摘要
通过盈亏平衡分析,确定宜春钽铌矿盈亏平衡品位,提出黑斑矿的处理方案。依据矿山管理目标所确定的生产技术经济指标及价格预测推算,2002年开采的Ta_2O_5盈亏平衡品位为0.0134％,送往选厂还是送往废石堆场的Ta_2O_5盈亏平衡品位为0.0120％。在现有的经济技术条件下,黑斑矿应确定为次边际经济资源,暂无开采利用价值。
The breakeven grade of tantalum for Yichun Tantalum-niobium Mine is determined by the analysis of the profit and loss, and the strategy on the black-spot ore exploration is proposed. The breakeven grade of tantalum of Yichun Tantalum-niobium Mine in 2002 is 0.0134%, and for processing in case of necessary mining is 0.0120% . The black-spot ore is sub-marginal economical resources and inadvisable to utilize at the present technical and economic conditions.
