In the case of the Zn and Pb mining facility, the elaboration of
the hazardouswaste management planwas found to be more difficult,
mainly because of the geographical isolation of the mine.
So, it was first recommended to replace hazardous raw materials
when possible. Moreover, the separation of all the waste
streams for possible waste reuse was implemented in the mine.
Finally, the most important measure was the beginning of the
technical study for using spent oils in the mining facility as raw
material for the production of the explosives (used as first step in
metals recovery from the rock). For this purpose, and to storage
hazardous wastes in the facility, it was recommended that the
plant should obtain the respective environmental permissions as
a hazardous waste elimination facility.
