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 boron-rich slag, and elucidation of the boron extraction be- havior of boron-rich slag by acid leaching, were performed at the laboratory. The results indicated that 95.7% of the total boron could be en- riched into the slag phase, thereby forming a boron-rich slag during the iron and slag melting separation process. Suanite and kotoite were observed to be the boron-containing crystalline phases, and the boron extraction properties of the boron-rich slag depended on the amounts and grain sizes of these minerals. When the boron-rich slag was slowly cooled to 1100℃, the slag crystallized well and the efficiency of ex- traction of boron (EEB) of the slag was the highest observed in the present study. The boron extraction property of the slow-cooled bo- ron-rich slag obtained in this study was much better than that of szaibelyite ore under the conditions of 80% of theoretical sulfuric acid amount, leaching time of 30 min, leaching temperature of 40℃ ,and liquid-to-solid ratio of 8 mL/g.
