· With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the increased amounts of secondary products .
There are also an ambulance, trailers with rescue equipment's and two firefighting vehicles with a capacity of 200 litres firefighting underground. PRODUCTION BOLIDEN GARPENBERG 2018 In 2020, around 3,000 ktonnes of ore were processed to form metal concentrates containing zinc, copper, lead, gold and silver .
For mineral processing project, after blasting, crushing and screening system is always the first stage to reduce the big raw ore lumps to proper small particle size for following mill grinding system. Normally to reduce the big ore lumps to small particles, two to three stages crushing is required.
In Chile, the copper grade of the ores is significantly lower than even that. In 2015, the average copper grade in the ores was only %. For the year 2026, it is expected that the ores in Chile will have copper grades of less than %. This will naturally increase the amount of .

· The processing operation is based on a conventional, wellunderstood model. Two grinding lines, designed for hard ore, will produce highgrade copper concentrate. Each grinding line will include one semiautogenous (SAG) mill and one ball mill, with space for a third line. The mill is initially permitted for a throughput capacity of 127,500 t.
· The world's 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the world's total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The makes the cut, as well, with two mines among the top 20. Copper is expensive to mine and refine.
· Equinor to invest up to in NOAKA project, offshore Norway. By NS Energy Staff Writer 01 Nov 2021. Loed between the Oseberg and Alvheim fields, the NOAKA oil and gas project, which also involves the participation of Aker BP and Lotos Exploration and Production, is expected to see investments of nearly 10bn.
The plant is loed next to the primary P2 shaft and comprises two processing lines. Ore is secondary crushed and then ground in an autogenous grinding (AG) and ball mill circuit. The zinc line has a processing capacity of approximately million tonnes per annum (mtpa) following completion of a lowcost project to improve overall mill capacity in June 2017.
