We employ a highly controlled, state-of-the-art electrolysis process to transform raw antimony ore into 99% pure ingots. This method ensures superior quality control and minimizes environmental impact compared to traditional pyrometallurgical techniques.
Our process is a symphony of precision chemistry and advanced engineering, guaranteeing a final product of unmatched purity.
Raw stibnite (antimony sulfide) is crushed and milled into a fine powder to maximize surface area for subsequent chemical leaching operations.
The powdered ore is dissolved in an alkaline sodium sulfide solution. This highly selective leaching process separates the antimony from gangue minerals and common impurities.
The antimony-rich solution is transferred to our high-tech electrolytic cells. Under carefully monitored voltage and direct current, pure antimony metal deposits onto the cathode plates.
The deposited metal is mechanically stripped from the cathodes, thoroughly washed to remove residual electrolyte, and melted in an induction furnace under controlled atmospheric conditions.
The molten 99% pure antimony is cast into precise ingots. Each batch undergoes rigorous laboratory analysis using spectroscopy to formally certify its purity before shipping.
