Before flotation, carbonate phosphate ores are generally subjected to attrition scrubbing, desliming, and classification to remove the fine particles, carbonates, silicates, and clays (Boujlel et al., ... It can be concluded that the flotation time is an important factor combined with the pH of the pulp in the flotation tests.
A Wemco laboratory flotation machine (71260-01) was modified for attrition scrubbing by fixing three propeller tiers with alternating handedness (right-left-right) to the rotating shaft within an octagonal agitation cell. LCD screen shredder residue was split into roughly 600 g samples for attrition scrubbing by a Jones riffle splitter.
After attrition scrubbing, the washing efficiency of the original state lead contaminated sand soil in triplicates was 67.61%, 31.71% and 41.01%, respectively, which indicates that attrition ...
is to assess the economic importance of beneficiation and the selection of the economic beneficiation method. Direct leaching, attrition scrubbing, leaching, and flotation and leaching were investigated economically. Attrition scrubbing method is given as an example because it is generally used in the pre-beneficiation

This preliminary study explored a novel approach to enriching unexploited low-grade phosphate washing sludge (PS) using a combination of attrition scrubbing, desliming, and reverse flotation.By employing a Box-Behnken experimental design (BBD) and response surface methodology (RSM), the study optimized flotation parameters …
Recycling spent batteries to recover their valuable materials is one of the hot topics within metallurgical investigations. While recycling active materials (Li, Co, Ni, and Mn) from lithium-ion batteries (LIB) is the main focus of these recycling studies, surprisingly, a few works have been conducted on the other valuable metals. Copper and aluminum …
In this study, direct leaching, attrition scrubbing and leaching, and flotation and leaching methods are evaluated economically based on the data for the Mountain Pass (MP) facility.
This preliminary study explored a novel approach to enriching unexploited low-grade phosphate washing sludge (PS) using a combination of attrition scrubbing, …
The surface confinement of indium on LCD screen glass enables the beneficiation of indium via attrition scrubbing. Attrition scrubbing of LCD screen shredder residues is a low-cost process over which a high degree of control can be imposed ultimately leading to the production of a higher concentration indium product which may …
Attrition scrubbers may not be glamorous, but they are an important and sometimes neglected step in mineral processing. Optimal attritioning will significantly improve the results and efficiencies of subsequent processing steps and can lead to reduced costs and improved product yields. Why is attrition scrubbing used? Attrition …
ABSTRACT In this study, we investigated the effect of the scrubbing medium's particle size distribution on the scrubbing flotation performance of microcrystalline graphite. A simplex lattice mixture design approach using Design-Expert software was employed for proportioning testing of the scrubbing media. Three different …
ABSTRACT This work aimed to upgrade a low-grade sedimentary phosphate ore through attrition scrubbing/desliming and an anionic/cationic reverse flotation technique. The mineralogical and chemical examination showed that the sample contained low-grade apatite minerals (P2O5 ~ 22.5%), and the main associated gangue …
Two-stage scrubbing as practiced in sand-plants, to liberate bituminous or carbonaceous matter and clays in the production of specification sand. Potash crystals where clay must be disintegrated prior to washing, and where removal of slime coatings greatly improves or is essential to flotation recovery. Polishing sand grain surfaces to remove ...
Attrition scrubbing of the crushed ores was found to be an unconventional process, not only for fine talc production, but also for proper separation of the harder carbonaceous gangue. Talc pre-concentrates, less than 0.074 μm, were prepared by attrition scrubbing in the laboratory having 8.40% L.O.I. with a yield reaching 74.70%.
In this work, scrubbing parameters (i.e., scrubbing medium's particle size, stirring speed, and solid concentration) were optimized via response surface methodology using Box-Behnken design to yield the maximum enrichment efficiency of graphite ore. The scrubbing medium's particle size was found to be the most important influencing factor.
Applications for attrition scrubbers. Flotation – cleaning particle surfaces prior to flotation to increase selectivity. Glass sand – removing iron oxide coating on silica sand by attrition and flotation to produce a low-iron glass sand.
Whether you want to remove surface contaminants, scrub sand-sized particles, increase durability, improve turbidity and/or sand equivalency, or prepare flotation feeds and reagent washing, Attrition Cells can provide the aggressive scrubbing action needed to remove clays and other contaminants that can harm a final product.
Scrubbing aims at placing in suspension the ensemble of solids in the material to be processed, often clayey or relatively unconsolidated, through actions involving the dispersion of constituents by means of deconsolidation and disintegration. It also brings about a more or less extensive surface cleaning of the elements, or the placing in …
