The issue of clay processing concerns both provenance and techno-functional ceramic investigations. In the former, the compositional/textural modification of clay alters the petrofacies expressed by the ceramic body and causes a change from the raw material in terms of bulk chemical and mineralogical composition and petrographical features as …

Soil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class. Soil texture influences nearly every aspect of soil use and management. Many of the physical and chemical properties of the soil depend on how fine (clayey ...

Abstract. There are two main types of methods of processing glass, those involving stock removal or grinding and non-grinding methods. In the latter, the glass is made plastic and heated above its transition point, while in the stock removing methods particles of glass are broken off with the material in the cold state.

There are two basic methods of processing kaolin, a dry method or a wet process (Guillet and Kriens, 1984). The dry method is called air flotation which separates the clay from contaminants. The wet method produces water washed clay where the clays are fractionated, beneficiated or otherwise modified from their orig- inal state.
