摘　　要：赤铁矿烧结主要是还原 再氧化反应过程 ,与磁铁矿烧结相比 ,其能源消耗较高。用浮选法选别后的赤铁精矿具有细、粘等特点 ,烧结过程中表现为混匀难、造球难、烧结难、能耗高。本文介绍了鞍钢矿业集团东烧厂采用这种浮选赤铁细精矿烧结的节能降耗经验和措施。The energy consumption of hematite concentrate sintering is higher than magnetic concentrate sintering because the main reactions are reduction/re-oxidation reactions during hematite sintering. As the flotation hematite concentrates possess the properties of fine grain and viscosity, so it was rather difficult to mix, to blend and to sinter. The experience and measure about flotation hematite concentrate sintering were presented in this paper.
