Abstract

The invention provides an acid leaching device for silicon ore purification and relates to the production field of silicon ore purification. According to the acid leaching device, an outer sleeve for medium access is arranged outside an acid leaching cylinder body, so that the leaching of hot acid is facilitated and the processing time is shortened; a spiral stirring shaft provided has an excellent stirring effect during acid leaching and improves the acid leaching effect; an acid gas filter layer arranged on an acid gas outlet performs gasification treatment on the acid gas generated during leaching of hot acid so as to reduce harm of the acid gas to human and the environment.

Description

[0001] technical field [0002] The invention relates to the production field of silicon ore purification, in particular to an acid leaching device for silicon ore purification. Background technique [0003] With the advancement of science and technology, high-tech industries such as optical power supply, electronics industry, optical communication, SiO2 thin film materials, large-scale and ultra-large-scale integrated circuits, lasers, aerospace, military industry and other high-tech industries are developing rapidly, and the demand for high-grade quartz raw materials is very high. big. However, due to the high quality requirements of these special quartz raw materials, the required content is usually greater than 99.9%, or even 99.99%, while the allowable impurity content is very low. Only high-grade natural primary and secondary crystals can meet the requirements. Natural crystal resources are becoming increasingly depleted, especially high-grade natural crystal resou...
