The first one processes the material for manufacture the silicon metal and ferroalloys and the second line process the material that does not meet the chemical specifications or appropriate particle size and is used in the local industry as aggregates. Transactions in the treatment plant are: prescreening, grinding, washing, sorting according to size by sieves and according to quality through optical system in the plant selection called Mikrosort.
