Abstract: A basic oxygen furnace slag treatment method includes the steps of mixing basic oxygen furnace slag with an active aqueous solution and then keeping the mixture thus obtained under an enclosed environment for reaction and then employing a solid-liquid separation procedure to separate solid phase from liquid phase. Since basic oxygen furnace slag has strong alkaline, the method of the invention overcomes the problem that directly discharging basic oxygen furnace slag will cause environmental pollutions. The basic oxygen furnace slag treatment method avoids a secondary pollution, and can turn waste into treasure, bringing a number of economic benefits.
