简介:以CaSO4制备得到的CaS为还原剂,研究氧化锰矿的还原-酸浸过程,考察硫化钙与矿石的质量比、还原温度、还原时间、液固比、搅拌速率、浸出温度、浸出时间和H2SO4浓度对氧化锰矿中锰及铁浸出率的影响。结果表明:优化的还原工艺条件为硫化钙与矿石质量比1:6.7、液固比5:1、搅拌速率300r/min、还原温度95°C、还原时间2.0h;酸浸工艺条件为搅拌速率200r/min、H2SO4浓度1.5mol/L、浸出温度80°C、浸出时间5min。在此优化条件下,锰的浸出率达到96.47%,而铁的浸出率仅为19.24%。该工艺可以应用于不同类型氧化锰矿中锰的提取,且锰的浸出率均高于95%。
简介:在一种零件上设计有许多对称相同的弯曲结构件,采用斜楔式顺序弯曲模一次弯曲成形。侧弯曲凸模在侧弯曲凸模凸轮压块的楔面作用下顺序进入凹模冲压成型。然后在凸轮滑动块拉杆的作用下带动侧弯曲凸模凸轮滑动块滑动,使侧弯曲凸模在弹簧作用下复位。
