Mining | Water for all

Different chemicals work better under different conditions: for example, under high flow conditions, pebble quicklime and ,hydrated lime, are the most cost effective. Furthermore, AMD from each mine is unique due to the different combinations of acids and metals, and needs to be analyzed so the chosen chemicals are the best tailored to neutralize the specific acids and metals present [23].
