What is the name of the process used for the concentration of sulfide ores?

💡 Solution & Explanation

The froth floatation method is widely employed to concentrate hydrophobic sulfide ores by mixing finely ground ore with water and collectors, causing the mineral particles to rise in a froth while gangue impurities remain behind. Magnetic separation is utilized for ferromagnetic ores like magnetite, whereas leaching involves chemical dissolution of target minerals. This metallurgical technique forms an essential initial step in extracting metals like copper, zinc, and lead from their native sulfides.
