Levels of PTEs contamination are elevated in cultivation areas more than in granite quarrying and mining areas and the use of multiple pollution indices such as I-geo, EF, EiR, and RI in pollution assessment indicated similar trend of P TEs contamination of stream sediments. This study assessed the contamination of streams with potentially …

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-

in Pakistan was poor, but recently production of barite increased to 75,000 metric tons; this promotes Pakistan from 12th to 8th rank in the world as producer of barite (Jewell and Kimball 2015). Pakistan's barite has a good demand in the international market. Persons involved in mining and processing of barite are often affected from the

"The ruby mine is located in Surobi District of Kabul, covering an area of 6.8 square kilometers, with a total investment of $27.5 million on this mine," the acting minister of Mines and Petroleum added. Some of the investors who have invested in these mines pledged that the mining processes will also be carried out within the country.
Downloadable! 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. Such mining activities endanger human lives through the uncontrolled release of toxic heavy metals and other pollutants which are major causes …

barite mining in Nigeria due to Federal Government's policy of using local raw materials. This resulted in many legal and illegal mining of barite, a major component used in the oil and gas indus-try in Nigeria. The mining and processing of barite generates vast quantities of mine rocks and mine tailings. Barite has been mined
The Fireside mine contains some of the purest barite on the market. Approximately 77% of the total mined and milled barite worldwide is used as a weighting agent for drilling fluids in oil and gas exploration. In this process, barite is crushed and mixed with water and other materials. It is then pumped into the drill hole.
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.
The exploration and mining of Nigerian barite are primarily by artisanal and small-scale miners (ASM) whose operations are characterized by poor productivity. As a result, the quantity and quality of barites produced do not satisfy the nation's oil sector demands and other industries that require the mineral. This situation leads to massive …
