Primary smelting can be carried out in a reverberatory, rotary, or electric furnace. The choice depends more on economic circumstances than on technical considerations (3). Thus, in the Far East, reverberatory furnaces fired with anthracite coal as the reductant were and still are widely used. 

Ca.rhothermic Reduction. Sihcon carbide is commercially produced by the electrochemical reaction of high grade siUca sand (quartz) and carbon in an electric resistance furnace. The carbon is in the form of petroleum coke or anthracite coal. The overall reaction is...

There are two major types of filtration "cake" and "filter-medium" filtration. In the former, solid particulates generate a cake on the surface of the filter medium. In filter-medium filtration (also referred to as clarification), solid particulates become entrapped within the complex pore structure of the filter medium. The filter medium for the latter case consists of cartridges or granular media. Among the most common examples of granular materials are sand or anthracite coal.

Titanium in Plants and Animals. In 1896 C. E. Wait found large amounts of titanium in the ashes of bituminous and anthracite coals, oak wood, and apple and pear wood (23, 57). L. G. Willis, in his bibliography on the minor elements in plant and animal nutrition, gave several references to the presence of small amounts of titanium in soils, in plants, and in the human body (58). 

Detonable cartridges are prepd by sheathing insensitive expl cores with sensitive expls. The method makes possible the deton of any metal-nitrate mixts and of molded, pressed, or caked AN-based expls. For example, a core of 85% NaNC>3 15% ground anthracite coal of density 1.38g/cc becomes easily detonable when enclosed in a sheath of 40% Dynamite of density 1.01) Ad 109) E.
