Currently, I work in financial consulting for large companies, some of the global, but recently there was a demand to work with a company in the mining sector, and the company in this sector was one of the market leaders. With that in mind, I sought to go after the main mining companies in the global market so that I could find out and understand how the sector works, so I searched the internet for everything about mining company in addition to talking to experts. And the best way to understand the market would be to evaluate the largest mining companies in the world because the best way to understand something is to look for how the best work.So I made a ranking of the largest mining companies in the world and the ranking was like this: 1 – Glencore PLCRevenue: US$ 178.6 billionNet Income: -US$ 3.2 billionMarket cap: US$30.7 billion Glencore is based in Switzerland and works with metals, minerals, agricultural commodities, and energy. 2 – BHP Group Ltd.Revenue: US$ 42.9 billionNet Income: US$ 8.0 billionMarket cap: $137.2 billion 3 – Rio Tinto PLC Revenue: $41.8 billionNet Income: US$ 7.2 billionMarket cap: $79.8 billion 4 – Jiangxi Copper Co.
