Mill Needed By Copper Mining

Copper Mining Process | Operations | Minto

The Mill was designed to handle the higher production rates when you are mining open pit deposits. While we are working on plans to potentially start a new open pit in the coming years, we are currently producing 100% of our ore from underground. As a result, we are only operating our Mill about 60% of the time. Our Mill is capable of +4,000tpd of processing capacity so we stockpile ore from

Antamina Copper-Zinc Mine - Mining

Mining is done by conventional truck-and-shovel open-pit methods, with the ore being processed by grinding and flotation. Crushed ore is conveyed through a 2.7km-long tunnel to the concentrator stockpiles. The concentrator has a milling rate of 70,000t/d and is the largest single-circuit SAG-milling operation in the world. The SAG mill provides feed for ball milling to produce flotation feed
