Progress, Challenges, and Perspectives of Bioleaching for
The accumulation of mine tailings on Earth is a serious environmental challenge. The importance for the recovery of heavy metals, together with the economic benefits of precious and base metals, is a strong incentive to develop sustainable methods to recover metals from tailings. Currently, researchers are attempting to improve the Both MIC and bioleaching, are processes characterized by the dissolution of substrata (controlled and uncontrolled). The two well-established bioleaching modes are “non-contact” and “contact” leaching ( Vera et al., 2013 ). The latter takes into account that cells attach and form biofilms on the surface of minerals.Frontiers Editorial: Bioleaching and Biocorrosion: Advances

Alternative Methods of Extracting Metals (GCSE Chemistry)
2 天之前Phytomining and bioleaching are extraction techniques. In order to extract copper, we can use extraction techniques such as phytomining and bioleaching. These extraction techniques are less harmful to the environment. Extracting Metal Compounds Phytomining. Phytomining uses plants.Copper is a wildly used resource that can be found throughout modern society. Copper has traditionally been extracted from high grade ores using large scale mining projects.Due to pressures on copper reserves, industries are driven to extract copper from lower grade ores.This has spurred the development of new ways of extracting Biological Methods of Extracting Metals Revision MME

A mini-review of phytomining SpringerLink
Phytomining involves the production of a ‘crop’ of metals by growing high-biomass hyperaccumulators that accumulate high concentrations of metals (Robinson et al. 1999a).In contrast to simple phytoextraction techniques, the goal of phytomining is primarily to realize the economic benefits and commercialization by comprehensive use of The most widespread method for copper biomining is bioleaching: the extraction of soluble copper from complex solid mixtures (Gumulya et al. 2018). Therefore, it is not surprising that bioleaching has been the focus of recent approaches to copper bioremediation (Fonti, Dell'Anno and Beolchini 2016) and recycling (Drobíková et al. 2015).Synthetic biology approaches to copper remediation: bioleaching

Phytomining of rare earth elements A review ScienceDirect
Phytomining has emerged as an ecologically sound technique to extract these valuable elements from contaminated soils where traditional mining is not competitive. This paper presents and reviews the concept of REE phytomining from three scientific areas. namely bioleaching and biosorption (Cui and Zhang, 2008). Bioleaching refers to usingUnlike traditional excavation, phytomining is dependent on growing conditions such as the weather, altitude and soil quality. A bad growing season could wipe out an entire crop of metal-producing plants, and if global climate change alters weather patterns, the risks associated with establishing a long-term phytomining industry in an Advantages & Disadvantages of Phytomining Sciencing

Phytoextraction and bioleaching are principally used for copper extraction due to the high global demand for copper, but these methods can beBioleaching has several advantages that make this technology desirable for metal extraction from mining wastes. Firstly, bioleaching is effective at processing low-grade and refractory ores (e.g., Hallberg et al., 2011), which is advantageous due to the depletion of high-grade ores and ores that are easy to process (Brierley and Brierley, 2013).Review on metal extraction technologies suitable for critical
