01-01-2015· The effect of serpentine and quartz on the flotation of pyrite at pH 9 is shown in Fig. 2.It can be seen from the picture that serpentine particles interfere with flotation of pyrite and their effect is related to their size, the finer the serpentine slime is, the lower the pyrite recovery will be.
The Effect of Sodium Alginate on Chlorite and Serpentine,
Chlorite and serpentine are common magnesium-containing gangue minerals in copper sulfide flotation. In this study, sodium alginate, a natural hydrophilic polysaccharide, was introduced as a selective depressant for these gangue minerals. Micro-flotation tests were conducted on both single minerals and synthetic mixtures. The flotation results showed that sodium alginate
