In gold ore flotation process, flotation machines are very important, besides, the same important part is the flotation technique and chemicals using, etcs. Gold flotation can recovery smaller size gold than gravity separating. So if your raw gold ore has low grade and smaller size, maybe you can consider use the flotation separating.

In this study, the flotation behaviors of gold and gold-associated sulfide minerals (pyrite and sphalerite) in a polymetallic sulfide gold ore were investigated using flotation kinetics parameters. It was found that high gold recovery (>90%) can be achieved by the selective flotation of pyrite and sphalerite.

1. Introduction. Pyrrhotite predominates among iron sulfides in a number of copper–gold sulfide deposits, and its recovery during the flotation process reduces product quality and causes environmental problems such as iron oxide slag generation and sulfur oxide emissions in the downstream smelting process (Allison and O'Connor, 2011).However, …
