Ammonium diuranate is then precipitated from the loaded strip solution by raising the pH, and removed by centrifuge. ... CO also developed from commercial graphite and from graphite from the flotation plant. Since it seemed …
The flotation agent helps to form a stable froth of air bubbles, which attach to the mineral particles and cause them to rise to the surface, where they can be collected. The flotation agent works by selectively binding to the surface of the mineral particles, making them hydrophobic (water-repelling).
