Evaluation of hematite and quartz flotation kinetics using surfactant produced by Rhodococcus erythropolis as bioreagent [PDF]

open access: goldREM: International Engineering Journal, 2019
The use of biosurfactants as reagents represents a promising alternative to the conventional surfactants used in the mineral industry because they may present low toxicity and high biodegradability.

Proposing a seven-parameter kinetics model for predicting cerussite flotation recovery [PDF]

open access: greenInternational Journal of Mining and Geo-Engineering, 2020
Sulfide lead resources are being depleted and the exploitation of carbonate lead deposits is now the main focus of lead mining. Cerussite, PbCO3, is majorly discarded to tailing damps because it is difficult to be processed by flotation in lead ...

Effect of Solid Concentration and Particle Size on the Flotation Kinetics and Entrainment of Quartz and Hematite [PDF]

open access: goldMetals, 2022
Despite the importance of solid concentration in froth flotation, its effect on flotation kinetics and entrainment has rarely been studied. In this study, the flotation kinetics and entrainment in quartz and hematite single-mineral flotation systems as a

Effects of Flotation Reagents on Flotation Kinetics of Aphanitic (Microcrystalline) Graphite

open access: yesSeparations, 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.

Local and global assessment of flotation kinetics [PDF]

open access: yesE3S Web of Conferences, 2016
Most flotation data can be approximated with the first order kinetic equation. However, this equation frequently provides two, not one, parameters, that is the first order flotation rate constant k and maximum flotation recovery Rmax. Currently, the most

A new mathematical model for coal flotation kinetics

open access: diamondDyna, 2017
This study describes the development and formulation of a novel mathematical model for coal flotation kinetic. The flotation rate was considered as a function of chemical, operating and petrographic parameters for a global flotation order n. The equation

Derivation of Flotation Kinetic Model Combining Surface Property Analysis and Kinetics

open access: goldJournal of MMIJ, 2022
Copper sulfide minerals are the major raw materials for copper products. Copper sulfide minerals are mined at copper mines and concentrated by flotation process. In recent years, the mining of refractory copper ores, which is difficult to concentrate by flotation due to their fine grain size, presence of multiple copper mineral species, and fluctuation
