Froth flotation is commonly used to separate many types of metals from their or In this process, ore is crushed, then soaked in a solution that makes the metal in the ore hydrophobic Hydrophobic literally means afraid of water After this occurs, the ore is put in a large vat with soap/detergent and air is flowed through the ore...
History of Sulphide ore flotation dates back to beginning of 20th century Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique This technology has acclaimed importance as a versatile process for...
A common example of this involves froth flotation Froth flotation The ore is first crushed and then treated with something which will bind to the particles of the metal compound that you want and make those particles hydrophobic Hydrophobic literally means water fearing In concentrating copper ores, for example, pine oil is often used...

samples of selenium ores submitted by the Dial Exploration Co from its development work on the We Hope mining claims, in Sandoval County, New Mexico Since many of these ores contain uranium and molybdenum besides selenium, efforts have been made to develop procedures and flowsheets to in-corporate the recovery of these associated metals as well...
metallurgy mĕt`əlûr jē , science and technology of metals metal, chemical element displaying certain properties by which it is normally distinguished from a nonmetal, notably its metallic luster, the capacity to lose electrons and form a positive ion, and the ability to conduct heat and electricity...
Flotation of Free Metal Or Flotation is not generally applied to ores containing a preponderance of values in free metals except for certain well-known exceptions such as the floating of native copper, gold, silver, and free metals having a high degree of luster...
Used as the good collector and frother for the flotation of non-ferrous metal or It has special separation effects on copper lead silver and other polymental zinc sulfide ores and activated zinc sulphide Also used in the flotation of nickel and antimony sulfide ores, specially effective for but also there fractory sulfide nickel ore, mixed ....
The process of procuring metals from ores is called metallurgy and these naturally occurring compounds of metals are known as minerals Metals are usually extracted from the earth by mining Or All ores are minerals, but not all minerals are or Ores are those minerals which contain metals The picture shown above is a gold-bearing ore...
