Comparison Of flash flotation and gravity separation …
A few examples involve using both gravity separation and flash flotation processes. Gravity and flash flotation was used in MSV, Chimo, and Eskay Ck mines (Laplante and Dunne, 2002). The flash concentrate is upgraded by gravity separation in these process plants to produce high-grade gold concentrate for direct smelting.
