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

What is Sulfide Mining Mining Action Group

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area and by exposing sulfides to the air and water in our atmosphere sulfuric acid can be created — threatening to poison the nearby water
