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

Effects of Flotation Reagents on Flotation Kinetics of Aphanitic (Microcrystalline) Graphite
Separations, 2022 The flotation method is widely used for the preliminary beneficiation of aphanitic (microcrystalline) graphite. However, there is limited literature regarding the effects of flotation reagents on the flotation kinetics of aphanitic graphite. In this study, six commonly used flotation kinetic models were used to fit the flotation experimental data of ...
