Experimental Study of Leaching Yellow Phosphorus Slag by Phosphoric Acid
This paper describes the technology of producing precipitated silica, in which yellow phosphorus slag is leached by phosphoric acid and calcium is separated in form of calcium phosphate monobasic. The experimental results show that optimal technical conditions are: phosphoric acid concentration
31%, reaction time 0.5 hour, stirring speed 400rpm, liquid-solid ratio 5:1 and natural temperature.
Keywords: Yellow phosphorus slag; leaching; phosphoric acid; precipitated silica
