Abstract

An electrolytic manganese slag glass-ceramic and a preparation method thereof relate to the preparation of glass-ceramics by using industrial waste and the method thereof. The raw material of electrolytic manganese slag glass-ceramics of the present invention is electrolytic manganese slag, calcium carbonate, quartz sand and magnesium carbonate; Chemical treatment, annealing and processing into finished products. The invention has the characteristics of few raw material components (only 4 types), large amount of electrolytic manganese slag (up to 75-99.7%), simple preparation method, low production energy consumption, and environmental protection. The electrolytic manganese slag glass-ceramic of the present invention prepared by the method of the present invention can be widely used as a building decoration material.

Description

technical field [0001] The invention belongs to the technical field of glass-ceramics, and in particular relates to the preparation of glass-ceramics by utilizing industrial waste and a method thereof. Background technique [0002] my country is the world's most important producer of manganese metal, with an annual manganese output of more than 90% of the world's total output, and most of its products are obtained through sulfuric acid rhodochrosite (the main active ingredient is MnCO 3 ) is achieved by electrolysis after obtaining the electrolyte manganese sulfate. Due to the fact that MnCO in my country's manganese ore 3 The content is only 20%, and other mineral components in the ore are discharged in the form of electrolytic manganese slag during the compound reaction process. Generally speaking, about 7 tons of electrolytic manganese slag are produced on average for every ton of electrolytic metal manganese produced. Due to the lack of effective means of utilization, ...
