Grinding the solid into a powder increases the surface area and increases the rate of the reaction. Heating it would also increase the rate.
Reactions depend on molecular collisions. If a solid reactant is a solid, grinding it into smaller particles will increase the surface area. The more surface area, the faster the molecular collisions, which in turn increases the rate of reaction.
When the surface area is higher, it helps to dissolve it in the solution faster.
One way is to grind up solid, or increase the temperature. Also, you can stir the solution, and then, there are enzymes.
Chemical reactions involving solids work on the surface of the solid. A fine powder has more surface area than big lumps.

By change of state from solid mass to powder through breaking or grinding.
The powdered form of a solid reactant has an aggregate surface area that is many times greater than the solid blockfrom which it came. This makes any reaction proceed faster and more efficiently, usually resulting in enhanced yield as well.

1) melting from solid to liquid; 2) evaporationfrom liquid to vapour;3) sublimation direct from solid to vapour; 4) grinding to make a solid into a powder; 5) dissolving a solid in a solute; 6) freezing from a liquid to a solid.
There are three ways to increase the rate of a chemical reaction. One way is to increase the temperature of the reaction, which increases the rate of molecular collision. Another option is to add a catalyst to the reaction which chemically enables the rate of reaction. Lastly, increase the pressure in the reaction area, which increases the rate of molecular collisions.
Grinding the sample in the recrystallization process will allow for maximum exposure of particles in the original crystal. This will allow a more complete reaction and reformation of crystals that are more pure and stronger than before.

The gold powder is also a solid.
