Nov 10, 2021The mechanism for flotation separation was also discussed. The results showed that the ore was a fine-grained calcareous-siliceous collophanite with high P2O5 grade. The gangue minerals such as quartz, sericite (muscovite), pyrite, and dolomite were finely disseminated and encapsulated by fluoroapatite particles in a rather complex relationship.

"In this work, Chitosan-grafted-Polyacrylamides (Chi-g-PAMs) were studied, for the first time, as selective depressants of pyrite in the flotation of base metal sulfides. Fundamental studies of the adsorption behavior of Chi-g-PAM on model sulfide minerals indicated that Chi-g-PAM was more selective to pyrite's surfaces as compared to base metal sulfides. Results suggested that the ...

Effect of ultrasound on separation selectivity and efficiency of flotation

Since the pyrite content of the ore is very high (∼49%), the flotation behaviour of pyrite has very important effect on grade of concentrate. As can be seen from Fig. 2, quality of the concentrates is proportional to the drainage rate of pyrite from the froth to the pulp. It appears that pyrite and/or non-sulphide gangue minerals can ...
