• New approaches iN gold recovery, TechNical bulleTiN

    conventional flotation such as flash flotation, which is often used in gold flowsheets, is only effective for part¬icles less than about 100 microns, and flotation is complicated when free gold and gold bearing sulfides are present together. This is further complicated by the ubiquitous

  • The role of a flash flotation circuit in an industrial ...

    The distribution of valuable material in the cyclone overflow stream (conventional flotation feed) undergoes a step change when the flash circuit is taken offline with an increase in the amount of valuable fines being generated, which is further reflected in the flotation tails with a higher proportion of both pyrite and gold being present in the intermediate and fine size classes.

  • flash flotation process

    Flash flotation is the instantaneous flotation of fast floating valuable mineral particles from the grinding circuit to produce a suitable grade concentrate. A flash flotation cell recovers liberated valuable minerals in the cyclone underflow (recirculating load) before they return to the mill for further grinding.
