The research presented "Modeling and simulation of adsorption with activated carbon for gold recovery under the Metsim® environment in the Trebol Dorado S.A.C concentrator."; Its objective is to build, model and simulate the process known as gold adsorption with activated carbon through the Metsim engineering program, designing part of our flow diagram and sub-processes such as grinding, classification, preparation of cyanide solution, leaching and the same adsorption, therefore the people in charge compiled the information from the concentrator company to carry out their mathematical modeling, diagram construction and then the simulation of the process. A simulation is taken as a tool for making decisions for improvement in a project that can be carried out and this to significantly reduce the time that spreadsheets take, apart from the fact that the interface is made friendly with the...
