Abstract Red mud is the solid waste residue generated during alumina production from bauxite， which contains considerable amount of alumina， ferric oxide and other valuable metals. In order to recovery alumina and iron from red mud， the process of pig iron produced by direct reduction-smelting of carbon-containing red mud pellets， and alumina leaching from self-disintegrating slag was developed. The effects of different process parameters on extraction of iron and alumina from red mud were researched. The optimum reaction parameters were obtained as the following： the ratio of carbon to oxygen is 1.8， the time of direct reduction at 1 250 ℃ is 60 min， the time of smelting at 1 500 ℃ is 20 min， slag cooling rate must be less than 20 ℃/min， the ratio of calcium oxide to alumina is 1.6. With these optimum parameters， the phosphorus and sulfur content in the pig iron were 0.047% and 0.017% respectively， the ferrous oxide content in the slag was 1.26%， the slag can disintegrate completely， and the alumina leaching ratio can reach 86.65%.
