Concentration of Ore: Definition, Classification, Methods

Ores found on the earth contains many impurities like sand, rocks, and grit in them, which are collectively known as "Gangue".The concentration of ore is a method of removing gangue particles or other impurities in order to purify the ore. This process is also called Ore-dressing and benefaction.It is a very crucial step to obtain a pure metal from …

Froth Flotation Process

Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

Can magnetic fields be redirected and focused at one point?

The iron confines the field and will guide it to the tip of the cone, where it will emerge with a much higher density and, therefore, a much higher magnetic field strength. This will, of course, reduce the field to the sides of the cone, since this method won't increase the total magnetic field present in the region.
