TORONTO (miningweekly.com) – Base metals miner Trevali Mining this week started zinc and lead/silver concentrate production from the metallurgical plant at the Santander mine, in Peru.
The crushing, transfer, grinding (at all four mills), flotation and tailings circuits were all operational and undergoing commissioning and optimisation, the company said in a statement on Thursday.
As part of the commissioning process, the mill was currently processing stockpiled mineralised feed during the day shift, and fine-tuning the plant and optimising the reagent schemes and run criteria following each run, during the subsequent night shift, as required.
Trevali said it currently had 156 945 t of mineralised material grading 4.9% zinc, 1.2% lead, 0.22% copper and 1.5 oz/t silver available for commissioning.
The project team would now aim to ramp up operations to the planned capacity of 2 000 t/d.
