In South Australia there are a number of limestone occurrences which have been worked for long periods, and a high tonnage of limestones fines has accumulated. These fines are of too low a grade to be used. The Department of Mines (SADM) requested of Amdel that an investigation be made into the beneficiation of limestone fines produced from the Angaston, Klein Point and Rapid Bay quarrying operations, the aim being to upgrade these materials to contain at least 95% CaCO3. A testing programme was devised by Amdel for achieving this, involving screening, flotation and magnetic separation. Other work undertaken entailed mineralogical examination and spectrochemical analysis of samples of fines material. From initial testwork it was found that limestone fines from Angaston, containing 91% CaCO3, could be upgraded by flotation to a concentrate containing 96.7% CaCO3, 1.05% MgCO3 and 1.32% Fe2O3. The recovery of calcium carbonate was 83.2%. By single stage cleaning, a concentrate containing 95.0% CaCO3 was produced with a recovery of 93.6% of the calcium carbonate. In subsequent testwork, limestone fines from Rapid Bay containing 81.1% CaCO3 were only slightly upgraded by screening. Separation of the raw sample at 100 mesh gave a product containing 83.2% CaCO3 with a recovery of 82.1%. Flotation tests showed that a concentrate containing 87.2% CaCO3 could be produced with a recovery of 97.2% of the calcium carbonate. The MgCO3 content of screened and flotation products was 7.3% and 7.7% respectively. Attriting tests made on lump samples using a tumbling mill and a Denver attritor did not improve the grade significantly.
