Evaluación de diferentes reactivos aplicados en la precipitación del oro

In the present research work, 4 different reagents used in the precipitation of gold from solutions are evaluated, two of them used in a classical way such as sodium bisulfite and ferrous sulfate, against two rare species such as sugar and starch. In the experimental part, alluvial gold was mixed with sandy river material to assess the efficiency of the reagents, the leaching of the gold was carried out with aqua regia, this being a particularly strong oxidizing agent formed by the mixture of nitric acid and hydrochloric acid In a 3: 1 volume ratio respectively, statistical programming software was applied in the data analysis, with sugar being the highest precipitating agent.
