Lime use and functionality in sulphide mineral flotation: A 2019-11-01& 0183;& 32;Lime plays a critical role in flotation by controlling pulp chemistry and collector adsorption. Lime is the most economical and commonly used reagent for pH control in flotation. Ca 2 ions in lime can enhance depression of minerals and flotation selectivity in a variety of ores.. For talc- and clay-rich ores Ca 2 ions can be detrimental and other pH modifiers are preferred.

Froth Flotation Process - Detailed Explanation With The method of froth floatation can be classified into three steps: 1. True floatation – In this process minerals are selectively attached to froth. This process is very critical and important as the extraction of the valuable minerals is decided by this step only while the other two steps determine the separation efficiency between the mineral and the gangue.
