I have mixture of paraffin wax with Fine coke and graphite dust in bulk. Now i want to extract paraffin wax alone. Could you suggest ways to extract in bulk??

Just a few speculative suggestions. Distillation ?   Or dissolving in a solvent, followed by filtration and distillation ?  Or centrifuge ? 

These are not informed guesses.

You could try hot filtration. You might need a fairly high temperature to bring down the viscosity of the molten wax sufficiently. There are industrial filtration systems that could do this sort of thing, in principle at least. For example, earth treatment of certain grades of lubricating oil is a well-established procedure.

You beat me to it with a better post to boot!  +1

I was just about to say melt the wax and filter. The carbon particles won't be affected by the heat.

Another suggestion is to wash it in a water bath, and allow the wax to settle to the surface, and the coke and graphite to sink. Then skim off the wax.
