BOLIDEN SAYS TO REOPEN AZNALCOLLAR ON TUESDAY
The mine, which produces around 125,000 tonnes of zinc and 2.9 million ounces of silver per year, will gradually reincorporate workers and should be back at full production by June, a spokesman told Reuters.
The residue pool at the mine burst in late April 1998 sending a toxic wave into Donana national park, one of Europe's largest nature reserves. The spill caused damage over an area of around 30-kilometres, destroying rare plant and wildlife.
The spokesman said, however, that it was "physically impossible" for the accident to be repeated as a former open-cast mine was now being used for a residue pool.
The clean-up operation has so far cost more than $100 million, and is still not fully complete.
Although a judicial enquiry has yet to decide who was responsible for the accident, Boliden says it was due to an earth slide near the bedrock of the waste pool, around five feet (14 metres) from the surface.
