Indonesia has also been wooing Tesla, which has been looking to find reliable sources of nickel globally after warning the current cost of batteries remains a hurdle to growth.

Another relevant factor in copper extraction is the specific cost of electricity, strongly driven by the ore grade (lower grades mean higher energy demand). We observe that the effect of decreasing ore grades on specific energy costs can be offset by deploying highly solar power systems.

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.

Grasberg hosts one of the biggest copper and gold deposits in the world. The Grasberg mine is owned and operated by PT Freeport Indonesia (PT-FI), which is a joint venture between Freeport-McMoRan (48.8%) and PT Indonesia Asahan Aluminum (51.2%). It produced 1.22 billion pounds of copper and 2.6 million ounces (Moz) of gold in 2018.

A global copper mine-by-mine review undertaken by ICSG found that the global average copper ore grade was as low as 0.45% copper in reported reserves and only 0.65% copper in 2015 copper mine production. Global weighted average of copper concentrate output in a large sample of plants was around 25% copper in 2015 data.

Construction cost was $175 million, $55 million above the original budget. A 116 km road and pipeline, port, airstrip, power plant and a new town called Tembagapura (literally: copper town) were built. It officially opened in 1973 (although the first ore shipment was in December 1972), and was expanded by Ertsberg East, which opened in 1981.

The largest copper mine in North America (and the world's largest man-made excavation) is the Bingham Canyon Mine near Salt Lake City, Utah. A $1.5 billion modernization program completed in 1998 turned Bingham Canyon into North America's lowest-cost copper producer, a model of operational efficiency and environmental compliance.

copper from oxide ore by placing the crushed ore on a pad in a heap and spraying the leaching solution, sulphuric acid, over the heap. The acid trickles through the heap and dissolves the copper mineral into solution. The leach solution collects at the bottom of the pad in a collection pond. It is then piped to a SX-EW plant where first, the ...

These costs are based on the following assumptions. For the 2×1 SX plant the capital cost was obtained by averaging the capital costs for the 3 SX plants with PLS flows of 1820 m³/h in Table 1, then dividing by 2 and multiplying by 1.1 since the costs at ½ scale should be about 10% greater on a unit flow basis.

increased copper/iron selectivity and lower viscosity than LIX 6410. These improved reagent properties broadened the range of copper leach liquors which could be successfully treated by solvent extraction, for less staging thereby reducing the capital cost of the SX plant, and lowered operating costs by decreasing organic losses and tankhouse ...
