
2020-6-4Solvent Extraction Isotherms. Having explained how solvent extractions can be included in a hydrometallurgical flowsheet and outlined some of the large number of interacting variables to be considered the most basic requirement for solvent extraction design is an understanding of distribution coefficients and equilibrium isotherms

Depression of sphalerite with cyanide and inc sulphate 105 Flotation pH at Rosh Pinah Therefore the presence of hydrophilic inc hydroxide at the surface of sphalerite will prevent the interaction between the lead-activated sphalerite and xanthate and subsequently decrease its floatability in the lead flotation circuit. Figure 7.1

As seen in Table I the dosage ratio of ZnSO4 to NaCN varied from approximately 2.5 to 4. The high dosage of depressant used at Socit Algrienne du Zinc was probably due to the high content of inc 24.3 in the feed
