一、引言杨家堡钒矿位于湖北省的西北部,是一个贮量较大,品位较高,层位稳定,开采方便的含钒石煤矿床,是我国钒矿资源中重要的一种。湖北省地质局实验室、大冶有色金属公司矿冶研究所等单位先后对矿石的物质成分、技术加工作了大量的实验研究工作,取得了较好的指标,为建成中间试验工厂提供了可靠的设计依据。但 V_2O_5的回收率不高,仅48.3%,精矿中含有大量的杂质。本
I. Introduction Yangjiapu vanadium ore is located in the northwestern part of Hubei Province. It is a vanadium-bearing stone coal deposit with large reserves, high grade, stable horizon and convenient mining. It is an important type of vanadium ore resources in China. Hubei Provincial Bureau of Geology Laboratory, Daye Nonferrous Metal Mining and Metallurgical Institute and other units of the ore has a lot of experimental work on the material composition, technology and processing, and achieved good indicators for the establishment of an intermediate pilot plant to provide a reliable The design basis. However, the recovery rate of V2O5 is not high, only 48.3%, the concentrate contains a lot of impurities. this
