Abstract
The present invention provides a process for recovering alkali carbonates such as alkali sesquicarbonates from slurries of minerals such as Trona which contain those carbonates as well as clays and shales. The invention further provides a method for recovering alkaline earth carbonates from caustic slurries of those carbonates, as well as to clarifying the supernatant liquids which result from recovery of the alkaline earth carbonates.
