岩金矿山损失率与贫化率计算方法探讨

Investigation on calculating methods of both loss and dilution rates in rocky gold mine

本文用公式的推导说明岩金矿山通常采用的间接法计算损失率、贫化率公式的局限性，并指出了总贫化率计算公式的错误所在，提出了计算二率的科学方法。

According to derivation of equation, this paper points out the limitations of the formulae to calculate both loss and dilution rates in rocky gold mines which are arised from indirect method and employed usually. It also points out where the mistakes lie in the formula to calculate toeal dilution rate and puts forward a scientific method to calculate both of them.
