reverse flotation of copper lead:

Copper Lead Concentrate Separation

Mar 19, 2017  Copper Lead Separation Flowsheet A: A bulk copper and lead flotation, followed by a copper depression reverse. This scheme uses cyanide to depress the copper in the reverse process. With the use of cyanide in the reverse, cyanide was also used in the bulk flotation process to depress sphalerite and pyrite.

How to Separate Copper from Lead by Cu Depression

Mar 17, 2017  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.

Oxide and Reverse Flotation SGS

In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting). Aeration is added through spargers at the bottom of the flotation cell. The bubbles attract and then float the waste minerals, leaving the pay minerals in the underflow.
