The main objective of study was to appraise the degree of contamination and human risk assessment due to barite mining. Results showed that the average concentrations of Fe, Hg and Pb were above the required standard. This indicates anthropogenic inputs from barite mining activities. The mean concentrations of Ba, Hg, Mn, Ni, Pb and Zn were ...
Barite Project Scoping Report with Assessment – December 2021 1 EXECUTIVE SUMMARY Mr. Jacobus Petrus Smit (hereafter referred to as the proponent), plans to mine barite within four mining claims on the Steilrand Mountains, northwest of Opuwo, in the Epupa Constituency of the Kunene Region.
The recovery of barite deposits by open-pit surface mining has generated several quarries within the area of study that are several kilometers long and 10-50 m deep.Open cast mining of barite in the study area was carried out without an environmental impact assessment (EIA) study, thereby resulting in poor waste management.
will serve for future impact assessment for adequate planning of mining and farming areas. The main goal of this research is to investigate the impact of quarrying, mining, and cultivation activities on stream sediments by PTEs contents. This goal is achievable through the following spe-cic objectives: (1) evaluation of PTEs concentra-
number of closed barite mining operations. The sample sites are the only abandoned barite mines that are still in existence in the state of Benue (Fig 1). The mining regions are dispersed throughout the various slopes of four local authorities. The bulk of the locations have been abandoned by 2012. The first mining operations started in 2010. The

In the present investigation, the concentration of heavy metals (As, Ba, Fe, Hg, Mn, Ni, Pb, Zn) in pond and stream water samples near abandoned barite mines have been studied. The main objective of study was to appraise the degree of contamination and human risk assessment due to barite mining.
An assessment of the impacts of abandoned barite mines on the environment was environment was carried out in this work. A total of 40 soil samples collected at varying depths of 0cm-15cm and 15cm-30cmwere collected to analysed for their heavy metal contents.
Four (4) water samples from hand-dug wells close to abandoned barite mining sites were tested for heavy metals. The Chronic Daily Intake (CDI), Hazard Quotient (HQ), and Hazard Index (HI) for adults and children were calculated using non-carcinogenic risks.
Over 90% of barite mining activities in Nigeria are carried out by artisanal and small-scale miners (ASMs), and up to 75% of these miners operate informally, without mining license and rights.
