(C) The concentration of ore (also known as beneficiation or dressing) involves removing gangue from the ore. The common methods are:$(i)$ Hydraulic Washing (Gravity separation)$(ii)$ Froth Flotation$(iii)$ Magnetic Separation$(iv)$ LeachingLiquation $(A)$ is a method used for the refining of metals with low melting points.Electrolysis $(C)$ is a method used for the refining of metals.Therefore,the methods $NOT$ involved in the concentration of ore are $A$ (Liquation) and $C$ (Electrolysis).

The methods $NOT$ involved in the concentration of ore are:
$A$. Liquation
$B$. Leaching
$C$. Electrolysis
$D$. Hydraulic washing
