对于内生金属矿床,特别是组份分布不均匀或极不均匀的金属矿床,查明有无特高品位存在,是一个重要问题,因为这涉及到高品位样品值算不算特高品位因而是否需要进行处理的问题。以往,内生金属矿床中有无特高品位,通常都是利用经验数字(即高品位样品的品位值 For endogenous metal deposits, especially metal deposits with unevenly distributed or highly heterogeneous compositions, identifying the presence or absence of extra-high grade is an important issue as it relates to the fact that high-grade sample values ​​are not considered to be extraordinarily high grade Need to deal with the problem. In the past, whether endogenous metal deposits in the ultra-high grade, usually are the use of empirical figures (ie, high-grade sample grade value
