The beach sands along the coasts of India contain large reserves of strategic minerals like ilmenite, monazite, zircon, etc. Monazite mineral is primarily used as an ore for extracting rare earths particularly cerium and lanthanum. In the present study, the chemistry and distribution of monazite found in the beach sands of Neendakara–Kayamkulam belt in Kerala, …
It has long been established that REE deposits are associated with late hydrothermal activity in and around carbonatites due to ubiquitous sub-solidus alteration (4, 8, 10–13).Aureoles of REE-rich sodic or potassic metasomatic alteration, or fenites, are common around carbonatites and can extend up to 4 km from the main intrusions (10, 13).No unified model explains all features of ...
Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO 2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses.
A novel sinter method using ZnO as the activator instead of the conventional Na 2 CO 3 /CaCO 3, (NH 4) 2 SO 4, and K 2 S 2 O 7 was developed to achieve efficient sequential extraction of rare earth elements (REEs), alumina (Al), and silica (Si) from coal fly ash (CFA). Up to 93.3% Si, 87.1% REEs (70.7% Ce, 82.5% La, 83.2% Gd, 87.1% Nd, 62.3% Dy, and 81.7% …
The plan considers five minerals (with estimated value of deposits) to be strategic: non-radioactive rare earth elements (NR-REE) such as lanthanide elements[6] (RM747.42 billion); bauxite (RM20.3 billion); tin ore …
Four conventional mineral deposit types—carbonatite, alkaline igneous, heavy mineral sand, and regolith-hosted ion-adsorption clay deposits—currently supply global …
The total concentrations of rare-earth elements (REE) in the mined kaolin (0.02–0.06 wt.%), kaolin mine tailings (0.03–1.9 wt.%), and the kaolin-associated Marion Member sand lithology (0.03–4.6 wt.%) opened questions regarding the modes of occurrence of the REE and the role(s) of chemical weathering and secondary processes to explain the presence of …

Garnet sand, after being used as an abrasive in the cutting and sandblasting industry, is recycled several times before it is finally considered waste which eventually must be disposed of....
Silica is also found in the Earth's crust. The type of silica used to make cell phone chips is an ultra-refined and inherently delicate form of silicon dioxide particles. These important silica sand deposits are found in places like Queensland, Australia, as well as Mid-Atlantic states in the U.S., like North Carolina and ia.
These rocks are extracted from the ground and turned into quartz gravel, which is then processed into a fine sand. The silicon is separated from other minerals and then goes through a final ...
The tenement was acquired to explore and develop silica sand, but numerous recent nearby discoveries of REE clay-hosted deposits nearby prompted Allup to consider the potential for such deposits on its tenement. ... In this province, a number of carbonatites with rare earth potential have been reported and explored for rare earth mineralisation.
The tested material in this study was F35 sand—a coarse, rounded silica sand composed of over 99% SiO 2 quarried at Ottawa, Illinois purchased from U.S. Silica.
A 3D- technique has been developed to create high-quality pure silica nanostructures with sub-200 nm resolution and the flexible capability of rare-earth element doping. It shows excellent ...

Solid pollution has been an issue in mineral processing for decade. One of these pollutants is zircon sand mining waste (zircon tailing). Due to the concentration of rare earth minerals in zircon tailing and the increasing demand of REE in advanced technologies, studying zircon tailing as a potential source of REE had become an interest for us.
Singing sand produces sounds even if it is removed from the dune to a laboratory. Sand from dunes that don't sing in nature can't be made to sing in the lab. Singing dunes are usually composed of well-rounded very fine to medium silica sand grains (100–500 microns) with surfaces roughened by pitting from aeolian transport.
The unique properties of rare earth elements (REEs) (Fig. 2.1) make them useful in a wide variety of applications, such as alloys, batteries, catalysts, magnets, phosphors, and polishing compounds.The REEs and their primary uses by manufacturing sector are covered in Table 2.1.Four main geologic types of REE resources supply REEs and rare earth oxides …

Silicon is rarely found free in nature; it combines with oxygen and other elements to form silicate minerals. These silicate minerals compose more than 90 percent of Earth's crust. Silicates are the largest class of rock-forming minerals on Earth. Silicon dioxide, or silica, typically takes the form of quartz, the most common component of sand.
