Abstract
Calcium aluminate is produced by heating coarsely crushed bauxite and limestone at a temperature such as not to cause fritting, for instance in a rotary furnace, and then fusing the mixture in a second furnace. The fused product may be granulated in water. The first heating may be effected by gases from the second furnace. The Specification as open to inspection under Sect. 91 (3) (a) states that alternatively a blast furnace may be employed, the p charge consisting of alternate layers of red bauxite (which may contain 32-35 per cent of ferric oxide) mixed with limestone and of coke. The aluminate is recovered as a liquid slag and the iron as pig iron. In another modification, a converter is employed. It is charged with pellets of a mixture of bauxite, limestone, and coke dust upon a bed of kindled coke. An agglomerated mass of crude aluminate is obtained, which is discharged by tilting the converter. This subject-matter does not appear in the Specification as accepted.
