Abstract
Metallurgical slag of laterite nickel ore contains valuable Al and Si that can be recycled by alkali roasting and water leaching process. The leaching solution was further treated to make zeolite materials as a high-value-added by-product. In this work, the contents of silicon and aluminum in the filtered liquor after water leaching was determined by ICP, and the solid residue was characterized by the laser particle-size distribution analyzer and SEM. The results showed that the contents of Al and Si in the filtered liquor increased by 44 and 65%, respectively, by using ultrasound ; and the leaching residue was even more fine and uniform, and its grain size was reduced from 100 to 10 μm. This demonstrates that ultrasound can enhance the leaching efficiency of Al and Si for better recycling of the valuable metals and improving the quality of zeolite materials.
