甘肃敦煌市新泉北钒多金属矿床概略经济评价

新泉北钒多金属矿是近年来在方山口-七角井金、钨、锰、钒、磷、铀成矿带黑色岩系中发现的5个大中型钒矿之一。本文整理近年来钒矿资源的市场信息,参照邻区同类矿山选矿工艺、开采经济技术指标,结合新泉北钒多金属矿资源储量、开采技术条件、矿山建设条件、钒产品市场价格等,进行概略经济评价。结果表明该矿床具有投资效益好、内部收益率高、利润可观、投资回收期短、服务年限长的特点,开发前景好。本文对该地区同类矿床下一步勘查、开发具有参考意义。

Economic evaluation of the North Xingquan vanacdium polymetallic deposit in Dunhuang,Gansu Province

Xinquanbei vanadium polymetallic deposit is one of many large and medium-sized vanadium deposits found in the black rock series of the gold, tungsten, manganese, vanadium, phosphorus and uranium metallogenic beit in Fangshankou in recent years. In this paper, the market information of vanadium ore resources in recent years is sorted out, and the economic ang technical indexes of ore dressing process and mining of similar mines in the adjacent area are referred to. The economic evaluation is made on the basis of the reserves of vanadium polymetallic ore reserves, mining technical conditions, mine consteuction conditions, market price of vanadium products, etc. The results show that the deposit has the characteristics of good investment benefit, high internal rate of return, considerable profit, short paybank period and long service life, and good development prospect. This paper has guiding and demonstration significance for the next exploration and development of similar deposits in this area.
