The Art of Talc Flotation for Different Industrial Applications

Abstract

Talc has found a steadily increasing number of uses such as cosmetics, steatite and cordierite ceramics, for pitch control in the paper industry and as a reinforcing filler in rubber, etc. In this research, the amenability of some Egyptian carboniferous finely disseminated talc ores to beneficiation by flotation was investigated on laboratory scale. The original talc sample is characterized by low MgO content (

“…The concentrate was characterized to monitor the extent of talc recovery and iron removal efficiencies. The mass and component recoveries of concentrate were determined (Ahmed, 2017;Boulos et al 2016). The concentrate obtained was further used for the leaching investigations.…”

“…The experimental mass and component recovery of the concentrate after flotation is determined through the following relations (Boulos et al 2016):…”

“…The chemical analysis of samples showed that, iron oxide was the main gangue mineral in samples (the percent of Fe 2 O 3 = 4.96%). Boulos et. al.…”

“…For El-Allaqi sample, an attritioning scrubbing was executed at 60% solids, 2100 rpm motor speed and an attritioning time of 60 minutes. The product has 5% loss on ignition and about 87.5% mass recovery (Boulos et. al.…”

“…Flotation is the preferred concentration technique to remove impurities from talc Kho and Sohn, 1989). Various factors that control the flotation process of talc include particle size, pH values, collector dosage, depressant dosage, pulp density and frother dosage which were studied by many authors (Fuerstenau and Huang, 2003;Boulos et. al.…”
