摘要
针对攀西地区丰富的钛资源现状和现行富钛料生产工艺优缺点,提出了微波加热还原钛精矿复合球团-选矿分离-微波浸出制取高品质富钛料的新工艺路线.同时测定了复合球团的升温曲线;确定了复合添加剂的用量为5%~6%;选矿分离时磨矿时间为20 min的工艺条件.在此条件下,对整个工艺流程进行了实验研究,得到了纯度为96.08%的富钛料.
A new technology for preparing rich titanium product, which includes microwave reduction - mineral separation - microwave leaching, was put forward on the basis of the abundant situation of titanium mineral resource in Panzhihua - Xichang zone and the advantages and disadvantages of actual productive methods on making rich titanium product. The heating curve of self - reduced pellet of titanium concentrate was measured. The appropriate technological parameters including the rain were determined. Experiments were conducted on rich product was 96.08 % under the above condition. content of additive 5 % - 6 %, the milling time of 20 the whole flow sheet and the TiO2 content in titanium
