Potassium isopropylxanthate is widely used as a collector in the froth flotation process for the extraction of sulfide ores, such as copper, lead, and zinc. It enhances the hydrophobicity of the metal sulfide particles, allowing them to attach to air bubbles and separate from the gangue minerals. This compound is particularly effective in the selective recovery of copper and nickel sulfides due to its strong affinity for these metals. Additionally, it is employed in the mining industry for its ability to improve the efficiency and recovery rates of valuable metals from low-grade ores. Its application ensures a cost-effective and environmentally friendly approach to mineral processing.
