Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses. Therefore, they are generally larger in size and numbers. Cleaner banks are focused on product grade and thus provide low residence time. As such, the number of cells are lower and the cells smaller.

When the scavenger concentrate returns to the FCSMC rougher, the coarse particles are lost to the tailing and then are recovered to concentrate in the cell scavenger, which leads to the coarse particles in circulation all along. However, in FCSMC–cell-2, coarse particles can discharge to the middling in time to decrease the tailing grade.

What is a Free Radical Scavenger? (with pictures)

A free radical scavenger is a vitamin, mineral, or enzyme that is able to destroy free radicals. The term "free radical" refers to a molecule that has one or more unpaired electrons. This makes them very unstable, and they move through the bloodstream, taking electrons from other cells or giving away unpaired ones.
