phosphate rock fines for the electric furnace The fines must be sintered and then crushed to size and screened The ore is screened to remove oversized material Another agglomeration method is nodulizing In this process, phosphate fines are heated in a rotary kiln to incipient fusion The tumbling in the kiln causes the material to cohere and form spheroidal agglomerates A final method of
A method used for the production of elemental phosphorus, according to the electric furnace method, in which crushed fosfaatlei-stone ore is pressed into forms which is calcined to obtain a furnace feed material of calcined fosfaatbolletjës, 5 which is formed with fine fabrics by abrasion of the phosphate spheres, with characterized in that
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
The silica added to the furnace charge behaves as a strong acid at a high temperature, about 1500°C, and combines with the calcium constituent of the phosphate rock to form calcium silicate ( Schipper et al, 2001; Joseph, 2008;Mark, 2011 In the second stage, the elemental phosphorus is oxidized with air to become phosphorous pentaoxide (P 2 O
