Salt mixed with water (ice) creates a dissolved mixture which has a lower melting point (like ocean water) and therefore, will cause ice to melt. But technically, the new solution is not water (ice), only dissolved salt in water, so ice alone cannot be melted without heat.

The truth is that it is heat is what ultimately melts the ice whether that heat is generated by flame, radiation (sunlight) or chemically (salt, calcium chloride)

Phase changes all fundamentally involve heat. Practically, the relevant thermodynamic variables are temperature and pressure.
