Leaching of Chalcopyrite under Bacteria–Mineral Contact/Noncontact Leaching Model

, 2021
Bacteria–mineral contact and noncontact leaching models coexist in the bioleaching process. In the present paper, dialysis bags were used to study the bioleaching process by separating the bacteria from the mineral, and the reasons for chalcopyrite ...

Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

Advanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...

Soil mineralization: An emergent process?

Geoderma, 2010
Abstract This paper argues that soil mineralization should be seen as an emergent process. While it is effecting mineralization the soil population shows many of the characteristics of recognised emergent systems such as ant colonies and slime moulds.

Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

Advanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.

Steering Oxygen Activation Pathways via Redox Dual‐Defects in 2D Hydrated WO3 for High‐Yield Singlet Oxygen Evolution

Advanced Functional Materials, EarlyView.
Redox dual‐defects (Cs substitution and O vacancies) in 2D hydrated WO3 steer O2 activation toward selective singlet oxygen evolution. WO‐CO achieves 8.6–15.8 times higher 1O2 production than single‐defect or pristine catalysts, enabling efficient pollutant mineralization via a pathway‐selective photocatalytic mechanism.

Applications of biological processes in mineral processing

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1998
Abstract Biological processes have been attracting attention in mineral processing recently due to lower operating costs and their possible applications in processing low-grade ores that are not easily concentrated using conventional processes. Adhesion of microbes to particle surfaces can alter the hydrophobicity of minerals markedly.
