Abstract
Antioquia, in which, from a magnetic separation and flotation, feldspar for the ceramic industry can be obtained.2) report on lead and zinc deposits at Valparaiso, Antioquia, with comments on the existence of veins and evaluation of the profitability of their exploitation. 3) report on the study of the Vende Cabezas gold mine in Riosucio, Caldas.
