该矿石属于含金银的复合矿石,除含金银外尚有铜,硫等有益组分,对这些有益组分进行综合回收的研究具有重要意义。一、矿石性质该矿石中金属矿物主要为黄铁矿,其次为黄铜矿、方铅矿,铜蓝和辉铜矿等。金银矿物主要为银金矿、金银矿、辉银矿和少量自然金、碲金矿。金银嵌布粒度一般在0.01—0.02毫米。金银矿物与硫化矿紧密共生。脉石矿物主要为石英,其次为微斜长石、钠长石、奥长石、黑云母等。矿石的化学组份见表1,铜铅的物相分析见表2,金的物相分析见表3。
The ore belongs to the composite ore containing gold and silver. Except for the gold and silver, there are still some beneficial components such as copper and sulfur. The research on the comprehensive recovery of these beneficial components is of great significance. First, the nature of the ore The ore minerals mainly pyrite, followed by chalcopyrite, galena, copper blue and chalcocite. Gold and silver minerals are mainly silver gold, gold and silver ore, silver mine and a small amount of natural gold, tellurium gold. Gold and silver cloth size is generally 0.01-0.02 mm. Gold and silver minerals and sulfide ore closely together. The gangue minerals are mainly quartz, followed by plagioclase, albite, opalite and biotite. Ore chemical composition shown in Table 1, copper and lead phase analysis in Table 2, the phase analysis of gold in Table 3.
