Roasting Ore

Ore roasting can be accomplished in many ways. The simplest way is to build a large wood fire on the ground or in a shallow pit and toss the ore on top. The problems with this are that it is near impossible to guarantee that everything gets well roasted and when you're done you just have a pile of ore and ash that is difficult to separate.
