ELKO, Nev. – The Bureau of Land Management (BLM), Wells Field Office (WFO) issued a Decision Record (DR) and Finding of No Significant Impact (FONSI) for the Environmental Assessment that analyzed the impacts of multiple Plan of Operations amendments submitted to for the Big Ledge Barite Mine.

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 …

assessment of either U.S. or global barite resources has been conducted since the 1980s. Substitutes: In the drilling mud market, alternatives to barite include celestite, ilmenite, iron ore, and synthetic hematite that is manufactured in Germany. None of these substitutes, however, has had a major impact on the barite drilling mud industry.

An evaluation of the impacts of various heavy metals in the water on the hazard to human health was undertaken to ascertain whether the water from hand-dug wells close to abandoned barite mines in the research region was safe for human consumption. Analyses of the health risks connected to heavy metal exposure in humans through diet, skin …

The chronic daily intake assessment and health quotient analysis revealed that the accumulation of lead and barium is possible and can initiate chronic diseases in humans over a long time and certain safe mining protocols and controls are recommended. Barite, used in mud formulation, is mined in several places to support the industry. …

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.

Combining environmental isotope analysis with principal component analysis can be an effective method to discriminate the inflows and sources of contamination in mining-affected watersheds. This paper presents a field-scale study conducted at an acid mine drainage (AMD)-contaminated site adjacent to a pyrite mine in South China. …

The exploration and mining of Nigerian barite are primarily by artisanal and small-scale miners (ASM) whose operations are characterized by poor productivity.

This report presents a streamlined remedy assessment for removal actions at an acid pit at the Barite Hill Mine. The Barite Hill Mine is an abandoned open pit gold mine located three miles south of McCormick, South Carolina. It was operated as a surface mine with cyanide heap-leaching for gold recovery from 1991 until 1995 when mine reclamation
