In the mining region of Pachuca, Mexico, waste from the mining industry have been generated for more than 100 years, which have a high SiO2 content that can be recovered for various industrial applications. This 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.Country-specific carbon footprint and cumulative energy

Waste gypsum–blast furnace slag cement in mortars with granulated
The use of BFS sand was more effective than silica sand in terms of strength, due to the reaction of the BFS sand. The porous nature of the BFS sand trapped water that served as a reserve for further BFS reactions and strength gain. 4. The properties of the BFS mortars are of low cost, good properties and environmentally friendly.That sand was valued at $4.2 billion, averaging about $56 per metric ton. Hydraulic fracturing, not the glassmaking industry, is now the leading use for industrial sand, as 72 percent of the sand mined in 2014 was used for hydraulic fracturing and well-packing. Thirteen percent of the industrial sand mined in 2014 was used for glassmaking,Environmental Impacts of Industrial Silica Sand (Frac

This current study reviews the utilization of the traditional extraction methods and latest findings in extraction of silica from agricultural wastes, in particular, sugarcane bagasse, using inorganic acids to produce nano-silicon. The three key processes discussed in detail include electrochemical, ball milling, and sol–gel processes. The The effects of silica sand proportion in color changing and penetration depth of the samples after laser scabbling process were studied. Furthermore, the generation of micro-cracks and pores were observed by using scanning electron microscopy (SEM). In addition, chemical composition changes between processed zone and non The Effect of Silica Sand Proportion in Laser Scabbling Process

Innovative technology for the production of high-purity sand silica
As a mineral substance, silica (SiO2) is made up of silicon and oxygen, the two most abundant naturally-occurring elements [16]. Silica sand is a natural white ceramic material with a high purity of silica (up to 99%) [17]. Hence, silica sand can be considered as a potential ceramic material in membrane fabrication technology.Sand mining is the process of extracting sand from an open pit, sea beaches, rivers and ocean beds, river banks, deltas, or inland dunes The extracted sand the silica sand met the prescribed standard range of over 90% of particle size within the 15–100 mesh (BS sieve number) [50] Minerals 2020,10,448 7 of 13Gold Mine Tailings: A Potentialadvantageous effect of mining silica sand przegladbiznesu.eu
