The high-iron Bayer red mudHigh-iron Bayer red mud , which contains 30–50% ironIron , is regarded as low-grade ironIron ore. With the global scarcity of ironIron supply worldwide, how to effectively utilize the ironIron in high-ironIron red mudRed mud has attracted more and more attention in recent decades. In this paper, the technology to recoveryRecovery of ironIron from high-ironIron red mudRed mud was developed with smelting reductionSmelting reduction followed by rapid cooling to separate the metal from slag. The effects of various experiment parameters such as temperature, basicity and reductionReduction time on iron recoveryIron recovery from red mudRed mud was studied in detail. The results showed that the separation between metal and slag was complete. The content of ironIron in metal and iron recoveryIron recovery ratio were 94.06 and 80.16% with basicity of 0.9 smelting at 1600 °C for 30 min. The optimum experiment result were of great significance to achieve large-scale, high-value utilizationUtilization of red mudRed mud .
