An improvement in the separation of metallic sulfide mineral ores, particularly those ores bearing copper and molybdenum, in which a mercaptan collector is used in an earlier primary stage, the improvement comprising the addition of activated carbon to achieve deactivation of the mercaptan collector prior to the component mineral separation stage, thereby providing ...read more
· is a method for separating hydrophobic materials which will not mix with water from hydrophilic materials which readily mix with water. Since its discovery, has been a major component for the processing of sulfide-rich …read more
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the recovery and upgrading of sulfide ores". The development of froth flotation has improved the recovery of valuable minerals, such as copperread more
Xanthate, as the collector with strong collection effect, is mainly used to enhance the hydrophobicity of the mineral surface to meet the requirements of .Xanthate is commonly used in the of sulfide minerals. Xanthate is a combination of alcohol, sodium hydroxide and carbon dioxide, which is an anionic collector. . It is light yellow, soluble in water and ...read more
· Froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals …read more
, in mineral treatment and mining, for concentrating the metal-bearing mineral in an ore. Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a on the surface.read more
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic,which is suitable for lead-zinc ore. But the flotation of oxidized lead-zinc ore is a difficult one. In the treatment of lead-zinc oxide ore, it is complicated to choose flotation reagent and process flow.read more
· Froth flotation is a three phase separation process for complex ores Suspended, hydrophobic metal-rich particles are contacted with, and subsequently combine to, air bubbles — whilst the more hydrophilic gangue particles sink and are recovered to the tails stream.read more
