History of Sonia

Sonia mine has been in operation since November 1963, when the mining permits were issued. In 1996 joined Ferroatlántica Group, formerly belonging to Corporación Noroeste.

The site of metallurgical quartz Sonia mine is philonian type and hydrothermal origin.

Description of the mining operation

The operating method used in mine consists in clearing coating materials from the roof of the vein located, to allow access to quartz. The quartz mineral extraction is done by drilling and blasting, loading the material flown with backhoe and transported by miner dumpers to the treatment plant.

The treatment plant consists of two lines. The first one processes the material for the manufacture of silicon metal and ferroalloys, and the second line processes the material that does not comply with the chemical specifications or appropriate particle size and it is used in the local industry as aggregates.
