Manganese slag treatment method, application thereof and magnesium oxide board
The invention belongs to the technical field of industrial waste residue treatment, and provides a manganese residue treatment method and application thereof and a glass magnesium planes.The manganese residue treatment method comprises the steps that a mixed solution containing manganese residues, magnesium salt, magnesium oxide and water is stirred, the magnesium oxide reacts to remove ammonium sulfate in the manganese residues, and a soluble manganese source contained in the manganese residues is converted into manganese oxide; the mixed gel comprises magnesium salt, magnesium oxide, magnesium sulfate and a manganese-containing compound, and the manganese-containing compound comprises manganese oxide. The magnesium oxide and the magnesium salt are utilized to form a gel system, the magnesium oxide can convert ammonium sulfate in the manganese slag into magnesium sulfate and ammonia gas, and the magnesium sulfate can be used as the magnesium salt; and a gel environment formed by magnesium oxide and magnesium salt can react and convert a soluble manganese source in the manganese slag into manganese oxide, so that harmless treatment of the manganese slag is realized. In addition, the formed mixed gel can be used as a preparation raw material of the magnesium oxide board, and the prepared magnesium oxide board meets environmental protection requirements and quality requirements.
本申请属于工业废渣处理技术领域，提供了一种锰渣处理方法及其应用和玻镁板材，锰渣处理方法包括：将含有锰渣、镁盐、氧化镁和水的混合液进行搅拌，氧化镁反应去除锰渣中的硫酸铵，并将锰渣中含有的可溶性锰源转化为氧化锰；得到包括镁盐、氧化镁、硫酸镁以及含锰化合物的混合凝胶，含锰化合物包括氧化锰。本申请利用氧化镁和镁盐形成的凝胶体系，其中氧化镁能够将锰渣中的硫酸铵转化为硫酸镁和氨气，硫酸镁能够作为镁盐进行使用；而且氧化镁与镁盐形成的凝胶环境能够将锰渣中的可溶性锰源反应转化为氧化锰，实现锰渣的无害化处理。此外，形成的混合凝胶能够作为玻镁板材的制备原料，且制备的玻镁板材满足环保要求和质量要求。
