Fortunately, Ba availability is largely limited in the environment due to the high stability of its main salt—barite (BaSO 4; solubility product, K sp of 1.08 × 10 −10 at 25 °C). Still, under certain condition Ba can occur in soluble forms at concentrations much greater than expected from barite solubility (Pluta and Trembaczowski 2001 ...

Some barite mines have a high geological grade and stable quality, so the qualified barite products can be selected by handpicking according to the difference in the color and density between barite and associated minerals. For the rich barite ore selected by hand, the grain size shall be 30-150mm, and the BaSO4 shall be larger than 95% ...

1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The

Coal quality deteriorates when stacked at yards and is prone to fire when stocked for long, leading to heavy losses. Overburden removal increases mine stability and is necessary for ramping up production at open cast mines which accounts for 95% of the company's production. In March, daily average coal production was around 2.7 million tonnes which was reduced to 1.3 million tonnes in the ...

Results show that the abandoned open cast mines plays a dominant role in changing hydrological process and thus watershed hydrology. The potential hydrological impact of these mines is an increased annual lateral flow of2%, annual sediment yield of 16%, decrease in annual surface flow by 51% and, annual water yield by 6% for the Olidih Watershed.

Barite (BaSO4) is a stable and widely distributed mineral in Earth's crust. As such, barite has the potential to preserve specific geochemical and morphological characteristics representative of conditions at the time of its formation, which could be useful for interpretations of Earth's ancient rocks and paleoenvironments. In this study, we used variations in saturation index, solution ...
