Slaked lime is an indispensable reagent in differential flotation. But there has been much trouble over the quality of slaked lime in many flotation plants. Lime is used in flotation pulp as the pH regulator, the pyrite depressant, the neutralization reagent, the flocculation reagent, etc. When lime is used for a flotation reagent it must be dissolved as soon as it is added in the pulp. From the test on dissolution of lime, it was found that the content of calcinm was not necessarily proportional to the effectiveness of lime as the flotation reagent. At the Taro flotation plant, the consumption of commercial lime is generally proportional to the content of Ca(OH)_2. The quality of commercial lime as the flotation reagent must, therefore, be indicated by the content of water-soluble Ca(OH)_2 instead of the usual practice of indicating the quality by the content of total CaO.
