Process for forming and treating calcium carbonate precipitates

Claim 1

A CONTINUOUS PROCESS OF TREATING SUGAR JUICE WHICH COMPRISES PRELIMING THE JUICE TO REMOVE IMPURITITES REACTING WITH CAO, CLEARIFYING SAID PRELIMED JUICE TO REMOVE SAID REACTED IMPURITIES THEREFROM AS SLUDGE, SUBJECTING SAID CLARIFIED JUICE TO FURTHER PURIFICATION BY MAIN-LIMING AND CARBONATION TO PRODUCE CACO3 SUSPENSION PRECIPITATING OTHER IMPURITIES ALONG WITH CACO3, SEPARATING THE SUSPENDED SOLIDS INCLUDING SAID CACO3 FROM THE CARBONATED JUICE, RECYCLING A FIRST PORTION OF SAID SEPARATED THE AS SEED MATERIAL TO THE CARBONATION TREATMENT STEP AT A RATE SUCH AS TO OBTAIN A SUSPENSION OF ACTIVE CARBONATE IN A RANGE FROM ABOUT 50 TO ABOUT 70 GRAMSS/LITER CONCENTRATION UPON SSUBSTANTIAL COMPLETION OF THE REACTIONS BETWEEN CAO AND CO2, AND RECYCLING A SECOND PORTION OF THE SEPARATED SOLIDS AS SEED MATERIAL TO THE PRELIMING STEP TO BE REMOVED FROM THE PRELIMED JUICE AND FROM THE SYSTEM IN SAID SLUDGE, WHEREBY THE RECYCLE CARBONATE IS MAINTAINED AT HIGH PLURALITY, AND ADAPTED FOR EFFECTIVE SEPARATION FROM THE CARBONATED AND THE PRELIMED JUICE AT SAID CARBONATE CONCENTRATION.
