Recovery Of Chrome From Ore By Flotation. The theoretical grade-recovery curve for an ore is a definition of the maximum expected recovery by flotation of a mineral or element at a given grade. This is defined by the surface area liberation of the value minerals and is consequently directly related to the grind size utilised in the process.

recovery. This was accomplished by installing a chrome extraction plant in the middle of the flotation circuit in order to benefit the increase in PGMs recovery from secondary circuit by lower tonnage to the mill, hence more residence time and better grinding results. The results obtained indicate that the
Apr 04, 2021 Rougher flotation of ore containing abundant olivine upgraded the chromite from 23.4 to 29.6 percent Cr2O3 at a recovery of 89.4 percent. How to Recover Chromite The objective of flotation studies was to improve the overall chromite recovery by flotation of chromite in the slimes from the gravity concentration circuit.
Aug 19, 2008 This is followed by flotation banks comprising 10 cleaner and five recleaner cells that take the concentrate recovery level of about 44% of the contained PGMs. Collector reagents are used to make the PGMs aerophilic, depressors are used to make the chrome hydrophilic, in addition to the frother.
