Here we report the efficacy of an ion flotation process that uses the biosurfactant monorhamnolipid as a metal collector to recover Cs+, Cd2+, and La3+ from water. These elements were tested at collector-to-colligend ratios of 2, 5, and 10. The collector-to-colligend ratio and metal valence play a large role in determining flotation success ...

Figure 7. Grade-recovery curve of the Gonçalo lepidolite froth flotation. Similarly to what occurred with spodumene, it was not possible to obtain concentrates with Li 2 O grades close to the Gonçalo lepidolite Li 2 O content (5.58 % Li 2 O [31]), even after the cleaning stage, having been 4.50 % Li 2 O the maximum value achieved. The shape of the grade-recovery curve indicates …

A new kinetic model for Ni(II) ion flotation based on gene ...

The present study aims to develop a simple, rapid and economic procedure for copper(II) and lead(II) removal under the optimum conditions investigated. It is based on the complex formation between Cu2+ and Pb2+ ions and diphenylcarbazone (HDPC) followed by flotation with oleic acid (HOL) surfactant. The different parameters (namely: solution pH, HDPC, HOL, copper …
