PARTICLES ASSOCIATION STUDY OF A BORATE SAMPLE FROM SIJES DISTRICT, ARGENTINA

The increasing range of borate uses, mainly in the ceramic frit market, led borate producers to improve competitiveness through concentration and/or purification steps in the mill circuit as well as in the characterization of high content B2O3 minerals. Minerals coming from Sijes, Salta Province, Ar...
