Bauxite is usually strip mined because it is almost always found near the surface of the terrain, with little or no overburden. As of 2010, approximately 70% to 80% of the world's dry bauxite production is processed first into alumina and then into aluminium by electrolysis.

Concretions are masses of mineral matter formed when minerals in water are deposited about a nucleus (such as a leaf or shell or other particle) forming a rounded mass whose composition or cement is usually different from the surrounding rock. This can occur at the time of deposition, shortly thereafter, or after the sediment has hardened.
The early modern period of Sri Lanka begins with the arrival of Portuguese soldier and explorer Lourenço de Almeida, the son of Francisco de Almeida, in 1505. In 1517, the Portuguese built a fort at the port city of Colombo and gradually extended their control over the coastal areas.

Abstract. The petrology, mineralogy and geochemistry of a section of the Merensky Reef at Bafokeng Rasimone Platinum Mine (BRPM) are described. A model for the formation of platinum-group minerals (PGM), sulphide and chromitite is proposed that explains the stratigraphic relationships observed in the Merensky Reef, both at BRPM and at other locations in the Bushveld Complex.

Ilmenite produced in China’s Panzhihua Province is unsuitable for chloride route pigment production due to high levels of contaminants (particularly MgO) which lower its reducibility (Lu et al., 2016). Ilmenite concentrates with lower ilmenite levels, may also contain valuable trace minerals like rutile and zircon.
