bauxite deposits lie along the valleys of Commissioners Creek and Big Sandy Creek in Wilkinson County. The kaolin lenses are much larger than the bauxite deposits; some of the lenses underlie more than 200 acres and are more than 20 feet thick. Bauxite was discovered in the district in 1907 and was mined from 1910 to 1928.
Introduction. In companion papers, Taylor et al.(Citation 2008), described the general features of the Weipa bauxite deposit, its landscape setting, regolith profile, climate and previous research.Then, Eggleton et al.(Citation 2008a) described in detail each component of the regolith profile at East Weipa and Andoom from the bedrock—Rolling Downs Group (Andoom) …
The kaolinization of bauxite has generally been thought to be a simple process of epigenetic resilification. A study of the karstic boehmitic bauxites in the Vlasenica region of Yugoslavia, however, shows that kaohnization took place in a rather complex manner, in which the alteration was caused by the percolation of siliceous water descending through the deposit by means of …
Abstract The first Phanerozoic bauxite appeared in the Early Cambrian in isolated areas of fold belts during their peneplenization. Commercial deposits of high-quality bauxite were formed in the Northern Urals during the Eifelian. In the Frasnian, bauxite accumulation expanded to the Central Timan. The number of known Devonian deposits does not exceed two dozen, …

D-K-type bauxite from Guizhou can be used as an unburned ceramic, adsorbent, and geopolymer after low-temperature calcination. It aims to solve the problem where the color of the D–K-type bauxite changes after calcination at different temperatures. Digital image processing technology was used to extract the color characteristics of bauxite images after 10 min of …

Kaolin is a rock from which the clay mineral kaolinite is derived. This one has been used for millennia as the principal ingredient in porcelain tableware. Today Imerys kaolins bring critical properties to a host of end applications ranging from paper to paints, fiberglass to cosmetics and pharmaceuticals.
Az-Zabirah low-grade bauxite and kaolin mine is located in Hail Province, sixty-five km north of al-Baaethah and eighty km south of the town of Turubah. The site consists of an open pit mine as well as processing facilities. Operations at the mine began in 2008 with the supply of low-grade bauxite to local cement companies.
The above tripartite subdivision of kaolin has been established so as to be in accordance with other lithologies which formed through magmatic, sedimentary, and metamorphic processes and to link the present classification scheme directly with the "Chessboard classification scheme of mineral deposits" (Dill, 2010b). While in many classification schemes …

Kaolin and bauxite with a high content of Th [23,24] are being exploited near the DL11 site in Trai Mat-Da Loc [25] and these activities may cause the highest Zn and Th concentrations in the ...
The open-circuit flotation results also show that a bauxite concentrate with m(Al2O3)/m(SiO2) over 9.3 and Al2O3 recovery over 76% can be obtained from diasporic-bauxite ore.
Mixing kaolin, bauxite and ball clay in the ratio of 7:2 produced a cold crushing strength of 33 MN/m2. Linear shrinkage decreased with increase in kaolin, but increased with increase in bauxite. All the mix ratios of kaolin and bauxite clays produced linear shrinkage values within the ASTM C133 range of 4-10% though 7:2 yielded the lowest value.
The mixtures of bauxite with kaolin and serpentinite/olivinite (samples M34, M35, M38, M39) have shown progressive melting, which began by firing at temperatures up to 1300 °C for one hour, whereas in the case of the mixtures of bauxite with kaolin and magnesite (samples M48 to M53) up to 1350 °C for two hours. By the mixtures of the bauxite ...
