PY - PUBLICATION YEAR: 1945 LA - LANGUAGE: Spanish AB - ABSTRACT: El Carmelo chromium deposit, Envigado, Antioquia department, Colombia. Chromite occurs associated with serpentine minerals in an altered peridotite. A study of chemical analyses shows that although the tenor is low, the ore is usable because of the ease of concentration and purification.

Investigations were made at several points along the Pajaritos stream to determine the value of a stibnite-bearing vein along a fault plane between two schists. In spite of irregular and low tenor, as well as other exploitation difficulties, the deposit may be workable due to associated gold and silver.
