kaolin ore mining
Kaolin | Energy & Mining
The bulk of the ore is pale yellow to white sandy kaolin used in general cement manufacture. High-grade zones comprise masses of almost pure kaolin up to 50 m wide, 30 m deep and ~100 m long. Variable and unpredictable iron-oxide-stained patches dictate selective mining to produce white kaolin which is used in white cement manufacture by ...

The Lightner Mine near the town of Spottswood opened in 1940. Underlain by limestone of the Conococheague and Stonehenge Formations, bauxite and kaolin have formed within residuum. A pit 10-40 feet deep and 200 feet long was dug into the kaolin and bauxite-rich ore body to expose ore of up to 57.5 percent aluminum oxide (Al 2 O 3).

Rubidium extraction from mineral and brine resources: A review
A chlorination roasting process was proposed by Zheng et al. (2016) to recover the rubidium from the kaolin ore. A 96.9% of rubidium extraction was obtained at a mass ratio of kaolin to CaCl 2 of 2:1 and the roasting temperature of 800 °C. Kinetic studies showed that the extraction efficiency of rubidium was controlled by the roasting reaction.
