Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
110 words
IN A PROCESS FOR MAKING CARBONATE-BONDED ORE AGGLOMERATES IN WHICH ORE FINES ARE MIXED WITH WATER AND A MATERIAL SELECTED FROM THE GROUP WHICH CONSISTS OF CALCIUM OXIDE, CALCIUM HYDROXIDE, MAGNESIUM OXIDE, MAGNESIUM HYDROXIDE, AND COMBINATIONS THEREOF, THE RESULTING MIXTURE IS FORMED INTO GREEN AGGLOMERATES, AND THE GREEN AGGLOMERATES ARE TREATED WITH CO2 TO CONVERT SAID MATERIAL INTO A CARBONATE, THE STEP WHICH COMPRISES INTRODUCING TO THE MIXTURE A SUBSTANCE SLEECTED FROM THE GROUP WHICH CONSISTS OF SODIUM TETRABORATE AND AMMONIUM BORATE, WHEREBY AN INCREASE IS EFFECTED BOTH IN THE SOLUBILITY OF CO2 IN THE WATER AND IN THE MAXIMUM WATER CONTENT WHICH CAN BE TOLERATED IN THE GREEN AGGLOMERATES.
