Abstract
1500070 Glass batch constituent DYCKERHOFF ZEMENTWERKE AG 17 July 1975 [20 July 1974] 30079/75 Heading CIM A calcium silicate-containing material is used as a batch constituent in producing molten glass, the calcium silicate-containing material having been obtained by removal of a fenophosphorus-containing phase from the slag obtained during the electrothermal extraction of phosphorus from a crude calcium phosphate. The said electrothermal process comprises reacting calcium phosphate, coke and silica so as to form phosphorus and carbon monoxide (in gas form), leaving a residual slag comprising the calcium silicate phase and a fenophosphorus phase. The molten slag may be quenched with water so that the fenophosphorus phase is selectively granulated, this phase then being removed by classification, by sorting, or by magnetic separation. The crude calcium phosphate used may be apatite or fluoropatite.
