杨家堡下寒武统黑色岩系中,含钒的腐泥煤和次腐泥煤(一般称为含钒石煤)是以钒为主并伴有多种金属元素的大型海相沉积矿床。层位稳定、分布广泛、规模巨大,是一种新型的矿产资源——黑色页岩型多金属矿床。杨家堡含钒石煤中V_2O_5含量达0.7—4.63％,一般品位为0.8—1.0％,完全符合作为独立钒矿床开采的要求。对杨家堡含钒石煤物质成分和钒的赋存状态的研究,是为杨家堡石煤提钒工艺流程的确定提供必要的数据和理论依据,并为黑色页岩型多金属矿床成因理论的研究提供基础资料。
In the Lower Cambrian black rock series of Yangjiabu, the vanadium-bearing sapropelite and sub-sago peat (commonly referred to as vanadium-bearing stone coal) are large marine sedimentary deposits mainly composed of vanadium with a variety of metallic elements . Stable, widely distributed, large-scale, is a new type of mineral resources - black shale-type polymetallic deposits. The content of V_2O_5 in Yangjiapu vanadium-containing stone coal is 0.7-4.63%, and the general grade is 0.8-1.0%, which fully meets the requirement of mining as an independent vanadium deposit. The research on the composition of vanadium-containing stone coal and the occurrence of vanadium in Yangjiabao is to provide the necessary data and theoretical basis for the determination of the process of vanadium extraction from Yangjiapu stannum, and provide the theoretical basis for the formation of black shale polymetallic deposits Theoretical research provides the basic information.
