  Rezumat:  The main objective of the present paper is to present a system of mineral production by environmental sound processes. One of the main challenges for the important mineral producers in the world is the environmental protection and workers safety and health. Manto Verde deposit belongs to the IOGC category (iron oxide-copper-gold), a relatively recently described group of ore deposits, among which the most famous are Olympic Dam – Australia, and Candelaria – Chile. Manto Verde is a middle-sized and middle-grade Cu deposit with a low content of Au. There are several environmental actions that the mining company implemented, in order to comply with the environmental protection regulations: - diminishing the surfaces covered by the ore stocks during the primary processing; - diminishing the infiltration of liquid contaminants by installing impermeable liners; - diminishing the air pollution by moistening the ore during the crushing operations, SO2 capture and sulfuric acid production.

Keywords: IOGC ore deposits, environmentally sound mining, contaminants, air pollution
