Underground Mining
This is the case of resources found underground, when open pit extraction is not possible for either economic or environmental reasons.
Galleries, ventilation (airflow)
Support and fortification
Illumination
Hydraulic transport systems
Open Pit Mining
Mining activities on the surface in contrast with underground mining, are only possible when the deposit emerges on the surface or very small depth.
Concentration (process done by flood)
Leaching (process done with hydrometallurgy)
Non-Metal Mining
It is developed in two different tipes of deposit: natural grains and salt flats. Salt deposits are found in salt lakes where lithium are extracted trough an evaporation process.
Salt flats
Lithium carbonate plant
Excavation / drilling/ construction
Salt viaducts/ aqueducts
