Melted is the past tense and past participle of the verb to melt. For example, we say something melted yesterday, that something has melted in the sun, and that the thing that was left in the sun is melted.

Molten is another participial adjective derived from melt, but in today’s English it is used primarily in reference to melted metals and minerals. And even in reference to these things, melted is often used as the past tense. For example, we might write the molten copper melted yesterday.
