copper flotation process - Xinhai

The flotation process has a relatively simple flow and has the strong adaptability to the change of ore grade. Application: The flotation process is generally used for copper-lead-zinc sulfide ores with simple composition, high raw ore grade, large difference in floatability of useful minerals and coarse disseminated particle size.

Predicting Flotation Recovery

If copper tailing is constant, and it very nearly is for a strictly sulfide copper ore, percent recovery must fluctuate almost directly to the feed assay. The accuracy of a recovery figure is first of all dependent on the accuracy of sampling and assaying. Sampling and assaying errors can become quite significant in the case of low grade ores.
