· The mineral barite (barium sulfate), also known as barytes, is most commonly found in hydrothermal veins and as veins in limestone. It is very dense (it has a high specific gravity) and is relatively soft. Those properties make it an excellent weighting agent in drilling muds for petroleum wells. In fact, worldwide, oil and gas drilling account
