The mood was apprehensive as data scientists, metallurgists, and engineers from Freeport-McMoRan filed into the control room of a copper-ore concentrating mill in Bagdad, Arizona, on the morning of October 19, 2018. They had come to learn what would happen when they cranked the big mill up to a work rate that had never been tried. The …

Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has …

Now, 1 tonne of REM supplied to the mill contains 0.185 t (185 kg) of neodymium. With 59 tonnes of ore mined per tonne of REM, the amount of ore mined and supplied to the mill to get 1 tonne of neodymium is 59/0.185 = 318.9 tonnes. The mill only recovers 50% of the metal supplied to it. Therefore, for the mill to recover 1 tonne of …

According to Cox and Singer, the average copper ore grade in the mine (x m) was 1.67% around 1990 and in the case of the 25 copper mines analyzed, the average ore grade is 1.48%. These selected mines produced more than 5 million tons in 2009, which corresponded to 32% of the total world production that same year [ 42 ].

Copper occurs in nature in the form of sulphide and oxide ores, salt minerals and as native copper. It is the second most used non-ferrous metal in industry (Boulamanti and Moya, 2016).According to the United States Geological Survey (USGS), the 2019 global annual copper extraction was about 20 million tons (Fig. 1).The highest annual mining …
