Embodiment 1
[0031] The present invention takes the antimony-gold concentrate of a certain antimony smelter in Lengshuijiang, Hunan as the research object, and distributes 37.8kg of antimony-gold concentrate (Sb24.47%; Au 71.10g / t) on the steel strip with a width of 280mm and a thickness of 40mm and control the temperature of the furnace at 1050°C. After the temperature is stabilized, the steel strip is opened at a running speed of 2m / h for 2h, and finally 16.7kg of volatile slag is obtained. The slag contains 0.81% antimony, 157.80g / t gold, and The recovery rate was 98.54%, and the loss rate of gold was only 1.95%.
Embodiment 2
[0033] The present invention takes the antimony-gold concentrate of a certain antimony smelter in Huaihua, Hunan as the research object, and distributes 37.8kg of antimony-gold concentrate (Sb41.53%; Au 32.50g / t) on the steel strip with a width of 280mm and a thickness of 40mm , and control the temperature of the furnace at 950°C. After the temperature is stabilized, the steel strip is opened at a running speed of 2m / h for 3h, and finally 20.62kg of volatile slag is obtained. The slag contains 1.02% antimony and 58.96g / t gold, and the recovery of antimony The rate was 98.66%, and the loss rate of gold was 1.03%.
