Compositions and methods are provided that provide recovery of metals such as copper, nickel, cobalt, indium, and other metals are recovered from mine tailings, in situ ore bodies, or postconsumer waste. An amine-containing lixiviant is utilized to generate an aqueous solution of the desired metal from insoluble salts present in the source material. Metals can be recovered and further purified by various processes, including extraction into an immiscible organic solvent, electrowinning, crystallization, and chemical reduction. Spent lixiviant can be regenerated and recycled back into the metal recovery process.

Methods for recovering copper, cobalt, indium and nickel with amine containing lixiviant

A method for generating metal peroxides from metal-containing raw materials is provided. The raw material is initially treated with a lixiviant salt, generating a soluble metal salt and a lixiviant base. Subsequent application of a peroxide or a source of peroxide generates the metal peroxide and also regenerates the lixiviant salt. This regenerated lixiviant salt can be recycled for application to additional raw material. Both stepwise and continuous processes are described.

Compositions and methods for production of metal peroxides

Compositions and methods for treating waste water produced by copper mining operations are described herein. Slag from steel making operations and other industrial waste materials that include alkali metal and/or alkaline earth elements have been found to both raise pH of the waste water and also reduce arsenic content. Following such treatment the spent slag or industrial waste can be utilized as a source of valuable metals or incorporated into stabilized building materials.

Compositions and methods for treatment of mine tailings

This present disclosure provides a vessel assembly for use in temperature sensitive shipping that can maintain a payload temperature across a range of temperatures. Importantly, the vessel assembly of the present disclosure reduces the overall packaging materials used in a shipper box and prevents the 'wrong' mixture of PCM-containing vessels from being used.

Vessel assemblies for temperature control

Hydrometallurgical systems, methods, and compositions are described in which amine-based lixiviants are utilized in substoichiometric amounts to recover alkaline earths from raw or waste materials. The lixiviant can be regenerated and recycled for use in subsequent iterations of the process or returned to a reactor in a continuous process. Extraction of the alkaline earth from the raw material and precipitation of the extracted alkaline earth is performed in the same reactor and essentially simultaneously.

Systems and methods for alkaline earth production

The present disclosure provides composites comprising an open cell foam and a small pore area material, methods for their preparation, articles of manufacture comprising them and methods for preparing the same.

Template-assisted production of porous materials

Hydrometallurgical systems, methods, and compositions are described in which organic amine-based lixiviants are utilized in the selective recovery of alkaline earth elements. The lixiviant can be regenerated and recycled for use in subsequent iterations of the process. Suitable lixiviant species include zwitterions, including zwitterion pairs that act as counterions to one another.

Making mineral salts from various sources

Hydrometallurgical compositions are described in which organic amine-based lixiviants and organic amine-based pre-lixiviants are utilized in the selective recovery of rare earth elements. The lixiviant species can be regenerated in situ, permitting the organic amine to be used in substoichiometric amounts.

Lixiviant for rare earth production

Methods and compositions are described in which amine-based compounds are utilized in the recovery of rare earth elements from solution. The rare earth elements are recovered selectively and sequentially.

Methods and composition for sequential isolation of rare earth elements

Hydrometallurgical systems, methods, and compositions are described in which organic amine-based lixiviants are utilized in the selective removal of carbonate-forming alkaline earth elements from slag. The resulting processed slag has a reduced tendency to form carbonate salts on environmental exposure, and reduced tendency to fracture due to the formation of such salts. The lixiviant used can be regenerated and recycled for use in subsequent iterations of the process.

Processed slag and methods for producing same

Hydrometallurgical systems, methods, and compositions are described in which organic amine-based lixiviants are utilized in the selective recovery of alkaline earth elements. The lixiviant can be regenerated and recycled for use in subsequent iterations of the process. Multiple alkaline earth elements can be recovered from a sample in parallel or in serial applications of the disclosed methods.

Refining agents for alkaline earth production

Hydrometallurgical systems, methods, and compositions are described in which organic amine-based lixiviants are utilized in the selective recovery of rare earth elements. The lixiviant can be regenerated in situ, permitting the organic amine to be used in substoichiometric amounts.
