Adsorption and Flotation Characteristics of the Different Types of Frothers

Abstract

This article investigates the adsorption of different frothers onto talc particles. The adsorption and flotation characteristisc of tallow amine acetate (TAA) þ frothers (MIBC and pine oil) was studied for talc mineral. In this study, we analyzed some parameters affecting froth flotation performance and it was determined that adsorption capacity in particular, had an important role in froth flotation enrichment. The effect of pH and adsorption time on adsorption capacity was also studied. Analyses were carried out using ultraviolet spectrometry. The results showed that MIBC had the lowest frother adsorption capacity and it improved recovery during froth flotation of on the talc. It can be said that MIBC was adsorbed on the talc surface less and provided the best conditions to generate bubbles in flotation cell.

Talc Flotation—An Overview

“…A cleaved talc surface is considered to have a very low root mean square roughness, which indicates a very smooth surface. This cleaved surface becomes very hydrophobic, as manifested in the contact angle measurement [10][11][12]37,40,41].…”

“…Frothers such as alcohols can adsorb on the mineral's surface by using their hydroxyl group; thus, they are analogous to talc depressants such as starch, cellulose, and dextrin (their molecular structure includes alcohol groups) [84]. However, lower frother adsorption onto the talc surface would be desirable through separation since flotation water reduced the surface tension [12]. Methyl isobutyl carbinol (MIBC) as a typical frother could enhance its flotation recovery because of its collecting capability [85].…”

“…The talcum powder is used as a cosmetic [4,6,8,11,13,14] Color and Paint • Medium purity is used in paint. It can be utilized as a filler material and extender [5,6,[10][11][12][13] Paper…”

“…It is also used as a filler material, extender, and structural immobilizer. [5,6,8,9,12,13,15] Roofing…”

“…Nevertheless, in highly saline media, the bubble size is influenced mainly by inorganic electrolytes, and the frother has only a minor effect (Laskowski, Castro, and Ramos, 2014). This is an important issue, considering that frothers might adsorb onto the hydrophobic mineral surfaces, decreasing their floatability (Kursun, 2014). …”
