environmental impacts of slag clashing plants

Characteristics and environmental aspects of slag: A

Slag is a waste product from the pyrometallurgical processing of various ores. Based on over 150 published studies, this paper provides an overview of mineralogical and geochemical characteristics of different types of slag and their environmental consequences, particularly from the release of potentially toxic elements to water.get price

Environmental impact of ferrochrome slag in road construction

The long-term environmental impact of the ferrochrome slag should be compared to that of Cr-rich bedrock. However, the knowledge of the environmental impact of the Cr-uptake by plants is very limited. The presence of Cr(VI) is related to complex bio/geochemical processes involving Fe, Mn organic matter and sulphides.get price

Bottom ash Energy Education

Health EffectsEnvironmental EffectsDisposal and RecyclingFor Further ReadingCoal ash (which includes bottom ash) can have a different chemical makeup depending on where the coal was mined. Broadly speaking, coal ash is a pollutant, and it contains acidic, toxic, and radioactive matter. This ash can contain lead, arsenic, mercury, cadmium, and uranium. The EPA found that significant exposure to bottom ash and other components of coal ash increases a person's risk of developing cancer and other respirSee more on energyeducation.ca

Chromium as an Environmental Pollutant: Insights on

In the past decades the increased use of chromium (Cr) in several anthropogenic activities and consequent contamination of soil and water have become an increasing concern. Cr exists in several oxidation states but the most stable and common forms are Cr(0), Cr(III) and Cr(VI) species. Cr toxicity in plants depends on its valence state. Cr(VI) as being highly mobile is toxic, while Cr(III) asget price
