Embodiment Construction
[0014] According to the monthly output of 1,000 tons of stone materials, three plastic silos are used, and each silo is loaded with more than 15 tons of materials, covering an area of about 60 square meters, and can be equipped with a shed. Put the crushed quartz stone or feldspar and other crushed stones in the plastic silo and close the silo, heat the hydrochloric acid, hydrofluoric acid or sulfuric acid solution with a concentration of more than 25% by mass to 50°C-110°C, and The heated acid solution is pumped into the closed silo through the pipeline, and the high-temperature acid gas is generated by the mist maker, so that all the crushed stones are placed in the high-temperature acid solution and acid gas, and the high-temperature acid gas and acid solution are in the closed material React with the ore skin and impurities in the silo, and use high-temperature acid gas to accelerate the reaction process in the closed silo. After about 8 hours of reaction, the acid gas a...
