Melting and solidification are the processes that must occur for a rock to change into igneous rock.
What processes must occur to produce an igneous rock
In order to get an igneous rock from a sedimentary rock, the sedimentary rock must be melted and then that melt must crystallize.

Igneous rocks develops when magma comes through the crust and cools.
To form an igneous rock, you need molten material called magma or lava, which must cool and solidify. This process can occur beneath the Earth's surface (intrusive igneous rocks) or at the surface following a volcanic eruption (extrusive igneous rocks). Additionally, the cooling rate affects the rock's texture; slower cooling results in larger crystals, while rapid cooling produces finer-grained textures.
The process that must occur to change any rock to igneous rock is melting.
What processes must occur to produce an igneous rock
The two processes in the rock cycle that must occur in order to change any rock into an igneous rock are melting (to form magma) and solidification (to form igneous rock). Melting of existing rocks due to high temperatures or pressure creates molten magma, which can then cool and solidify to form new igneous rocks.
erosion
The igneous rock must be broken down into fragments called sediment and somehow cemented together.

a chemical change
Heat and pressure
Energy must be transferred for any change of state to occur. A change of state is the same as a change of phase and there are four states that include liquid, solid, plasma, and gas.
the mineral must melt ok honestly minerals must improve!
A new compound must be obtained.
