TWO-STAGE HEAVY MEDIA SEPARATION WITH MEDIA RECYCLING

摘要

PROCESS FOR THE THICK-MEDIUM DYNAMIC SEPARATION OF.MIXTURES OF MATERIALS, SUCH AS MINERALS, HAVING DIFFE-RENT SPECIFIC GRAVITIES,AND INSTALLATION THEREOF.-A B S T R A C T . -This invention relates to a process for the dy-namic separation of mixtures of materials, such as mi-nerals, having different specific gravities, by meansof a thick medium having two different specific gravi-ties, characterized in that the thick medium streamsrecovered at the exit from the separation stage in asingle loop adapted to recycle the thick medium to thefeed end of the separation stage, said circuit beingequipped with means for dividing said thick mediumstreams to said feed end to obtain therein said two dif-ferent initial specific gravities. The invention alsorelates to an installation for performing said process.
