Esta investigación tiene por objeto dar a conocer métodos científicos-experimentales, para evaluar correctamente reactivos de flotación usados en concentración de minerales. Se presentan las variables, ecuaciones matemáticas, metodología y otros parámetros importantes que permitirán cuantificar eficientemente en cualquier planta de beneficio minero-metalúrgico, la calidad de los reactivos en proceso de evaluación.

The purpose of this research is to present scientific-experimental methods to correctly evaluate flotation reagents used in mineral concentration. The variables, mathematical equations, methodology and other important parameters that will efficiently quantify the quality of the reagents under evaluation are presented in any mining-metallurgical beneficiation plant.

Column flotation is particularly attractive for applications involving multiple cleaning stages in conventional cells and for complex minerals that have selectivity problems, substantially raising the grade of the concentrate (2-4%) and higher recovery (2-3%) , with a single cleaning stage, this equipment adapting very well to computer control. Its acceptance in the mining industry is increasing due to multiple advantages including lower cost of installation and operation, less space occupation, substantial decrease in energy consumption, mainly because it does not have a mechanical agitation system, and less consumption of reagents.

The need arises to take advantage of the best way to increase the added value of our mining products, specifically concentrates containing precious metals, to obtain maximum economic benefit. A method is formulated to determine optimal conditions for leaching concentrates. This method is fundamentally based on cyaniding gold concentrates that respond efficiently to this process, then developing alternatives for the recovery of Au and Ag from pregnant solutions, using the known methods of carbon in pulp and merrill crowe or another that consists of selectively precipitating silver with sodium sulfide and from the remaining solution, recover the gold with activated carbon, efficiently obtaining high quality separate products.
