Froth Flotation Circuit Design And Basic Testwork Requirements
Cleaner flotation tailings is an intermediate product and is recycled within the flotation circuit. Many ores contain multiple valuable minerals that can be floated into separate concentrates. Examples would include a lead-zinc ore, in which the lead and zinc minerals are recovered sequentially into separate concentrates.
