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.

Recovery of uranium from slag from the electric furnace

2018-8-15  When phosphate rock Is reduced to elemental phosphorus with coke In the electric furnace process, the uranium In the phosphate rock virtually all goes Into the by-product slag. It Is estimated that approximately 300 tons of uranium is potentially recoverable per year from this use of phosphate rock.

Mechanical activation of the phosphate rock

2009-8-9  rock is treated in an electric furnace to produce a very pure and more expensive phosphoric acid (frequently called white or furnace acid). In the wet process, the phosphate rock was treated with acid producing phosphoric acid (also called green or black acid) and gypsum, which is removed as a by-product (Maene, 1999).
