矿产取样贯穿于普查找矿、矿床评价和勘探工作的始终.从经济地质角度来看,由普查找矿到矿床勘探,就是一个对矿床的取样过程.一般说,样品的规格和重量越大,对矿体中物质组分的了解也越充分.然而加大样品规格又将提高勘探成本,延长勘探周期.因此,确定经济合理的样品规格,就成了一个重要的地质经济问题. 本文选择了铜、铅、锌、钨、锡、锑、钼、金、铁、铝(粘土)11个矿种的16个典型矿床,
Mineral sampling runs through the census prospecting, deposit evaluation and exploration work has always been from the economic geology point of view, from census prospecting to deposit exploration, is a deposit of the sampling process.Generally speaking, the larger the size and weight of the sample, The more fully understanding of the material composition in the ore body.However, increasing the sample size will increase the exploration cost and prolong the exploration cycle.Therefore, it is an important geo-economic issue to determine the economic and reasonable sample size.This paper chooses Sixteen typical deposits of 11 minerals including copper, lead, zinc, tungsten, tin, antimony, molybdenum, gold, iron and aluminum (clay)
