Improved roasting of some colombian gold ores
This article shows the main results after roasting a gold ore with electromagnetic waves. A mineral sample from southern Bolivar (Colombia) was chosen, due, among other reasons, to the difficulty that miners from that zone tend to have when trying to recover the gold by traditional means.

Se escogió una mena del sur de Bolívar (Colombia), debido entre otras razones, a que los mineros de dicha zona suelen tener problemas para recuperar el mineral precioso por medios tradicionales. Se encontró que al aplicar ondas electromagnéticas en el rango de la microondas, el tiempo de tostación se redujo entre el 77 y el 83%, una disminución promedio cercana al 88% del consumo de energía eléctrica y se logró una recuperación de aproximadamente el 90% (peso/peso) de la obtenida con una tostación tradicional a nivel de laboratorio. Esto indica que es una alternativa que justifica estudios más profundos a escala de planta piloto.application/pdfspaUniversidad Nacional de Colombia Sede Medellínhttp://revistas.unal.edu.co/index.php/dyna/article/view/28073Universidad Nacional de Colombia Revistas electrónicas UN DynaDynaDyna; Vol. 80, núm. 178 (2013); 70-77 DYNA; Vol. 80, núm. 178 (2013); 70-77 2346-2183 0012-7353Amaya, Iván and Bernal, Danilo and Garnica, Sergio and Reslen, Mauricio and Correa, Rodrigo (2013) Improved roasting of some colombian gold ores.

This article shows the main results after roasting a gold ore with electromagnetic waves. A mineral sample from southern Bolivar (Colombia) was chosen, due, among other reasons, to the difficulty that miners from that zone tend to have when trying to recover the gold by traditional means. It was found that after applying electromagnetic waves in the microwaves range, roasting time was reduced by 77 to 83%, on average decreasing the consumption of electrical energy by about 88%, while allowing gold recoveries of about 90% (w/w) of that achieved through traditional roasting. This indicates that it is an alternate treatment worth deeper exploration at pilot plant scale. |
