Coal-measure mudstone is a typical dual-porosity media, and grouting in a matrix system is dominantly controlled by the imbibition effect for silica sol. This paper studies the imbibition effect using mudstone in the Huaibei mining area and silica sol as grouting material as an example. Groutability, driving force, and diffusion difficulty affecting the imbibition effect …

Silica sand deposits are most often surface-mined in open pit operations but dredging and underground mining are also used. For industrial applications, deposits of silica yielding products of at least 95% quartz (SiO 2) are preferred. The production of such high purity sand requires that the extracted ore undergo significant processing to ...
Illegal silica sand mining is happening in more than 70 countries (Rege and Lavorgna, 2017). Countries such as China, India, and Singapore with high growth rates need a large amount of silica sand to expand their high-tech industries (Ioannidou et al., 2020). This demand has increased silica sand price, making illegal trades more attractive.
For industrial applications, deposits of silica yielding products of at least 95% quartz (SiO 2) are preferred. The production of such high purity sand requires that the extracted ore undergo significant processing to reduce impurities through the flotation of gangue minerals such as iron, aluminum and magnesium away from the silica.
