The transition to underground mining has enabled 50,000 tpd of conventional crushing, milling and flotation capacity. Copper and magnetite are recovered on behalf of Foskor (a neighbouring mining company) by toll-processing 20,000 Tpd of marginal ore from stockpiles from the open pit operation.
May 15, 2015· Abstract. The Kışladağ gold mine (Uşak, Turkey) has operated since 2006 and is projected to close by 2030, leaving a large open pit. We quantified dewatering requirements during the operational period, predicted pit lake formation during the post-closure period, and assessed the likely impacts on groundwater resources.

Concentrate Thickening & Filtration The concentrate (or concentrates) produced in the facility must usually be dewatered prior to shipment. The first step of the dewatering procedure is usually sedimentation. The design engineer must be extremely careful when developing the size of concentrate thickeners from laboratory data. In the laboratory, concentrates settle extremely rapidly.
