摘要
采用当次放出矿石收支平衡方法,利用鸡冠山铁矿2002年经济指标,从车间和矿山的角度,分别计算了鸡冠山铁矿经济合理的放矿截止品位。据此计算了截止放矿时的矿岩比,为放矿提供了科学依据。
From the viewpoint of ore treating processes and viewpoint of mining, the economically reasonable breakeven grade of iron ore is calculated respectively using Income- Expenditure Balance Method of mined out ore and referencing the economic indexes of 2002. On this basis, the ore/rock ratio at the time of stopping ore withdrawal is calculated proving a reliable basis for ore withdrawal.
