Abstract. The main objective of bauxite beneficiation is to lower the concentration of reactive silica, in the form of kaolinitic clay, and also to increase the alumina content. Additionally, reduction in iron content, particularly in the form of goethite, and reduction of organic carbon can also increase the value of the bauxite product.
Pegmatite Li ore and brine lakes are currently the two main Li resources, and clay-based Li ores are being under research (Mohr, Mudd, and Giurco 2012; Tadesse et al. 2019). It is promising that ...

The accuracy of the models developed for the beneficiation of the clay were confirmed by the adjusted R-squared values of 0.94, 0.924 and 0.995 for yield point, plastic viscosity and filtrate volume respectively, alongside with the comparison of the experimental and model prediction results. The best conditions for treating the clay was been ...
Clay has its widespread applications in pharmaceuticals from ancient world to modern era. It is one of the excellent excipients present in the commercially available pharmaceuticals. Its use in many of dosage forms viz. in suspension, emulsion, ointments, gels, tablet and as drug delivery carrier as suspending agent, emulsifying agent, stiffening …

Heavy metal contamination of clay waste through the phosphate beneficiation process is a serious problem faced by scientists and regulators worldwide. Through the beneficiation process, heavy metals naturally present in the phosphate rocks became concentrated in the clay waste. This study evaluated the concentration of heavy …
Black shale ore contains rich strategic metal resources such as vanadium, nickel, and molybdenum, but due to its complex composition, it is currently only used in the vanadium extraction industry. Metals such as nickel and molybdenum have not been effectively recovered, resulting in environmental pollution and resource waste. Using …
Lithium (Li)-bearing clays have become new types of Li resources, and it is found that the evolution of the mineral structure in Li-bearing clay greatly restricts the extraction of Li. Herein, a Li-bearing clay from Guizhou Province, China, was studied using in situ thermogravimetry–differential scanning calorimetry–mass spectrometry–Fourier …
Beneficiation of the bentonite ore. The results of beneficiation showed that applying a flowsheet based on attrition scrubbing of the crushed bentonite ore followed by classification with a hydrocyclone succeeded in removing much of the associated quartz and calcite as an underflow (about 15 wt.%) fraction. So, this underflow fraction was ...
The beneficiation of the clay using sodium carbonate and Kelzan® XCD polymer ensued in an improvement in the rheological properties of the formulated drilling mud. These properties were ...

The clay containing below 45 μm is mostly brittle, causing beneficiation problems. The IOF has an LOI of 7.83%, with high silica (5.52%) and alumina (4.57%), and 57.17% of Fe(T) subjected to both conventional deep beneficiation (CDB) and magnetization roasting using high-ash non-coking coal to adopt the suitable upgradation …
Surface pH Measurement: Suspensions (20% eficiated (wet method) clay and the Na-treated clay was w /v) of the samples (DS, WS and STS) were carried out using lithium metaborate (LiBO2) fusion prepared and allowed to stand for 0.5 hr with digestion technique followed by analysis with the aid of occasional stirring with a glass rod.

The clay has poor plasticity and high refractoriness. Primary clay is mostly composed of a micro-crystalline kaolinite compound (Al 2 O 3.2SiO 2.2H 2 O) . Kaolin is a lightweight, soft sedimentary rock, having chalk-like properties and an earthy odour. It is made up of about 90% kaolinite mineral . It typically contains quartz and mica.
