Abstract
Description
La escasa difusión de las técnicas petrograficas y analíticas en el medio minero Colombiano, permite que se siga trabajando con el esquema tradicional de ensayo y error en el estudio de los depósitos metálicos y en el beneficio de minerales. Las técnicas petrograficas y analíticas son importantes porque permiten establecer las características de un deposito aurífero, asociaciones mineralógicas, liberación y/o exposición de sulfuros y metales preciosos. Con los datos generados sobre mineralogía, composición y texturas de los minerales valiosos y de ganga, los procesos de beneficio de los metales preciosos y sulfuros de interés pueden ser optimizados, eliminando pruebas innecesarias.
The lack of application of ore petrography and analytical techniques in the history of Colombian gold mining makes the miners continue working with the traditional method of trial and error in the study of the metallic deposits and in the recovery of precious metals. The petrography and the analytical techniques are important because they allow establishing the characteristics of gold deposits and other precious metals, mineralogical associations, liberation condition and sulfide exhibition. With the data generated on mineralogy, composition and textures of the valuable minerals and gangue, the metallurgical processes of recovery of the precious metals and sulfide of interest can be optimized, eliminating unnecessary tests.
