·Belt speeds vary from 1 fpm up to 50 fpm for ore and stone and up to 100 fpm for softer and lighter materials such as coal Either a slider plate or idlers may be used to support the belt The belt is usually kept flat with side skirting to retain the material


Bentonite Processing Methods And Required

·Therefore the ore bentonite slurries in the presence of Ca 2 ions had reduced shear forces between particles leading to improved settling rates and grinding performance This is particularly true when the solid percentage of the bentonite containing slurries was 62% or higher than that even at a lower bentonite concentration 5%


The effect of sea water on copper and gold flotation in the presence

·In this study the flotation of a copper gold ore in the presence of 10% bentonite in tap water and sea water was investigated It was found that bentonite had a deleterious effect on copper and gold flotation in tap water but this deleterious effect was mitigated in sea water The bentonite sample is very fine with 70% particles smaller
