Only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. This method is also used in waste recyling and paper industries.. this method also seperates hydrophobic substances from hydrophilic substances..
Historically, smelting and roasting of ores have been used to capture the gold from difficult to treat ores. Just like those old time miners, we don't want to throw any of the silver or gold away as it can be valuable. Treating high sulfide ore is a difficult proposition, and in the article below I'll take a .

· Concentrating the ore: The ore is crushed, ground and then enriched (concentrated) by Froth Flotation. The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a ing agent which produces a
Usually these sulphide ores are concentrated by forth floatation process. But argentite which is the sulphide ore of silver is preferably concentrated by chemical process of teaching. Now answer the following questions: (i) Explain why instead of float floatation process. Argent (ii) What reagent is use in the chemical leaching of argentite ore?

Question Which one of the following ores is best concentrated by froth floatation method ? (1) Siderite (2) Galena (3) Malachite (4) Magnetite
Aug 18, 2018· (a) Which of the following ores can be concentrated by froth floatation method and why? Fe 2 O 3, ZnS, Al 2 O 3 (b) What is the role of silica in the metallurgy of Copper? Answer: (a) ZnS can be concentrated by froth floatation process because sulphide ores are preferentially wetted by pine oil, whereas gangue particles are wetted by water.
Concentrated coal deposits are clumps of coal located in the Living Rock Caverns beneath the Dwarven Mines. They require level 70 Mining to mine, have a durability of 500, a hardness of 140, and an experience multiplier of There are 8 of these deposits in the caverns. Concentrated coal deposits contain a much larger supply of coal than a normal coal rock, granting five ores at once.
The ore is crushed, ground and then enriched (concentrated) by Froth Flotation. The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a ing agent which produces a kind of bubble bath.

Froth Flotation of Iron Ores Mark Ma CSIRO Process Science and Engineering, Box 312, Clayton, Victoria, 3169, Australia Abstract With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the
"Flotation is a new step in the separation of valuable minerals from gangue. This process has only been in commercial use for about six years. There has been several theories advances as to how the ore is concentrated, and the theory that is now usually accepted is that the oil covers or wets the sulphide mineral particle and does not the gangue; and this mineral particle, by means of induced ...
