The comparative advantages of slurry electrolysis of antimony over traditional processes

（1）Simplified process

Traditional antimony extraction processes usually require multiple complex processes, such as roasting, leaching, purification, and electrolysis, while the antimony slurry electrolysis process integrates ore leaching, solid-liquid separation, metal electrolysis, and solution circulation into a continuous production process, reducing the number of intermediate links and material transfer times, shortening the process flow, and improving production efficiency.

（2）Improved environmental performance

Traditional processes will produce a large amount of sulfur-containing and dust-containing waste gas during roasting and other links, causing serious pollution to the environment. The antimony slurry electrolysis process is carried out in a relatively closed system, with less waste gas generated, and the small amount of acidic waste gas generated is less difficult to treat. At the same time, the electrolyte of this process is recycled, and there is basically no need to add other reagents except hydrochloric acid, which reduces the amount of wastewater and waste slag generated, and can achieve no wastewater discharge in the production and operation of the slurry electrolysis workshop, reducing the negative impact on the environment.

In summary, in terms of process principles, key technologies and comparison with traditional processes, antimony slurry electrolysis technology has technical advantages such as short process, high metal recovery rate and low energy consumption. It has a high degree of technical feasibility and provides an advanced, efficient and environmentally friendly technical path for the extraction of antimony.
