To enhance the recovery of dense, non-floating botanical remains, we used a siphon subsequent to the normal flotation process. The siphon vacuums the heavy fraction of a flotation sample and retrieves ...

Flotation is a well‐established separation process that utilises the distinct interfacial phenomena between hydrophobic and hydrophilic particles to achieve selective recovery of valuable materials.

Researchers at Aalto University in Finland have developed a new mechanism to process minerals in an environmentally friendlier way compared to current froth flotation mechanisms. In detail, the ...
