could you add something like this for platinum ore?

What would be the use case for platinum sorting? The only mod set that I know of that uses platinum is MadClown's with violet metal catalysts, and they add their own sorting recipe for platinum.

this mod uses platinum, but doesnt have any récipe for it

I think it would be best create a new mod for that since the mod author in that instance will eventually put in a platinum recipe. Give me some time, and I'll get a mod together.

Here's the mod: https://mods.factorio.com/mod/Platinum_Sorting
