Law of gas migration and enrichment in goaf based on three-dimensional porosity model
Meikuang Anquan, 2021 The distribution of porosity in the goaf has an important influence on the fluid flow in the goaf. Based on the O-shape ring theory and the masonry beam theory, a three-dimensional distribution function of porosity was proposed.

Concentration of bauxite fines via gravity concentration [PDF]
Rem: Revista Escola de Minas, 2009 Companhia Brasileira de Alumínio (CBA) has a preparation plant at Itamarati de Minas, MG. This plant washes two different kinds of bauxite ore, one originating from the laterization of gnaisses and another from amphybolites. Both ores have the same behavior in the coarser size fractions but behave differently under 0.355 mm (42# Tyler).
