Limestone uses — Science Learning Hub

Calcium oxide, obtained from limestone, acts as a pH regulator when extracting gold from quartz. The chemical extraction of gold from powdered quartz rock uses a solution of sodium cyanide. In this cyanidation process, the pH of the solution needs to be maintained between 10–11 to prevent the production of deadly hydrogen cyanide gas. The addition of calcium oxide to the solution maintains

Lime use and functionality in sulphide mineral flotation: A review

The decarbonation process of expelling CO 2 from calcium carbonate happens on a migrating front starting on the limestone surface within the calcination kiln. The exterior of the stone decarbonates first, due to the fact that limestone and lime are poor heat conductors. The heat then penetrates deeper into the stone enabling further thermal decomposition (core-shell model). The purpose of
