How to get legendary everything with the maximum efficiency
The same platform gives iron, carbon+sulfur and calcite which leads to coal and stone. Recycling iron ore to legendary takes a lot of recyclers and you'd need to repeat that for coal and stone. I found building the platform to be significantly easier than recycling the ores, the fact I'd be dusting resources not even a consideration to me.

Iron Ore
Iron ore is a mineral block found underground. It is a source of raw iron, which can be smelted into iron ingots. Deepslate iron ore is a variant of iron ore that may generate in deepslate and tuff blobs. Iron ore itself can be obtained by mining it with a stone pickaxe or higher enchanted with Silk Touch. When mined without Silk Touch, iron ore drops raw iron. It is affected by the …
