HOW TO AVOID CHEMICAL AGRESIVE SUBSTANCES IN WASTE WATERS FROM GOLD JEWEL PRODUCTION
Abstract
Cyanides/cyanates of sodium or pota ssium not only during centuries but over millenniums were used in methods for extraction the gold from ores, and further in refining of obtained golden m ud. In those processes the cy anides/cyanates still are not changeable. According to the huge amount of tr eated ore, it is expected that the amount of waste treated materials also be huge. We lding and brazing of golden parts frequently are obvious in usage for the purposes of gold jewel making. Therefore, it becomes reasonable that almost of these aggressi ve substances will be appeared in waste water(s). Mass parts of used fluxes and refining substances always are not at the level of golden alloys mass, because golden alloys pos sess high density values. But, the volume parts of used aggressive substances are mu ltiple higher than the volume of a gold jewel. In this paper is discussed the using of la ser welding technology as substitution of using the harmful substances, therefore the amount of waste compounds are markably reduced.
