Types of Calcium Reagents and Their Application in Acid Mine .using lime for the treatment of mine drainage. Waters containing more than 500 mg/l of sulfates, sulfites, or bisulfites are considered unsuitable for slaking. Calcium reagent costs can differ greatly, as can their relative utilization efficiency in a given process. Low reagent cost does not always equate to lowest operating cost if.slaking process for mining,Lime (material) - WikipediaBurning (calcination) converts them into the highly caustic material quicklime (calcium oxide, CaO) and, through subsequent addition of water, into the less caustic (but still strongly alkaline) slaked lime or hydrated lime (calcium hydroxide, Ca(OH)2), the process of which is called slaking of lime. Lime kilns are the kilns used.

Lime Treatment of Acid Mine Drainage in Canada - InfoMine

Lime dissolution is the first step of the neutralisation process. For large treatment systems, quicklime is used. This lime must first be hydrated (slaked) and is normally fed to the process as a slurry. The hydrated lime then dissolves to increase pH. The two following equations illustrate these reactions: CaO + H2O ⇒ Ca(OH)2.
