在投矿量为２００ｇ／次和１ｋｇ／次的规模下，进行了机械活化苏打溶液分解柿竹园白钨中矿的试验研究。结果表明，在苏打用量为理论量３倍、１８５～１９５℃保温１．５ｈ的条件下，连续２０次分解，渣含不溶ＷＯ＿３平均为０．２５％，钨平均分解率为９８．６％；在苏打用量为理论量２．５倍、２０５℃保温１．０ｈ的条件下，钨分解率为９８．４％。５ｋｇ／次规模下试验结果表明，钨分解率可达９８．３％。 Under the scale of 200g / time and 1kg / time, the experiment of mechanical activation soda solution decomposition of Shizuyuan scheelite mine was carried out. The results showed that when the amount of soda was 3 times the theoretical amount and the temperature was kept at 185 ~ 195 ℃ for 1.5h, the average decomposition rate of WO3 was 0.25% and the average decomposition rate of tungsten was 98.6%. When the amount of soda is 2.5 times the theoretical amount and the temperature is kept at 205 ℃ for 1.0h, the decomposition rate of tungsten is 98.4%. 5kg / sub-scale test results show that the decomposition rate of tungsten up to 98.3%.
