Biomining: metal recovery from ores with microorganismsBiomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from lowgrade ores is the most important industrial appliion and a significant part of world copper production already originates from heap or dump/stockpile bioleaching.

LARCO GMMSAUnderground mining uses a sublevel caving method. Access to the deposit is carried out with horizontal calcareous galleries and spiral ramps. The main phases are the drilling, the charging the drills with explosives and their firing, the collection of the produced ore and the support of the galleries. The produced ore is transported to the surface by electric railroad.
