ON USING EXCESS GIBBS ENERGY AS AN INDICATOR OF HYDROPHOBICITY IN THE FLOTATION PROCESS [PDF]

open access: yesSustainable Extraction and Processing of Raw Materials Journal, 2022
. It has been shown that the partial molar excess Gibbs energy (G̅ex) can be used as an indicator of hydrophobicity and hence contributes to explaining the behaviour of collectors in the recovery of minerals by flotation.

An approach to the evaluation of froth flotation reagents based on the use of the SWARA and WS-PLP methods [PDF]

open access: yesMining and Metallurgy Engineering Bor, 2017
The selection of the most suitable flotation reagents is very important in the froth flotation process because the recovery of valuable minerals largely depends on the reagent regime. On the other hand, the particular characteristics of the ore excavated
