High Pressure New Arrival Copper Ore Processing Ball Mill In Canada

Dec 03, 2020 Copper Mountain Mining has released a new life-of-mine (LoM) plan for the Copper Mountain mine located in southern British Columbia, Canada. The new LoM plan includes a proposed mill expansion to 65,000 tonnes per day (t/d). Estimated to be 21 years, the new mine life also includes three years of processing stockpiled ore

May 29, 2020 It is a combination of improved technology, reduced fine grind requirements and maintenance benefits that led to Los Andes Copper replacing the SAG and ball mill crushing circuit proposed in its Vizcachitas copper-molybdenum project preliminary economic assessment (PEA), with a three-stage crushing circuit that uses high pressure grinding roll (HPGR) technology in the tertiary

Extract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 15-20 per cent of the world’s current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation

Microscopic analysis has found values of 75 to 95% for copper minerals liberated from sulfide ores, depending on the operating pressure value. Copper recovery in downstream flotation varies from 80 to 85%, while the same value for ore that has been conventionally crushed (i.e. without using of high-pressure technology) is 80%

The processing plant is expected to treat ore at a nominal rate of 150,000tpd of sulphide ore to produce copper concentrate. Ore from the open-pit will undergo three stages of crushing, including primary, secondary, and tertiary. The tertiary crushing unit will employ high-pressure grind rolls (HPGR) to crush the ore
