Concentration concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill in largescale operations this is accomplished by taking advantage of the different properties of the minerals to be separated these properties can be colour optical sorting density gravity separation magnetic or electric magnetic and electrostatic separation and
Magnetic separation this method of concentration can be applied when the gangue and the ore particles have different magnetic properties for example if the ore particles are magnetic in
Jan 01 2015 ores of this deposit are related to the highgrade type and expected to have a magnetic concentration for iron extraction the main task of magnetic separation is to increase the total iron content in concentrates to a value which allows its further metallurgical processing

Sep 01 2019 an interesting aspect of the magnetic separation of ore s and partially ore i is the enrichment of mn in the magnetic concentrate the amount of mn was increased about 4 times from 04 and 02 in ores s and i respectively to 16 and 08 in the magnetic concentrates the amount of mn in the corresponding tails is more or less zero
Some of the common methodsof ore concentrationare discussed below 1 gravityseparationor hydraulic wash in this method theorehaving high specific gravity is separated from the gangue that has low specific gravity by simply washing with running wateroreis crushed to a finely powdered form and treated with rapidly flowing current of
Dec 22 2020 wolframite is a weakly magnetic mineral and can be separated by magnetic separation wolfram ore coarse concentrate magnetic separation process before separation the material is crushed to3 mm by roll crushers then they are screened into three levels which are 083 3 mm 02 083 mm and 0 02 mm and finally you can get wolframite concentrate by magnetic classification beneficiation
These undesired substances are collectively known as gangue or matrix the process of separating gangue from an ore is known as concentration of the ore it is also called dressing or benefaction metals can be concentrated from their ores using any of these methods hydraulic washing magnetic separation froth floatation or leaching
