A bedded barite that has thinly bedded shale, chert, or argillite also is mined and hauled directly to the processing plant with very little waste separation. If the bedded or vein barite zone is pure enough and of sufficient size, the ore zone may then be mined to produce barite that will meet specifications without further processing.
