Selective leaching of nickel from prereduced limonitic laterite under moderate HPAL conditions- part I: Dissolution [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2016 High pressure acid leaching (HPAL) is the primary method for extraction of nickel from limonitic laterite. The severe operating conditions, the complexity of facilities, and several technical problems, such as scale formation, have always ...

Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil
Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Kinetics of phosphorus sorption by goethite and kaolinite‐goethite (k‐g) system
Communications in Soil Science and Plant Analysis, 1998 Abstract Reactions between phosphate (PO4) and soils or soil components is quick at first. It then becomes slower and continues for long time without reaching any true equilibrium. Many kinetic equations have been used either to deduce the mechanisms or simply to summarise results of this continued removal of PO4 from solution.

Advanced Functional Materials, Volume 36, Issue 6, 19 January 2026.This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...
