Electric Arc Furnace Process an overview ScienceDirect
When phosphate rock, phosphorus concentrate, and fluxes are smelted in an electric arc furnace under temperatures of 1400–1500 °C (2552–2732 °F), molten slag is formed and tapped out from the furnace and goes through an air-cooling or water quenching process. The elemental phosphorus is separated from the impurities during the slagging process.

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. The presence of

Furnace Phosphorus and Phosphoric Acid Chemical
Possible alternatives to the electric phosphorus furnace, including the blast furnace and the fuel furnace, as well as other research suggestions, are discussed; from these, a fuel furnace process is distilled that appears to offer the most potential. A scheme for the joint production of phosphoric acid and by-product hydrogen from elemental phosphorus is also appraised. Other possible by

Submerged-arc furnace for phosphorus production
The Submerged-arc furnace for phosphorus production is a particular sub-type of electric arc furnace used to produce phosphorus and other products. Submerged arc furnaces are mainly used for the production of ferroalloys.The nomenclature submerged means that the furnace's electrodes are buried deep in the furnace burden.A reduction reaction takes place near the tip of the electrodes to

US4806326A Phosphate feed material for phosphorus
Nodule fines, formed by abrasion of an electric furnace feed material of phosphate shale nodules, are utilized by mixing a recycle stream of the nodule fines with fresh phosphate in the presence of phosphoric acid prior to forming the shale into nodules. The phosphoric acid prevents loss in mechanical strength of the nodule caused by admixture with the nodule fines.

Mechanical activation of the phosphate rock
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). Table 1.
