In the aftermath of the chemical spill of 4-Methyl Cyclohexane Methanol (MCHM) into the Elk River in West Virginia on January 9, 2014; there are still some who might be unaware of the function of this particular chemical.
According to published documentation under US Patent 4915825 A, 4-Methyl Cyclohexane Methanol was originally invented to increase Coal mineral recovery via the flotation process:
"Flotation is a process for separating finely ground minerals such as coal particles from their associate waste or gangue by means of the affinity of surfaces of these particles for air bubbles, which is a method for concentrating coal particles."
