• The rate of arsenic release from sulfide minerals can be accelerated by mining activities, which expose the minerals to weathering processes during excavation. Also, arsenic can be mobilized by weathering of outdoor stored waste byproducts produced during the subsequent metal value recovery process.

Conventional process route 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.
The copper minerals are then ground up even finer and purified by another flotation process. The dried copper concentrate of about 28 percent copper is shipped to the smelter. It represents less than one percent of the material removed from the mine.
