从难处理矿石和精矿中回收金可采用焙烧和浸出法的多种方法来实现。悉罗熔炼装置是从这些物料回收金的新型熔炼方法。实验室研究了悉罗熔炼装置从含金17.5克/吨矿石和含金22克/吨精矿中回收黄金、伴生育价金属和大量的金属铜。铜、铁、铅和冰铜作为金的收集相。矿石熔炼过程中金的回收率为80～90%而精矿熔炼过程中金的回收率可达98～99%。 Recovering gold from refractory ores and concentrates can be accomplished in a number of ways, including roasting and leaching processes. The smelting plant is a new smelting method that recovers gold from these materials. The laboratory studied the distillation of Gold from 17.5 g / t ore and 22 g / t gold concentrate with associated fertility metals and copious amounts of metallic copper. Copper, iron, lead and matte as the collection phase of gold. The recovery rate of gold in ore smelting process is 80-90% while the gold recovery rate in concentrate smelting process can reach 98-99%.
