A process for recovering lithium phosphate and lithium sulfate from a lithium-bearing solution, such as a brine or pregnant process liquor is described. The process includes adding phosphate to the lithium-bearing solution to precipitate lithium phosphate and then separating the resulting lithium phosphate precipitate from the solution. The separated lithium phosphate precipitate is then digested in sulphuric acid to produce a digestion mixture from which a lithium sulfate precipitate is separated. An alkali metal hydroxide is added to the separated solution to produce an alkali metal phosphate solution and this is recycled for use as phosphate in the first step of the process.

A method of making a proppant-gel matrix comprising: a) hydrating a gelling agent to form a hydrated gelling agent; b) adding a basic compound to the hydrated gelling agent to form a basic hydrated gelling agent having a pH in the range of 11.5 to 14.0; c) mixing the basic hydrated gelling agent and a proppant to form a basic hydrated gelling system; and d) adding a crosslinking agent to the basic hydrated gelling system to form the proppant-gel matrix, is disclosed. The proppant-gel matrix can then be used as a fracturing fluid in a hydraulic fracturing process.

The present invention relates to a method for producing lithium phosphate, comprising: passing a lithium-containing solution through an aluminum-based adsorbent to adsorb lithium on the aluminum-based adsorbent, passing the distilled water or an aqueous solution having a lower lithium concentration than the lithium-containing solution through the aluminum-based adsorbent on which the lithium is adsorbed to obtain a lithium-containing desorption solution, and putting a phosphorous supplying material in the lithium-containing desorption solution to obtain lithium phosphate

An aqueous organ preservation solution includes taurine and L-alanine-L-glutamine and glutamic acid. The organ preservation composition can be stored in a solid state, for example in the form of small particles (e.g. a powder or micronized powder), and be dissolved in water, thereby instantly providing a ready-to-use organ preservation solution.
