Example Embodiment
[0028] Example 3: A high-lead antimony slag type used in anode slime smelting process. The specific formula is a high-lead antimony slag type with low silicon, low calcium and low sodium, and the composition of each raw material according to the mass ratio is: SiO 2 Is 17 tons, FeO is 7 tons, Na 2 O is 0~6%, CaO is 1 ton, PbO is 33 tons, Sb 2 O 3 Is 42 tons, which is based on SiO 2 , FeO, CaO, PbO and Sb 2 O 3 The mass ratio of the five oxides is 100 tons, the ratio of the five oxides is 17:7:1:33:42; PbO:SiO 2 =1.94; namely PbO and SiO 2The ratio is controlled between 1.50~6.0. Slag melting point 900~1250℃, slag density: 3.9~4.6g / cm 3 . Slag melting point 900~1250℃, slag density: 3.9~4.6g / cm 3 .
