Kaolinite (Al 2 Si 2 O 5 (OH) 4) is the major mineral phase in kaolin ores and is often found, as gangue mineral, in bauxite and iron ores. Direct and reverse flotation are normally applied to recover kaolinite from kaolin ores and kaolin-washing tailings as well as to remove kaolinite gangue from bauxite and iron ores [1], [2], [3], [4].

In contrast to bentonite, increasing kaolin content in Telfer clean ore slightly lowered the flotation recovery, but reduced the copper grade substantially. In Fig. 2 (b) with an increase in kaolin content in the ore from 0 to 25 wt.%, the copper grade decreased from 5% to 2.4% in the first concentrate.

In this investigation, the possibility of physical separation methods such as attrition scrubbing, hydro-cycloning and also reverse flotation were investigated for silica and calcite removal from relatively low grade kaolin. The head sample was provided by the Iran China Clay Company and the major oxides contained in the head sample were …

A kaolin clay from northern Brazil was beneficiated by flotation using an alkylhydroxamate (R6973) as collector. Unlike tall oil fatty acids, this collector does not require activators (divalent cations) for adsorption. Approximately 90% of the particles in the clay sample were finer than 2 μm; therefore, it was a challenge to remove colored ...

Kaolin has important applications in the papermaking, ceramics and other industries. Flotation can remove impurities such as quartz, iron and titanium in kaolin. The flotation methods are as follows: (1) Separation from gangue minerals such as quartz. Using positive flotation method, using dodecylamine, triethanolamine and pyridine as …

Accordingly, a pre-agitating technique followed by high-pressure washing of the sample on a 600 μm sieve were applied. In this method, by discarding up to 20% of the raw material, >54% of the total iron content of the raw kaolin was removed, and the iron content was reduced from 9.75% in the initial sample to <6.00% in the passing fraction.

Kaolin, known as china clay, is a fine white clay with industrial usage. Kaolinite is the most common mineral in kaolin ores and iron, titanoferrous, and carbonate minerals are the major impurities. Calcium oxide (CaO) in carbonate form (CaCO 3) is the recent critical issue for Zonuz kaolin plant located in the North West of Iran.Therefore, a …

Hence the main novelty of this work is the characterization and optimization of the Egyptian kaolin into metakaolin as well as using it as an alkali-activated binder through (i) determining the ideal circumstances for making a highly reactive metakaolin using the Chapelle test; and (ii) examining the mechanical compressive strength (MCS) …
