Disclosed herein is a method for continuously preparing crystalline cannabinoid particles. The method includes preparing a cannabinoid-rich solution that comprises a first cannabinoid and inducing the cannabinoid-rich solution to a supersaturated state in which the first cannabinoid has a supersaturated concentration that is greater than a corresponding saturation concentration of the first cannabinoid. The method includes flowing the cannabinoid-rich solution into a continuous stirred-tank reactor (CSTR) in a continuous manner, mixing the cannabinoid-rich solution under turbulent mixing conditions to form a plurality of crystalline cannabinoid particles and a cannabinoid-depleted solution within the CSTR, and discharging the plurality of crystalline cannabinoid particles and the cannabinoid-depleted solution from the CSTR in a continuous manner to provide a flow rate through the CSTR. The method includes separating crystalline cannabinoid particles from the plurality of crystalline cannabinoid particles and the cannabinoid-depleted solution in a continuous manner.

The present disclosure is directed to a new and improved separation process that isolates individual minerals from brines containing a mixture of minerals. The brines may be derived from seawater, brackish water, oilfield brines, solution mining, mine run-off, and other sources. Typically, the minerals are recovered as chlorides using a variety of processing steps including evaporation, centrifugation, elutriation, filtration, electrocogulation, crystallization, adsorption, and chromatography.

A process for the production of lithium carbonate from an aqueous salt solution at least containing lithium ions, chloride ions and calcium ions; the aqueous salt solution with a lithium content of at least 0.005% by weight and a maximum 0.2% by weight is condensed in a first evaporation step at a temperature between 40° C. and 160° C. until a concentrate I with a water content of ≤70% by weight and >60% by weight is formed. In a second evaporation step, the concentrate I is evaporated at a temperature between 60° C. and 180° C. until a concentrate II with a water content of ≤60% by weight is formed. In a Li concentration step, the lithium content is raised to at least 0.14% by heating the concentrate II to a temperature of at least 60° C. and thus a lithium-rich concentrate III and a residue III are formed.
