Abstract. A novel process for boron enrichment and extraction from ludwigite based on iron nugget technology was proposed. The key steps of this novel process, which include boron and iron separation, crystallization of boronrich slag, and elucidation of the boron extraction behavior of boronrich slag by acid leaching, were performed at the laboratory.
