river sand in self-compacting concrete [25]. Optimum replacement level of silica sand was arrived from fresh and hardened concrete properties [26]. A 5% replacement of silica sand with the river sand gives a better compressive and flexural strength [27]. Optimum silica sand replacement level for cement was found to be 6% by weight of cement [28].

Foundry sand is also a great option, as it comprises high-grade quartz that can resist heat and withstand the molten metal's pressure. Stucco sand is also a reliable choice, as it is composed of finer grains, which makes it easier to shape and manipulate. ...
1. Flotation separation of mica minerals and silica sand. Mica dissociates a large number of anions O2- and F- with extremely low zero electric points. After being exposed to the layered structure, they can be recovered with cationic collectors in a wide pH range (pH=2-13). The pH range of feldspar in the cation collection system (pH=4-11) is ...
Abstract. Silica is the name given to a group of minerals composed of silicon and oxygen, the two most abundant elements in the earth's crust. Silica is found commonly in the crystalline state and ...
Nanosilica particles were produced from silica sand using the sol–gel process with a high yield suitable for silica nanoparticle production on the industrial scale at one ton per hour. The structural analysis revealed that the synthesized materials were nanosized (16–37 nm) and highly pure (99.9% SiO 2). As a result of using nanosilica as …
Abstract The amorphous mesoporous silica was successfully synthesized from Jordanian desert glass sand sources. Sodium silicate solution (SSS) was synthesized from glass sand, then silica nanoparticles (SNPs) was synthesized, using sodium silicate solution as a precursor by sol-gel method. The synthesized mesoporous silica has a …
