Question

In the Wilfley table method, the particles of gangue are
separated by
separation method.
(A)
Magnetic
Froth floatation
(C)
Hydraulic
Gravitational​

Answer 1

Wifley table method is gravitational  seperation method

Explanation:

• Wifley table also called gold concentrating table was first built on may, 1895.

• The first full size table was built by  Mr . A.R. Wifley and was used in his own mill in kokomo colo, in may 1869.

• It is a sand table that seprates heavy mineral particles from lighter gangue by means of longitudinal riffles impending the downward flow and a horizontal reciprocating motion carrying the heavy particles off the end of the table.

Answer 2

In the Wilfley table method, the particles of gangue are separated by gravitational separation method.

Option (D) is correct.

Explanation:

• In the Wilfley table method, the particles of gangue are separated by gravitational separation method.
• This method is used to separate the ores form the lighter particles.
• The lighter particles are washed away with water and heavier particles are left behind.
• This method is performed on the wilfley table to separate the heavier particles from the lighter ones.
• Oxides of iron and tin are separated by this method.
