(DOI: 10.1007/BF03402398) The utility of yeast, Saccharomyces cerevisiae, in the separation of quartz from hematite is demonstrated. Yeast cells, as well as their metabolites, functioned as flotation collectors, depressants or flocculants and dispersants for hematite and quartz. Interaction between yeast and the above minerals resulted in significant surface …

This product is then fed to the cleaner cells. For cleaner flotation, column-type flotation cells that produce smaller bubbles than mechanical flotation units are frequently used [54,55]. By using smaller bubbles, the collision efficiency of particles and bubbles increases, resulting in higher copper recovery for fines in column flotation.

Rubies are red due to traces of chromium in the corundum. All other colors of transparent corundum are called sapphires. Deep blue sapphires are blue due to the presence of titanium and iron. Synthetic corundum was first created in 1837 and in 1903 the manufacture of corundum became more large scale.
