Beneficiability Study of the Blast Furance Dust from Tangshan Iron and Steel Company

摘要

Through the analysis and study the properties, characteristics and present conditions of the flue slime of blast furnace dust, a suggestion was made of recovering carbon and iron concentrate from the blast furnace dust using a beneficiation technology consisting of gravity separation-flotation. The laboratory test results indicated that it can obtain the iron/carbon concentrate with a grade of iron 53.41%, carbon 65.21% at a recovery rate of iron 51.33%, carbon 69.29%. This mineral processing technology achieved good technical and economical results, reaching the expected effect. The technology can be applied in production and popularized.
