ABSTRACT

Our study investigates the condensation mechanism of vapors containing arsenic, with a particular focus on the conditions required for the creation of melted and dispersed sulfide condensate that have practical implications in technological processes. Our findings indicate that at vapor jet efflux under low pressure, ultrafine particles generates in the condensation space at first. Then they are precipitated on the cooled walls of the condenser. We explored the transition of arsenic sulfide vapor into the liquid phase and noted a simultaneous occurrence of the crystalline and liquid condensates. Our findings will provide valuable guidance for designing and operating industrial processes for gold-bearing concentrate dearsenation in a vacuum, with the potential for improved safety and efficiency.

摘要

我们的研究研究了含砷蒸气的冷凝机理，特别关注产生熔融和分散的硫化物冷凝物所需的条件，这在技术过程中具有实际意义。我们的研究结果表明，在低压下蒸气射流流出时，超细颗粒首先在冷凝空间中产生。然后它们沉淀在冷凝器的冷却壁上。我们探索了硫化砷蒸气向液相的转变，并注意到晶体和液体冷凝物的同时出现。我们的研究结果将为真空含金精矿脱砷工业流程的设计和操作提供有价值的指导，并有可能提高安全性和效率。
