How to Separate Copper from Lead by Cu Depression

2015-4-16 · To achieve this copper/lead separation, bulk flotation is performed with depressants to control sphalerite and pyrite. Cyanide was used in the bulk rougher as it will also be used in the reverse. Rougher testing indicated that 10 to 50 g/tonne cyanide in the bulk rougher was sufficient. The bulk concentrate was then subjected to relatively high ...

exfoliation | geology | Britannica

exfoliation, separation of successive thin shells, or spalls, from massive rock such as granite or basalt; it is common in regions that have moderate rainfall. The thickness of individual sheet or plate may be from a few millimetres to a few metres.. Some geologists believe that exfoliation results when rocks formed at depth are exposed at the ground surface; the previous
