  • New Technology To Improve The Recovery Of Fine Particles

    abstract new technology has been developed to improve the selective recovery of fine particles in the froth flotation process. the technology is based on using hydrophobized glass bubbles as a carrier material for hydrophobic fine particles, which promotes selective particle agglomeration. proof of concept was carried out using fine graphite particles in order to validate grinding particle size. both large ore particles and small ore particles affect flotation efficiency and mineral recovery. In the case of flotation coarse particles, due to the heavyweight, it is not easy to suspend in the flotation machine, and the chance of collision with the bubbles is reduced.

    thus, the froth recovery calculated here was in very good agreement to that reported by alexander et al. for a If the gold is combined with the copper than if your current grade is 0.8 gt to raise this you need to reduce the overall recovery, and lose copper. If the gold is separate than you need to adjust the scavenger and re-cleaner circuits to get more recovery of the gold by adjusting the reagents.
