froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.the first successful commercial flotation process for mineral sulphides was douglas gold medal in for his contributions to the field of flotation.the particle sizes are typically less than .mm µm but sometimes
in ore beneficiation, flotation is a process in which valuable minerals are the particle size to which the ore is ground depends on the nature of the ore.many factors influence the amount of reagent required for a particular application.gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even
