取样的目的在于确定矿石中有益組分及有害杂質的含量,从而作为矿体圈定、矿石品級划分及儲量計算的根据。因此取样的正确与否,直接影响到矿床評价及矿物利用的正确性。黑鎢矿在矿体中的分布一般可以分为如下几种:①,矿物晶体的大小相近似,分佈較爲均勻②;矿物晶体大小不一,分佈很不均匀,有时呈分段富集,在矿脈上下盤圍岩中,亦往往含矿;③矿物晶体分佈极不
The purpose of sampling is to determine the beneficiation components and harmful impurities in the ore content, thus as ore delineation, ore grade division and reserves calculation basis. Therefore, whether the sampling is correct or not will directly affect the evaluation of the deposit and the correctness of mineral utilization. Wolframite distribution in the ore body can be generally divided into the following categories: ①, the size of the mineral crystals are similar, the distribution is more uniform ②; mineral crystals vary in size, distribution is uneven, and sometimes segmented enrichment, In the veins around the rock, also often contains ore; ③ mineral crystal distribution is extremely
