Orthogonal Experimental Study on Sulfuric Acid Leaching of Alkali-Decomposed Tungsten Slag AITranslate
Abstract AITranslate
The L25(56)orthogonal test was used to study the effects of sulfuric acid concentration,liquid-solid ratio,leaching temperature,stirring speed,reaction time and tungsten slag particle size on the tungsten leaching rate in the sulfuric acid leaching process of alkali-decomposed tungsten slag,and the experimental results were analyzed.The results show that the significant factors affecting the tungsten leaching rate are in the descending order of leaching temperature,sulfuric acid concentration,tungsten slag particle size,liquid-solid ratio,stirring speed and reaction time.The optimum conditions for tungsten leaching are leaching temperature 40℃,sulfuric acid concentration 20%,tungsten slag particle size 75~150μm,liquid-solid ratio 20∶1,stirring speed 250 r/min and reaction time 1.5 h.Under the optimum conditions,the tungsten leaching rate can reach 91.63%.This study can provide a reference for optimizing the sulfuric acid leaching process of alkali-decomposed tungsten slag.
