This paper presents the research undertaken in order to establish a processing technology for the Budureasa dolomitic limestone. For this, a series of physico-chemical and mineralogical analyzes were performed, but also unitary processing operations such as grinding, calcination, gravitational concentration and flotation, and solubilization with carbon dioxide in an aqueous medium to obtain a MgO ? rich concentrate, usable in various fields of activity, under economic efficiency conditions. Mineralogical, chemical...
