Abstract
The authors appraise application of milky quartz from the Larino lode deposit in production of high-purity quartz concentrate with the total content of impurities less than 50 ppm. The structure and texture of milk quartz are analyzed using the optical microscopy and ICP-OES spectrometry methods. The elemental analysis data of the preconcentration and deep concentration products are compared. The low contents of the impurity elements in the deep concentration products of quartz from most lodes of the Larino deposit prove the applicability of this quartz material as a feedstock for the production of high-purity quartz concentrates.
