Method for wet-process gradient desulfurization of manganese slag
The invention discloses a method for wet-process stepped desulfurization of manganese slag, which comprises the following steps: carrying out size grading on manganese ore, leaching, purifying a solution, filtering and the like, carrying out size grading on the obtained manganese slag to obtain coarse-grain manganese slag and fine-grain manganese slag, carrying out phase conversion of calcium sulfate part on the fine-grain manganese slag, and carrying out fine-grain floc flotation to obtain the wet-process stepped desulfurization of the manganese slag. And then the coarse-grain manganese slag and the low-sulfur tailings are mixed, and the low-sulfur manganese slag is obtained. The low-sulfur manganese slag prepared by the method can be used as a raw material for preparing cement clinker, the high-sulfur manganese slag can be used as a cement retarder, the method realizes recycling of the slag in the electrolytic manganese production process through a physical means, the process is simple, secondary pollution is not generated, and the method has a good industrial application prospect.
本发明公开了一种锰渣湿法梯级脱硫的方法，通过将锰矿石进行粒度分级并进行浸出、溶液净化、过滤等处理，将得到的锰渣进行粒度分级，得到粗粒锰渣和细粒锰渣，再对细粒锰渣进行硫酸钙部分物相转化细粒絮团浮选，获得低硫尾渣和高硫锰渣，随后将粗粒锰渣和低硫尾渣混合，得到低硫锰渣。本发明所制得的低硫锰渣可作为制备水泥熟料的原料，高硫锰渣可作为水泥缓凝剂，本发明的方法通过物理手段实现电解锰生产过程中渣的资源化，流程简单且不产生二次污染，具有良好的工业应用前景。
