No, Alchemy Deluxe is not available for iPad 4 mini. However, there are other placements that share the same main functionality you can use instead. For example, there is a game called Alchemy which is actually the same as Alchemy Deluxe. I've searched on the developer's website, but there was nothing mentioned about Alchemy Deluxe regarding compatibility with iOS.
