Electric Furnace - an overview ScienceDirect Topics

The nodulizing of phosphate rock before it is charged to the furnace improves gas release from the heated furnace charge and decreases dust entrainment in the gaseous furnace products. If fluorapatite (theoretical 3.7%F) forms most of the phosphate rock feed used, this will contain about 2.8% fluoride.

Rock Phosphate Electric Furnace

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.

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.

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.

Polyphosphate Orthophosphate

The furnace process uses heat to develop a highly purified phosphate rock inside an electric furnace to create phosphorous pentoxide. The phosphorous pentoxide is then collected and dissolved in water or a diluted solution of phosphoric acid to produce an even stronger phosphoric acid. This high purity technique is the basic component for the production of orthophosphate generally used for ...

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 bone-ash heating, to electric arc production from phosphate rock.
