Atlantic Nickel extends Santa Rita mine life to 34 years

Since open-pit operations restarted in August 2019, the mine has produced 48,000 tonnes of nickel concentrate. (Mirabela put the mine on care and maintenance due to low nickel prices in 2015.) Mining from the open pit is scheduled to last eight years, ending in 2028. It will then transition to an underground mining operation, extending the life

Nickel Mining and Processing: Everything you Need to

The Nickel Mining Process. Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well-known purification processes is called the Mond Process, which is an extracting and

Reading: Open-Pit Mining Geology Lumen Learning

Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining. Open-pit mines are used when deposits of commercially useful minerals or rocks are found near the surface; that is
