More than 60% of the world's boron is from Turkey and China, with smaller amounts coming from Morocco. 2. China. It is the largest producer of boron in mining. Because China mines and processes more than 44 million metric tonnes annually. In 2016, China produced about $12 billion worth of minerals.

Additionally, water leaching characteristics of the residues and boron kinetics were analyzed. The results demonstrated that boron leaching efficiency reached 93.71% from the reduced ludwigite ore under specific conditions: leaching temperature of 180 °C, leaching time of 6 h, liquid-to-solid ratio of 8:1, and feed particle size of 52.31 μm ...
