Watercoal interactions are dominant factors that affect water quality in coal mines. Using lixiviation, the effects of watercoal interactions on pH, salinity, and hazardous elemental enrichment in coal mine water and associated trends were simulated and analyzed. The salinity and hazardous element contents were low in the alkaline solution filtrate. However, the salinity and contents of ...

Geochemical processes and the effects of natural organic solutes on the solubility of selenium in coalmine backfill aquifers were investigated. Backfill and groundwater samples were collected at coal mines in the Powder River Basin, Wyoming. Backfill was generally dominated by aluminum (14,400 to 49,000 mg/kg (milligrams per kilogram)), iron (3,330 to 23,200 mg/kg), and potassium (7,950 to 18,00

Studies were conducted to examine the effect of flue gas carbon dioxide (CO2) on solubility and availability of different metals in fly ash of Powder River Basin (PRB) coal, Wyoming, USA. Initial fly ash (control) was alkaline and contains large amounts of watersoluble and exchangeable metals. Reaction of flue gas CO2 with alkaline fly ash resulted in the formation of carbonates which ...

1. Introduction During industrial production, oils such as lubricating oil and engine oil tend to age and deteriorate due to longterm contact with additives, metal powder, oil chips, and other impurities [1]. Eventually, these oils need to be replaced to avoid damage to equipment and losses in efficiency [2].
