Abstract

1299797 Treatment of diatomaceous earth or perlite HOKURIKU CHEMICAL MACHINERY CO Ltd and SAIKA TEXTILE MFG CO Ltd 2 April 1970 [29 Nov 1969] 15630/70 Headings C1A and C1M Diatomaceous earth or perlite is treated by roasting with HCl, H 2 SO 4 or mixtures thereof at 100‹ to 500‹ C. Thereby insoluble metal salts such as Fe 2 O 3 , Al 2 O 3 are converted into soluble chlorides or sulphates.
