以硫酸渣为原料制备铁红工艺研究

THE RESEARCH OF MAKING IRON RED FROM SULFURIC ACID SLAG

本文报导了以硫酸渣制备的铁盐溶液为原料制备铁基颜料之一──铁红的研究结果。提出并研究了空气氧化分离铵黄铁矾制备高挡铁红颜料的工艺路线，初步确定了一些主要工艺参数。这种以硫酸渣为原料制备高挡铁红的工艺尚属首次报导。

This paper reports the research resulf of making the iron red that is one of iron─base colorants.This iron red is made from the ferriferous solution that is made from sulfric acid slag.This process of the iron red that is made from sulfuric acid slag is first reported.
