Through its subsidiary, PT-FI, FCX mines one of the world's largest copper and gold deposits in the Grasberg minerals district in Papua, Indonesia. In addition to copper and gold, PT-FI produces silver. FCX has a percent interest in PT-FI and manages its mining operations. PT-FI's results are consolidated in FCX's financial statements.
Crushed ore from underground is processed through our onsite concentrator, where minerals are separated from the remaining waste rock to produce copper concentrate containing small amounts of gold. Overlooking Ernest Henry Mining operation with the processing facilities in the foreground.
To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls.
The ore is drilled, then blasted to create debris which is then transported to the surface, then on to a mill. An example of a uranium mine schematic from McArthur River, Canada Source: Cameco Corp.'s filing to US Securities & Exchange Commission, March, 2022
ore processing plant which is located about 7 miles from the NorthMet deposit. The plant and associated mining operations were closed in early 2022 due to bankruptcy and at its peak, this plant processed over 90,000 long tons/ day of taconite iron ore via a four stage crushing, grinding and flotation process. PolyMet is now the owner of this plant

06-09-2022 · The final stage will see iron ore containing 12 million tonnes of iron stockpiled in the tailings storage facility. Copper and gold will be recovered from oxide ore that is initially treated as waste.
Problem: A copper ore initially contains % Cu. After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio
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 low-cost project to improve overall mill capacity in June 2022.
16-01-2022 · Silver and gold ore grade (gpt) loaded on pad up 52% and 13% respectively. Average strip ratio (waste to ore) reduced from :1 to :1,due to a one month delay in receiving the ball mill.
Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.
