Copper Lead Concentrate Separation - 911 Metallurgist

2015-10-1  At the end, the use of a sequential copper-lead-zinc flotation circuit produced the most efficient copper and lead separation. A bulk flotation process followed by a reverse flotation where copper was depressed and lead was floated from the bulk concentrate also produced separate concentrates, but at lower efficiency than the sequential circuit.
