Mejoramiento y monitoreo del método de lixiviación de oro y plata por cianuración en la Empresa Mineros del Caribona (Minecar) Gold S.A.S –Montecristo Bolívar.

Abstract

Gold is found naturally in veins and there are different methods for its exploration and extraction, such as amalgamation and cyanidation. In this research, the process of improvement and monitoring of the gold and silver leaching method by cyanidation is carried out in the company Mineros del Caribona (MINECAR) Gold SAS, first the mineralogical and geochemical information is characterized to carry out the leaching process; The material that is extracted from the mine goes to a hopper by means of a winch, from there it goes to the crushing stage where the size of the material is reduced to 1/6 of its initial size, then it goes to the grinding stage that It is carried out in a ball mill, then it is processed in the primary grinding stage to finish reducing its size according to the series of Tyler sieves, from there it is sent to a Hydrocyclone that classifies the material that passes to the flotation stage and the other that goes to the secondary grinding stage, then proceeds with cyanidation and finally with the smelter. The improvement was made from an organization of the teams implementing a jaw pulverizer which ensures the ideal size for grinding, also a control and quality monitoring was carried out in all stages, where gold is leached from auriferous ore with a recovery percentage greater than 95%, the entire process is carried out in a wet way and water recirculation is applied.
