ABSTRACT:
Liquid phosphorus as produced by the reduction of a phosphate ore in an electric arc furnace while of high purity contains color-causing impurities that impart to the phosphorus a black color by reflected light. Such liquid phosphorus is polished or refined to exhibit a yellow or yellow brown cast by mixing it with hot water and subjecting the mixture to intense agitation. The refined phosphorus is separated from the water phase which retains the impurities.
