ABSTRACT:
Froth Flotation method of separation of sodium compounds, principally nahcolite, dawsonite, trona, related authigenic sodium ores, and corresponding sodium compounds including sodium carbonate and sodium bicarboate, from kerogen-type organics-containing rock, by use of sodium carbonate and/or sodium bicarbonate-containing brines having a basic pH ranging above about 7.0, preferably 8.0 - 12.0, and recovering a sodium compounds-rich fraction as a non-float portion, and an organics-rich fraction as a float portion. Frothers, froth control agents and collection agents may be used separately or in combination. Single or multiple-stage flotation, with cleaning, conditioning, scavenging, reflotation, and combining of products may be used. Feed ore and products may be screened to upgrade the head or product assay. By this method, raw or retorted oil shale may be separated from sodium minerals or compounds contained therein.
