Points 3 is a little off the mark. Bulk flotation is where a group of floatable minerals are targets together for maximum recovery whereas selective (or differential) flotation they are targeted sequentially with one of the minerals being depressed while the other floated. Usually when they are floated sequentially grade is of a concern.
