| 摘 要： | 随着煤炭综合开发利用的增加,急需确定煤中大部分伴生元素综合回收利用的品位和边界品位,以便在煤炭勘探阶段采取综合评价措施,降低勘探成本。参照《矿产工业要求参考手册》中各类元素的工业品位和边界品位,世界煤中微量元素平均含量,以及根据国家各项技术经济政策和市场要求,综合考虑给出原煤中部分伴生微量元素综合回收利用指标,建议锂、铀、钍和稀土的综合回收利用指标分别应该为120,40,150和300 mg/kg。

Minimum mining grade of the selected trace elements in Chinese coal |

| Abstract: | As increase of coal comprehensive utilization，it is urgent to establish comprehensive utilization grades of some trace metal elements in coals in order to taking comprehensive evaluation measures in coal exploration stages and to decrease the exploration cost.High concentrations of trace elements in coal seams were reported by several papers in recent years.In this paper，the comprehensive utilization grades of Li，U，Th and REE were suggested by compared their enrichments in coal with the Geology and Ore Deposit Standard Specifications in rocks for Rare Metal Mineral Exploration of the People’s Republic of China(DZ/T 0203—2002)，and also compared with the minimum mining grade for Ga and Ge in coals.The author suggests that the minimum mining grades of Li，U，Th and REE should be 120，40，150 and 300 mg/kg，respectively. |
