PROCESS FOR SEPARATING EARTH AND COAL PRODUCTS CONTAINING EARTH IN A COAL USING THE HEAVY SUSPENSION PROCESS

摘要

THE SUBJECT OF THE PRESENT INVENTION IS A PROCESS FOR SEPARATING FROM EARTH AND CARBON PRODUCTS CONTAINING EARTH IN COAL PAGES USING THE HEAVY SUSPENSION PROCESS. /P P THE PROCESS IS CHARACTERIZED AS CRUSHED OR THE CRUDE MATERIAL IS SORTED, IF NECESSARY, AT A GRANULOMETRY OF 0 TO 50MM, AS FURTHER IS REALIZED IN THE PRESENCE OF A LIQUID PHASE AND FROM THE EXISTING WEIGHTNING MATERIAL OR RETURNED IN THE RAW MATERIAL IN A QUANTITY AT LEAST EQUAL TO 7 BY WEIGHT, PREFERREDLY 10 BY WEIGHT, A MUDDY MIXTURE THE DENSITY OF WHICH IS REGULATED IN CORRESPONDENCE TO THE DEGREE OF SEPARATION, IN SUCH THE MIXED MIXTURE IS THEN PASSED THROUGH ONE OR MORE HYDROCYCLONES 5 AND INTO INSTALLATIONS 6, 7 ENSURING SEPARATION AND OR SORTING ACCORDING TO SIZE, THEN ADJUSTING THE DENSITY OF THE ENTIRE FLOWING SUSPENSION OR OF A PART OF IT IN CORRESPONDENCE TO THE DESIRED DENSITY MUDDY MIXTURE, AND IN THAT THE SUSPENSION IS THEN RECYCLED, THE DENSITY OF WHICH HAS BEEN ADJUSTED, WITH A VIEW TO THE FORMATION OF SLUDGE. /P P THE INVENTION RELATES TO THE FIELD OF COAL.
