Gold Electrolysis Refining Comprehensive Recovery Technology Research And Application

Know about the loss of gold of each link way and attrition rate through casting process research of cicc loss situation of manufacturing of electrolyte, anode plate casting, electrolysis. lay a foundation of reducing the wastage of the gold, improve the establishment of comprehensive recovery plan..Proposes a 3 system joint dust collecting project, such as: Dust from cooling subsidence, micro small bag dust collecting, the end of the water bath dust. Applicated in the gold smelting workshop and application effect shows that the syste m can make the gold dust collection efficiency of 97% or more, the comprehensive recovery of gold are not in front of the dust collecting 99.81% to 99.95%, so the obvious economic benefits. The comprehensive recovery of gold also rose to 99.95% from 99.81% do not collect dust. That alone, a direct economic benefit of 1.19 million yuan.In this paper, the electrolytic tail liquid technology is to use sodium hydroxide after neutralization with sodium sulfide precipitation these valuable elements. The process in the electrolytic workshop for practical application and the application effect shows that the system can make the reduction of the tail liquid electrolyte precious metal elements are fully recycled.This study also has developed a new technology of anod e slime treatment. The process is basically realized completely separate, gold and silver silver losses to a minimum, the purity of gold increased significantly,thus it can reach 99.8% and it make its can be directly cast anode electrolysis,and fully meet the requirements of gold electrolysis. It increases the efficiency and reduces the backlog of cicc process; Almost all the silver has been recoverd from the anode slime, and the content also increased to more than 99%. Nearly 1 years, the use of the techno logy recycling silver 94.31877 kg, the direct economic benefit of 700000 yuan.The above process has improved the efficiency and reduced the process of cicc backlog. Improve the management benefit of enterprise.
