摘要:
Red mud is a strong alkaline waste from the Bayer process for Al production, which is known as a promising polymetallic secondary resource. The stockpiling and landfill disposal of red mud have produced environmental pollution and resource waste. A novel, promising, environmentally friendly technology for simultaneous extraction of valuable metals from red mud was proposed by ammonium sulfate calcination at temperatures of 250-400? and water leaching. The phase change in the calcination process and various parameters such as the amount of ammonium sulfate, calcination temperature, calcination ...
