Limestone (Industrial) Refer also Dolomite (Industrial)
The limestone is extracted by ripping and dozing, although some blasting of hard bands is required. The material is blended, hammer milled to -25 mm and shipped daily to Birkenhead in a purpose-built bulk carrier, the Accolade II. Caroline. Sibelco Ltd has been working the Caroline limestone deposit, 25 km southeast of Mount Gambier, since 1979.
