The dolomite deposit coexists with limestone (nearly 100% calcite) deposits in many cases in Japan. The mixing of limestone ore is inevitable in quarrying operation of dolomite ore and it is one reason to degrade the MgO grade of dolomite ore. Removing limestone from dolomite ore is, therefore, effective for upgrading the MgO content of products. However, as the mineralogical structure and phys. characteristics of dolomite mineral are similar to those of calcite, a fine grade separation of the both mineral particles is generally presumed to be difficult and practicable method for the beneficiation of dolomite has not been reported. A method for beneficiation of low grade dolomite ore is, herein, investigated for effective utilization of dolomitic resources in Japan. In order to meet the requirements from industries, the grade of MgO component of processed dolomite is targeted to be 19.0% or more in this research. The targeted grade for beneficiation was achieved by froth flotation with a cationic collector, i.e. Dodecylamine Acetate (DAA). Results of the flotation and the effects of other parameters influencing effectiveness of floatation and phenomenon observed in the floatation experiments of dolomite ore are herein reported.
