________ is the process used to concentrate magnetic ores. Options: A . &nbsp Roasting B . &nbsp Magnetic separation C . &nbsp Leaching D . &nbsp Froath floatation

Answer: Option B : B Magnetic separation method is used for concentrating ores that contain impurites that have magnetic properties. Froath floatation process is used to concentrate sulphide ores. Leaching is a process used to concentrate ores that can be dissolved in a chemical solvent. Roasting is the process of converting a sulphide ore to an oxide ore by heating it in the presence of oxygen at higher temperatures. This is generally done after concentation of the ore.
