Currently, the city of Cerro de Pasco is officially in emergency due to the high level of contamination of its natural resources caused by the open pit mine that exists in the middle of the city and something more dangerous, air pollution by waste toxic substances that pile up inside and around the city. In this sense, this research proposes and develops the detection of the percentage of lead sulfide and zinc oxide, scattered in the city, using the digital processing of multispectral satellite images. As a result of this mineral detection, it is obtained that more than a quarter of the area of the city, it contains minerals scattered in urban areas.
