Abstract The use of higher plant cell cultures for the production of recombinant proteins, including medical ones, seems to be a promising alternative to existing platforms based on mammalian or bacterial cells. Undoubted advantages of plant cells include the following: no risk of contamination with viruses and prions of animal …

Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
