Methyl Isobutyl Carbinol (MIBC)
CAS Number: 108-11-2
Methyl Isobutyl Carbinol (MIBC) is the most widely used synthetic flotation frother in the mineral processing industry, valued for producing thin-walled, fast-breaking bubbles with excellent selectivity. It generates a low-viscosity froth that breaks easily, minimizing entrainment of gangue minerals and water, resulting in higher concentrate grades. MIBC is used across all major metallic ore flotation circuits including copper, gold, lead-zinc, and molybdenum.
