Environmental impact of Portland cement production ...

2013-1-1 · The grinding process impacts the cement manufacture in at least two ways. First, an increase of the fineness and homogeneity of the raw mix accelerates the clinkering reactions, leading to less variability of the clinker due to the enhanced stability of the kiln and better energy efficiency in producing a clinker of better consistency.

The environmental impact of gold production

2019-7-25 · The stages that contributed the most to gold’s environmental impact were mining and comminution (crushing and grinding of the ore). Electricity use was responsible for just over half of the GHG emissions. This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages. Mining and comminution are highly dependent on the grade of gold ore, as the lower the grade, the greater the amount that needs to be mined and the more crushing and grinding
