The present work of Investigation, it was based on a reaction of combustion using a calorimeter type bomb to separate Gold of a concentrate with activated coal. The aim is to determine the accuracy and precision of the method of combustion in the bomb calorimetric after the process of cianuración, absorption with activated coal and his later quantification for atomic absorption, demonstrating so by this method the major recovery of Gold is obtained. For the fulfillment of our aims, it was necessary to work with golden boss's diverse standards which were injected to a gram of coal approximately, and one took to combustion the sample. After obtained the sample combustion totally, the residues that stay remove to digestar using royal water, we dilute with nitric acid 1 % for his later reading in the equipment of Atomic Absorption and to obtain the golden concentration. The experimental pro...
