| EXTRACTION
There are a lot of ways of extracting copper, for example by digging in a mine.But the most effective way is a method called FLOTATION. Flotation is undoubtedly the most important and versatile mineral processing technique Original patented in 1906,flotation has permitted the mining of low grade and complex ore bodies which would have been regarded as uneconomic. PRINCIPLES OF FLOTATION The theory of froth flotation is complex and is not completely understood.Froth flotation utilizes the differences in physics-chemical surface properties of various minerals.After treatment with reagents such differences in surface properties between the minerals within the flotation pulp become apparent and, for flotation to take place, an airbubble must be able to attach itself to a particle, and lift it tothe water surface. |
