 — The role of gold beneficiation reagents cannot be underestimated. More than 85% of the world's gold ore is mainly extracted by cyanidation. However, the use of a variety of reagents mixed and …

Diamonds emit light when hit by an x-ray and the resulting light is picked up by a detector. As a mono-layer stream of rocks and diamonds fall through this beam, the detector activates jets of air which knock the diamond into a separate bin (see figure 13). Variations of this principle are used on other mineral systems using lasers.

Rotary Scrubber Working Principle. A high-pressure flushing water pipe is arranged in the longitudinal direction of the cylinder. The rotation of the cylinder screen causes the ore to turn over and collide with each other, and with the hydraulic scouring, the clay is …
