Copper-nickel mining (also known as "non-ferrous mining") in northern Minnesota is not a new issue for the state. Copper-nickel deposits have been known to exist in northern Minnesota since the 1800s, but it was not until 1948, when deposits were discovered near Duluth, that serious interest in mining these metals developed in the region.
The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in …

Copper-nickel sulfide ore beneficiation methods: The most important is …
1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

The process that starts with mining and carries on through smelting and electrorefining is complex with many process operations. Let's take a closer look at the story of ' liberating copper '. On average, mined ore contains about 1% copper and in order to recover this copper from the rock it requires several physical and chemical processing and ...

Copper- Nickel Ore Flotation Process: A basic principle of copper-sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore. Because it is easier to recovery cooper from the nickel concentrate. The process has a best advantage-get the copper concentrate that has a low nickel rate directly. Cases
