中文摘要: 氧压浸锌是一种新兴的湿法浸锌工艺，工艺过程中将会产生40%高硫渣，由于高硫渣的颗粒不均匀，黏度大，工艺矿物学研究不深入，导致高硫渣的处理和利用难度大。以内蒙某锌冶炼厂的高硫渣、硫精矿、硫尾矿为研究对象，研究其工艺矿物学特性，以及有价金属铅、锌、铜、银等综合回收利用。采用XRF、偏光显微镜、SEM-EDS、激光粒度分析仪和MLA矿物解离分析仪等测试分析方法，探究高硫渣、硫精矿、硫尾矿的元素和矿物组成、粒度和矿物连生情况。高硫渣浮选硫回收率84.5%，硫尾矿投入奥斯麦特富氧顶吹炉铅冶炼系统后，Pb、Zn、Ag的回收率分别为95.3%、85.6%、96.91%。
Abstract:Oxygen pressure zinc leaching is a new hydrometallurgy process. 40% high-sulfur slag will be produced during the process. Due to uneven particle size and high viscosity of high sulfur slag, research on process mineralogy is not in-depth, which makes it difficult to treat and utilize high sulfur slag. Taking high-sulfur slag, sulfur concentrate and sulfur tailings from a zinc smelter in Inner Mongolia as research object, its process mineralogical characteristics, comprehensive recycling of valuable metals such as lead, zinc, copper and silver were studied. XRF, polarized light microscope, SEM-EDS, laser particle size analyzer and MLA mineral dissociation analyzer were used to explore elements, mineral composition, particle size and continuous growth of high-sulfur slag, sulfur concentrate and sulfur tailings. Sulfur recovery in flotation of high sulfur slag is 84.5%, recovery of Pb, Zn and Ag is 95.3%, 85.6% and 96.91%, respectively, after sulfur tailings put into lead smelting system of Ausmelt oxygen-rich top-blown furnace.
