Four Major Flotation Separation Processes to Separate ...

2021-2-1 · Chalcopyrite is a widely distributed copper-iron sulfide mineral, often containing trace amounts of gold, silver and other minerals, and is the main copper-containing mineral. With the deepening of mining, low grade polymetallic refractory chalcopyrite has become an important source of copper ore. Now, let’s know the common chalcopyrite flotation processes together.
