Abstract: Processes and systems for isolating manganese (Mn), cobalt (Co), nickel (Ni) as a purified co-precipitated product or alternatively independent products, from a lithium-ion battery waste stream like black mass are provided. The process may include processing black mass in an extraction process that comprises mixing the black mass with a source of iron (III) ions and a source of iron (II) ions in an aqueous liquid to extract Mn, Ni, and Co and the at least one impurity element to form a stream, then filtering solids including the graphite and iron hydroxide from the stream that then comprises Mn, Ni, and Co and at least one impurity element. The stream may be further purified by removing the at least one impurity element and Mn, Ni, and Co can be separated from the stream to form one or more recovered products comprising one or more of Mn, Ni, and C0.

Abstract: A method for in situ solution mining of a mineral from an underground evaporite stratum using a set of wells in fluid communication with at least one mineral cavity with some wells operated in solvent injection mode and other wells operated in brine production mode and optionally with some inactive wells, comprising switching the operation mode of one or more wells. The evaporite mineral preferably comprises trona. The at least one cavity may be formed by directionally drilled uncased boreholes or by lithological displacement of the evaporite stratum at a weak interface with an underlying insoluble stratum by application of a lifting hydraulic pressure to create an interfacial gap. The extracted brine can be processed to make valuable products such as soda ash and/or any derivatives thereof. This method can provide more uniform dissolution of mineral in the cavity, minimize flow channeling, minimize sodium bicarbonate blinding for solution mining of incongruent trona ore, and/or may avoid uneven deposit of insolubles.

Abstract: Methods to recover or separate cesium formate or rubidium formate or both from a mixed alkali metal formate blend are described. One method involves adding cesium sulfate or rubidium sulfate to the mixed alkali metal formate blend in order to preferentially precipitate potassium sulfate from the mixed alkali metal formate blend. Another method involves adding cesium carbonate or cesium bicarbonate or both to preferentially precipitate potassium carbonate/bicarbonate and/or other non-cesium or non-rubidium metals from the mixed alkali metal blend. Further optional steps are also described. Still one other method involves converting cesium sulfate to cesium hydroxide.

Abstract: Methods for recovering gold from gold-bearing materials are provided. The methods rely upon on the self-assembly of KAuBr4 and α-cyclodextrin (α-CD) in aqueous solution to form a co-precipitate, a 1:2 complex, KAuBr4•(α-CD)2 (“α•Br”), either alone or in an extended {[K(OH2)6][AuBr4]⊂(α-CD)2}n chain superstructure (FIG. 1). The co-precipitation of α•Br is selective for gold, even in the presence of other metals, including other square-planar noble metals. The method enables one to isolate gold from gold-bearing materials from diverse sources, as further described.
