Antimony (Sb) is a harmful element, and Sb pollution is one of the typical environmental issues in China, meaning that understanding of the geochemical behaviors of Sb is the key to control the fate of environmental Sb pollution. Sb tends to migrate in soluble form in the water–sediment system, but the fate of dissolved Sb is poorly known. …
The Democratic Republic of Congo (DRC) is rich in natural resources – its untapped deposits of minerals are estimated to be worth US$24 trillion.Gold, diamonds, cobalt and zinc are among them.
Antimony is commonly listed as a critical mineral, particularly in the United States and European Union [1]. Its criticality, or supply risk, is derived from a combination of economic vulnerability, disruption potential of supply, and trade exposure [2].Disruption potential relates a country's ability and willingness to supply a commodity.
companies from prosecution related to air quality- issues. This legislation persisted to the mid-1990s. Currently, air quality in areas of the Copperbelt Province and the aquatic habitat in the Kafue River, a tributary to the Zambezi River, are two of the more significant mining environment issues in Zambia.
The Democratic Republic of Congo (DRC), Africa's second-biggest country by land mass, is rich in both those elements. But for much of its recent history, the hunger for minerals has caused environmental …
Majority of antimony-bearing ore deposits are associated with the subduction-related western Pacific plate boundaries, especially in east and south-east Asia. The highest antimony concentrations commonly occur in low-temperature magmatic-hydrothermal systems in the epithermal environment.
Large-scale mining activities have led to many environmental problems, such as heavy metal pollution, among which antimony (Sb) is a relatively new pollutant and is often accompanied by arsenic (As) pollution for Sb mining (E. Álvarez-Ayuso et al., 2012; YanMing Zhu et al., 2020).It was reported that approximately 1315 of Sb and 70 mg/kg …

Companies such as Samsung, Panasonic and Tesla are starting to show a preference for NMC811 batteries that require less cobalt (but more nickel) rather than earlier NMC111 and NMC622 batteries, potentially at least in part due to issues of cobalt sourcing from DRC and the wider socio-economic and political issues involved. 12 The …
Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in …

In February 2022, the World Bank Board of Executive Directors endorsed a new Democratic Republic of Congo - Country Partnership Framework (CPF) for the period of 2022-2026.The CPF promotes the stabilization and development of DRC, supporting strategic priorities and critical reforms to improve governance and deepen stabilization …
Global antimony consumption was estimated to be 160 000 t in 2019 . China is the world's leading antimony producer and also a major user of this metalloid; thus, environmental issues associated with antimony are particularly acute in this country (He et al. 2012). Concurrently, a lot of research is being carried out in China on …

However, according to the due diligence of the Congo region issued by the OECD, the Congolese army's actions by the CMOC to protect minerals will cause controversy.This negative incident will not only cause reputational risks but may also violate the relevant requirements of due diligence. Currently, CMOC's cobalt mines are only …
Antimony is a naturally occurring element. It belongs to the group 15 of the Periodic Table of the Elements. Antimony can exist in a variety of oxidation states (−III, 0, III, V) but it is mainly found in two oxidation states (III and V) in environmental, biological and geochemical samples.
The adverse environmental and human impacts of small-scale and artisanal mining have been studied almost exclusively for gold mining, usually with a focus on the use of mercury 24, but also in ...
