Soluble

The roasted ore produced by the fluidized roasting of high-iron sphalerites characterized by high soluble iron and low soluble zinc and is not applicable in wet metallurgy.

针对高铁闪锌精矿沸腾焙烧产出的焙砂可溶铁含量高、可溶锌率低,不符合湿法冶炼锌工艺要求的问题,借鉴闪锌精矿沸腾焙烧技术操作条件,通过工业化试验研究,寻找炉温、风料比、烟气出口抽力、入炉精矿中铁含量、炉料在炉内停留时间等焙烧技术条件与焙砂中可溶铁、可溶锌等之间的关系,确定适合于高铁闪锌精矿焙烧的技术操作条件。

The concentration of soluble iron extrated from sediments is controlled by three major factors as follows:1.
