Leaching of Al2 O3 From Chemical Desilication Products of Low-grade Bauxite in Chongqing
摘要
Abstract
Leaching of A12 O3 from chemical desilication products of low-grade bauxite in Chongqing was studied .The orthogonal experimental results show that leaching temperature and time are the main influencing factors on leaching rate of A 12 O3 .T he optimal leaching conditions are leaching temperature of 260 ℃ ,alkai concentration of 220 g/L ,CaO dosage of 6% and leaching time of 80 min . Under the optimum conditions ,the average leaching rate of A12 O3 is 85 .70% ,the average relative dissolution rate is 98 .71% .关键词
