Extraction of Alumina from Local Clays by Hydrochloric

period and temperature of extraction. The production of a crude alumina from clay was also investigated on a pilot plant scale[12]. Weston described in several patents[13] the production of a purified alumina-silica product and substantially pure aluminum chloride from iron-containing bauxites, bauxitic clays, kaolinitic clays and mixtures thereof.

11.25 Clay Processing

kaolin, ball clay, fire clay, bentonite, fuller’s earth, and common clay and shale. Kaolin, or china clay, is defined as a white, claylike material composed mainly of kaolinite, which is a hydrated aluminum silicate (Al2O3·2SiO2·2H2O), and other kaolin-group minerals. Kaolin has a wide variety of industrial

5 Aggregate Production IN.gov

CRUSHING The first step of processing begins after the extraction from quarry or pit. Many of these steps also are common to recycled materials, clay, and other manufactured aggregates. The first stag e in most operations is the reduction and sizing by crushing. Some operations, however, provide a step prior to crushing called scalping.
