In Idle Heroes, the Altar is used for disassembling Heroes you no longer want to keep.
Heroes will be disassembled into 
Soul Stone Shards, 
Hero Promotion Stones and 
Spirits.
Disassembling 1
and 2 Heroes doesn’t give you Soul Stone Shards but there is no reason to keep them so just disassembling them right away after having a 3+ team.
You will also get back all of the resources you used before on the disassembled Heroes, except Gold, containing Spirits, Hero Promotion Stones and 
Magic Dust.
Gears and Artifacts will also get returned to your Inventory.
You can also easily see what you will get after the disassembly by choosing those Heroes and then tap on the magnifier icon.
