Sequential Copper–Lead–Zinc Flotation

Sequential Copper–Lead–Zinc Flotation

To improve the selectivity between copper and lead, a sequential copper-lead-zinc rougher circuit was tested. Each of the rougher circuits had a dedicated regrind and cleaner circuit. The advantages of the sequential circuits are that the levels of selectivity can be increased, particularly for copper and lead. With this process, copper was recovered first with MBS depression of lead, zinc and .

Material Balance - an overview | ScienceDirect Topics

Material balance was one of the first and is the most widely used technique employed in estimating oil reserves and depletion. Overall estimates of the amount of in-place and recoverable oil are based mainly on material balance. These calculations are also used as a first screening point to determine if sufficient oil remains after waterflooding for application of tertiary recovery.
