What is s11d mine?

S11D is a mega iron ore mine located in the state of Pará, Brazil, which began operations in December 2016. The mine is owned by Vale, one of the largest mining companies in the world, and is estimated to hold 4.8 billion tons of iron ore reserves. S11D is the largest mining project that Vale has ever undertaken and is expected to produce 90 million tons of iron ore per year at full capacity. The mine has one of the lowest operating costs in the world due to its use of autonomous trucks and trains, which require fewer workers. The project has also been designed to minimize environmental impact, with the use of natural drainage and the protection of local fauna and flora. S11D has created many job opportunities in the region and has contributed significantly to the Brazilian economy.
