The zinc balance of 2 500 m~3 BF ironmaking and corresponding sintering process is studied in Xinyu Steel. Results show that the amount of zinc into the blast furnace of 1. 055 kg/t,is mainly composed of sinter and pellet among then,the sinter carries 84% of the total amount of zinc. Zinc blast furnace is mainly discharged through bag dust（ accounting for 89% of the total discharge）.IN 1. 162 kg/t zinc is carried in sintering process,mainly comes from blending materials,internal cold back to mine and dust（ accounting for 97. 47% of the total）,discharged by the sinter and recovery of zinc ore（ accounting for 95. 92% of the total discharge）. According to the actual production situation in Xinyu Steel,the measures to reduce the amount of zinc and increase the amount of zinc are put forward.
