(1) In the case of floatable material.

(2) Because of soluble copper and floatable gangue minerals in the ore, Cu-S bulk flotation technological flowsheet is adopted and obtain good metallurgical performance.

(3) Belt grinder adopted a technology of floatable beam, moreover, belt can be tensioned flexibly and the deviation can be adjusted quickly.

(4) Floatable arch cofferdam is presented to offer dry environment and keep the main function of a reservoir when the dam is strengthening and repairing.

(5) The settling zone portion of the pretreatment system provides for removal of settleable and floatable materials.
