Abstract

Alkali chromates are obtained by treating hromium ores in the presence of basic filling materials such as dolomite with a mixture of 75-25 per cent of alkali carbonate and 25-75 per cent of alkali sulphate. In examples temperatures of 1050-1100 DEG C. are used and reaction is effected in rotary or muffle furnaces. Alkali sulphate obtained in bichromatizing the chromate liquors may be used in the process. Specifications 4028/84 and 18218/00, [both in Class 1, Acids, alkalies, &c.], are referred to.
