M. The Board allocated over eight million euros at the close of rafts Almagrera Mine

The Ministry of Economy, Science Innovation and the Junta de Andalucia has completed the closure of the tailings pond and its integration into the natural environment of the mining wow gold complex Sotiel Crowned-better known as Almagrera-mines, in Calan (Huelva) a performance which has allocated an amount more than eight million euros from EU funds.
According to a note by the Delegation of the Government of the Board in Huelva, the closure of the tailings pond of two phases. The first is what has already been made and includes the execution of perimeter channels to minimize water entry to the raft, as well as filling the gap left by the sterile water from mine tailings and nearby drainage network sludge and pore aion kinah water extraction.
The second phase, pending execution, provides for the realization of a cover layer of the raft to prevent water entry to the mass of sludge.
This mining complex is extracted and processed to produce polymetallic sulfide concentrates of copper, zinc and lead by a classic process of flotation. Pyrite obtained as part of the process undergoes a roasting for the production of sulfuric acid, oleum 20 and copper sulfate pentahydrate.
Processes waste were deposited in two rafts, one of the flotation process, deposit and other sterile-roasting process, deposit of ashes, and closed and which has invested over 17 million euros.
The Company publishes Environmental Management SA (Egmasa), under the Ministry of the Environment, compose and in 2008 the "Project of the closure of the tailings pond and its integration into the wild. Complex Phase I Sotiel Mining Crowned. Ilk ', commissioned by the Ministry of Economy, Innovation and Science through its Provincial Delegation in Huelva.
The objective of this project is the runescape gold decommissioning of the basin that hosted the waste from the flotation process, located one kilometer southeast of the industrial plant within the mine complex Sotiel Crowned.
The actions proposed in the same have been designed to "minimize the impact to the environment once the closure, as both have made their closure actions to dry as the integration into the same."
