利用大洋锰结核还原氨浸渣为原料通过水热法合成了纳米态钾锰矿,并分析了反应pH值对合成产物物相、晶体形态的影响。实验结果表明,合成反应较佳pH值为5～7,反应体系中存在K+、SO42-对合成纳米态钾锰矿十分有利。该方法降低了钾锰矿合成成本,为钾锰矿商业化生产提供了思路,同时为大洋锰结核氨浸渣的资源化利用和清洁生产开辟了新的途径。
The nanocrystalline potassium manganese ore was synthesized by hydrothermal method using the oceanic manganese nodule reduction ammonia leaching residue as raw material, and the influence of reaction pH value on the phase and crystal morphology of the synthesized product was analyzed. The experimental results show that the optimum pH value of the synthesis reaction is 5 ~ 7, and the presence of K + and SO42- in the reaction system is very favorable for the synthesis of CaMnomorphism. The method reduces the cost of potash manganese synthesis, provides a train of thought for commercial production of potash manganese ore, and opens up new avenues for the resource utilization and clean production of ocean manganese nodule ammonia leaching residue.
