The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit.
Our goal was to develop a practical process flowsheet and define process operating parameters and metal recoveries to the required level of detail and accuracy. This included developing process design criteria, equipment requirements, and process capital and operating costs. ... Grinding circuit improvements, Granny Smith gold mine, Australia ...
Flowsheet selection for freemilling ores can be relatively straightforward, with the key issues revolving around comminution circuit selection, the use of heap leaching, treatment of highsilver ores, and flotation options for freemilling sulfides.
