江西有色金属矿床伴生组份的综合评价问题

Comprehensive Evaluation of the Rare-Dispersive Constituents Associated with the Nonferrous Ore Deposits in Jiangxi

有色金属矿床通常都含有伴生的稀散元素.地质勘探中,仅以矿石含某种稀散元素的平均品位达到某一下限要求为依据,进行综合评价和计算储量是不恰当的.应该加强矿石物质组成和选矿试验的研究,探讨稀散组份在选矿合格产品中的富集程度来确定综合评价和计算表内储量的准则.

Generally nonferrous ore deposits contain different rare-dispersive constituents in more or lessquantity. It is inappropriate to make a comprehensive evaluation or ore reserves calculation for a deposit merely based upon the average content (reaching a certain lower limit) of one of the rare-dissersive constituent in the ores. Ore mineral composition studies and ore dre sing tests should be strengthened. An investigation of the enrichment factor of the rare (dispersive) constituents in the qualified products from beneficiation to formulate some criteria for comprehensive evaluation of oredeposits and the calculation of utilizable ore reserve is necessary.
