Frontiers | Algal removal from raw water by electro-flotation
In order to reduce the influence of algae on the conventional treatment process of the water plant, the electro-flotation process was used to test the raw water of a lake-type reservoir. After raw water with cyanobacteria as the dominant algae is treated by the best electro-flotation process, the average removal rate of algal density can reach …

Micro-bubble flow simulation of dissolved air flotation process for
The process efficiencies between the cyclonic state micro-bubble flotation column (FCSMC) and dissolved air flotation column (DAF) were compared. Results show that this FCSMC has higher oil removal efficiency and treated water with lower oil levels than the DAF, especially for the process of fine oil droplets (<10 μm).

Modelling for froth flotation control: A review
1. Introduction. Froth flotation is the largest tonnage separation in mineral processing by which valuable mineral is separated from waste rock. Advances in control and optimisation of the froth flotation process are of great relevance since even very small increases in recovery lead to large economic benefits (Ferreira and Loveday, 2000, …

The use of enrichment ratios to support kinetic studies in flotation
Abstract. This paper presents the use and evaluation of enrichment ratios (ER) from different batch flotation protocols. Two protocols under flotation time extensions (>20 min) are analysed, which favour steady recoveries to be obtained at the end of the process. Agar's criterion is used to evaluate the consistency between the maximum ...

The paper by Broadhurst et al. is the only study primarily addressing the flotation process (Broadhurst et al. 2015). In their analysis, they evaluated the impacts of desulphurisation of base metal sulphide tailings, via froth flotation, to reduce acid rock drainage (ARD) and at the same time to obtain valuable by-products.

An overview of reverse flotation process for coal
Flotation is one of the most effective technologies for the up-gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal. Contrary to this, reverse flotation of coal in which coal particles are depressed and gangue particles floated, was developed as an alternative process to minimise the sulphur …

Notes on Method of Froth Floatation
Switch flotation method – Gunge sticks to the air pocket, and metal particles tumble to the base. This is the way it works. How froth floatation works. Some of the minerals in the ore are picked up by a liquid film and floated on top of a mass of fluid pulp. This process, called floatation, separates the valuable minerals from less valuable ones.
