· Calcined dolomite is also known as dolime or doloma. When dolomite is heated at a high temperature then it loses its reactivity and the product is known as burnt dolomite. Burnt dolomite is a refractory material and is used in the manufacture of basic refractories. Various uses of lime and dolomitic lime in the steel plant include its use in
