Gold and Silver Processing

EFD has a number of industry-leading flotation products for processing gold. This includes the HydroFloat, a state-of-the art flotation unit that uses fluidization to selectively float coarse and high SG gold particles that cannot normally be concentrated using flotation. We also have a range of air sparging products, including the SlamJet™ and the CavTube™ which greatly improve the kinetics of cyanide leaching by producing fine bubbles with high oxygen mass transfer to the leach solution.

Fertilizer Minerals

These technologies incorporate improved methods of air sparging and particle contacting for coarse, fine, and ultra-fine particles. For the coarsest particles, the Eriez HydroFloat Separator is a proven process for the recovery of particles up to and exceeding 4-mm. Fine particles are best treated using EFD's proprietary SlamJet sparging system. For ultra-fine particles or where more intimate contacting is required, the CavTube™ sparging system can be employed.
