摘要
运用盈亏平衡品位方法,探讨了宜春钽铌矿采选黑斑矿是否经济合理,并进行采选决策;低品位黑斑矿品位低于目前的盈亏平衡品位,在现有技术经济条件下采选黑斑矿企业要亏损,黑斑矿为次边际经济资源,暂无开采利用价值。
The method of breskeven grades is used to decide if the black-spot ores are economic or not in Yichun Ta ＆ Nb Mine and make decision of mining and dressing. If the grades of black-spot ores are lower than present balance grades, the mines which are mining and dressing the ores will suffer loss. The result is that the blackspot ores are sub-marginal economical resources and are not worth exploring.
