Rock Phosphate Electric Furnace

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 allowed for by decreasing the coke.

rock phosphate electric furnace - comonoosa.com.au

Phosphate rock Phosphate rock, which usually contains calcium phosphate, was first used in 1850 to make phosphorus, and following the introduction of the electric arc furnace by James Burgess Readman in 1888 (patented 1889), elemental phosphorus production switched from the boneash heating, to electric arc production from phosphate rock.
