Con el presente artículo se busca representar el paso a paso para la obtención de la valoración económica y el agendamiento de un proyecto minero, basado en un yacimiento polimetálico hipotético de Cu y Au, mediante la aplicación de los conceptos de ley equivalente para expresar la presencia de los diferentes metales en términos de un solo mineral, la ley de corte crítica y marginal para definir los límites económicamente viables de minado y la implementación del paquete de software DESWIK

This article seeks to represent the step by step to obtain the economic valuation and the scheduling of a mining project, based on a
hypothetical polymetallic deposit of Cu and Au, by applying the concepts of equivalent law to express the presence of the different metals
in terms of a single mineral, the critical and marginal cut-off grade to define the economically viable limits of mining and the implementation of the DESWIK software package.
