THE INFLUENCE OF FROTHER IN FLOTATION USING ELECTROLYSIS FOR BATIK DYEING WASTE SEPARATION [PDF]

, 2016
Batik waste can increase water characteristics such as turbidity, color and Total Suspended Solid (TSS). A technique for separating Batik from the liquid so that its turbidity, color and TSS decrease is needed. Flotation studies have been conducted using

Pico–nano bubble column flotation using static mixer-venturi tube for Pittsburgh No. 8 coal seam

International Journal of Mining Science and Technology, 2015
The flotation process is a particle-hydrophobic surface-based separation technique. To improve the essential flotation steps of collision and attachment probabilities, and reduce the step of detachment probabilities between air bubbles and hydrophobic ...

Recovery of pyrite from copper tailings by flotation

Journal of Materials Research and Technology, 2019
Tailings that are generated in the copper concentrate production contain great amount of sulfide mineral, in particular pyrite. Pyrite in contact with water and oxygen might oxidize spontaneously and originates a serious environmental problem.

Quantitative Evaluation of Frother Blend Interaction and Its Effect on Coal Flotation

, 2013
In this investigation the weak and powerful frothers, like methyl isobutyl carbinol (MIBC) and polyethylene glycol-600 (PEG) were used for studying the surface tension of frother blends at various concentrations.

The influence of frother types and concentrations on fine particles' entrainment using column flotation

, 2017
Entrainment which is the characteristic feature of fine particles is closely related to water recovery. It is based on the changes depending on the establishment of linear relationship between water recovery and solid recovery.

Mechanical flotation of hydrophilic particles in the presence of frother [PDF]

, 2007
W artykule zaproponowano metodę oceny zdolności spierniaczy flotacyjnych do wyniesienia mechanicznego ziaren podczas przepuszczania powietrza przez zawiesinę ziarn hydrofilnych. Polega ona na pomiarze wyniesienia mechanicznego ziarn w komorze flotacyjnej
