Define all the processes of concentration of ore.
Answers
Answer:
For a sulphate ore it has to be roasted that is heated and the reduced to remove all tge gangue from the ore .
For a carbonate ore, calcination that is heating with limited supply of oxygen and the reduction must be done to purify the ore and extract the metal from it .

PLZ MARK MY ANSWER AS BRAINLIEST PLZ !!
Answer:
1)Hydraulic washing
This methodology is predicated on the variations in weight between the gangue and also the metal. Generally, the metal particles of the ore are heavier than the impurities. thus we have a tendency to use the principle of gravity separation to separate the 2.
2)Magnetic Separation
Just like we have a tendency to saw earlier, the physical properties of metals will enable us to separate them from the gangue. One such property is magnetic properties of metals. during this methodology of Magnetic Separation, we have a tendency to use the magnetic properties of sure metals to divide them from the non-magnetic gangue.
3)Leaching
Leaching may be a action of concentration of ore. Here the ore dissolves in an exceedingly chemical resolution. The minerals can react and dissolve jilting the impurities solely that strain. then the metal are going to be obtained from the chemical resolution. allow us to currently take a glance at an example of however we have a tendency to get metal by action.
4)Bayer method
The action of metal from its core mineral on an industrial scale is understood because the bayer process. This method can provide us the tip product of corundum (aluminium oxide) from mineral. the opposite impurities of oxide, titanium dioxide and varies alternative oxides can separate.
