This instructive technical document specifies a method for the determination of antimony content in lead concentrates using the cerium sulfate Titrimetric method, which is suitable for the determination of antimony content in the range of 0.80% to 12.00%. After the sample is analyzed in sulfuric acid and nitric acid medium, the antimony is reduced by carbonized filter paper, and then the iron ions are masked with phosphoric acid, and titrated with cerium sulfate standard solution to the end point. The document details the preparation of reagents, experimental procedures and data processing, providing an effective method for the analysis of antimony content in lead concentrates.
