Abstract

1,269,344. Treating slags. RHEINISCHE KALKSTEINWERKE G.m.b.H. 18 Aug., 1969 [12 Dec., 1968], No. 41078/69. Headings C1H and C1K. Water quenched granulated slags from phosphorus production are purified by separating out the 0-0À2 mm. fraction. The purified slag can be ground with cement clinker to form a cement of low iron oxide, or used as an additive in sand and lime bricks.
