摘要
官地银金矿床的原生矿石和氧化矿石在矿石颜色、矿物粒度、矿物组合和银金赋存状态均有明显差异。因此，氧化矿石在采矿和选矿上只能采取单采单选的方法。通过官地银金矿床银的物相、铅锌物相和铁锰物相的试验研究，来划分氧化带的范围和确定其埋深。官地银金矿床是应用物相锰来划分氧化带，即锰氧化率＝Ｍｎ４＋／ＴＭｎ×１００％，当锰氧化率≥２５％时划为氧化矿，＜２５％时划为原生矿，这一试验研究成果为官地银金矿床选择采选方案提供科学试验依据。
The primary ores of Guandi Ag Au deposit are obviously different from the oxidation ores in ore colors,mineral grain sizes and association as well as in the existing status of silver and gold,Therefore,the oxidation ores have to be separately mined and processed.Through the experimental study of the matter phases for silver,lead zinc,and iron manganese in Guandi Ag Au deposit,the scope of the oxidation zone is outlined and the depth is determined.The classification of the oxidation zone is made by using Mn matter phases.i.e.the Mn oxidation ratio defined by Mn 4+ /TMn×100%.The Mn oxidation ratio ≥25% define oxidation ores,and the Mn oxidation ratio <25% will define the primary ores.The experimental results in this study may be used as a scientific reference for the selection of mining and processing schemes in Guandi Silves Gold Deposit
