Reverse Flotation with Flotigam 2835

Clariant's reverse flotation featuring Flotigam 2835-2 removes the silica that cannot be removed by magnetic separation. In this process, the ore slurry navigates through a series of large flotation cells, where air is introduced to create the bubbles for float separation. Flotigam 2835-2 collects and floats the silica.
