Electric Furnace - an overview | ScienceDirect Topics

Electric furnace phosphorus production is relatively tolerant of the impurities present in the poorer grades (lower Ca 3 (PO 4) 2 content) of phosphate rock. A high-silica content in the phosphate rock can be accommodated by a calculated decrease in the proportion of silica fed to the furnace, and the presence of carbonaceous matter may be ...
