Low grade dumped limestone sample having high silica of 81%, 368% CaO, and 3% Al 2 O 3 has been studied with the aim to reduce the silica level to below 3% for its utilization in iron making Beneficiation study of the sample was initiated with des of the feed sample of −100 µm to remove the siliceous ultrafine particles and to with CaO of the limestone form the main ingredients that make up the cement but shoul limits It is apparent that this siliceous limestone sample for cement industries as the content in this(PDF) Geochemical assessment of a siliceous limestone
LIMESTONE DEPOSITS VS BENEFICIATION JOHN A AMES Alpha Portland Cement Company, Easton, Pennsylvania ABSTRACT Limestone for portland cement must be beneficiated to produce uniform raw material for the kiln Careful quarrying and selective recovery are factors in this process, but the chief aspects of beneficiation are "in plant" In the South African limestone and dolomite industry, there are currently 24 producers and 43 quarries Eleven limestone producers supply 80% of the South African market Dolomite and limestone are used commercially in unprocessed, ground, airseparated, precipitated and calcined forms Cementitious products are derived from a blend of limestone,REVIEW OF THE DOLOMITE AND LIMESTONE INDUSTRY IN SOUTH AFRICA
