As a core member of non-metallic minerals, silica has become a key raw material for promoting the development of industries such as semiconductors, photovoltaics, and metallurgy due to its unique physical and chemical properties.However, due to the differences in associated minerals of silica in different distribution regions, the processing of silica requires a process of "impurity removal".

一、Introduction to types of silica

      As we all known,The main component of silica is silicon dioxide.According to differences in purity and physical form, silica can be divided into the following categories:One is metallurgical grade silica.The second is glass grade silica.The third is chemical grade silica.The fourth is refractory grade silica.Number five is photovoltaic grade silica.Six is fiber grade silica.

二、The opportunities brought by AI sorting technology to silica sorting

     The impurity sorting of silica directly determines the added value of its end products. In the past, traditional color sorting machines were unable to cover all aspects of silica with different accompanying organisms，but now,the AI sorting machine from Mingde Optoelectronics has already arrived.

      For simple silica,such as Quartzite ore,it has Iron that containing oxides,this is clearly different from white silica ore, so a color sorter can be used to deal with it.However,for complex cilica mixed with similar color wasted ore,it need AI sorting tech.For example, AI sorting machines can effectively separate feldspar and mica from silica.

     The artificial intelligence sorting machine recognizes multi-dimensional surface features (color, texture, shape) and combines deep learning models to distinguish between mica and feldspar. For example, mica flakes can be accurately sorted by color and shape characteristics, while feldspar can be identified by differences in texture, luster, and texture. Pre treatment of waste can reduce grinding energy consumption and the costs of electric selection, magnetic separation, and flotation.

三、The significanse of AI sorting tech for silica industry

      Mingde Optoelectronics' technology not only solves the efficiency and accuracy problems of silica sorting, but also promotes the upgrading of the entire industry chain,also promoted the improvement of resource utilization efficiency and green transformation.In the future, with the deep integration of artificial intelligence and big data technology, the value release of silica resources will move towards higher dimensions, injecting strong impetus into the global energy transformation and digital economy.
