A method, apparatus and system for processing a composite waste source, such as e-waste, is disclosed. The composite waste source may comprise low-, moderate and high-melting point constituents, such as plastics, metals and ceramics. The composite waste source is heated to a first temperature zone, causing at least some of the low-melting point constituents to at least partially thermally transform. The composite waste source is subsequently heated to a second, higher, temperature zone, causing at least some of the moderate-melting point constituents to at least partially thermally transform. At least some of the at least partially thermally transformed constituents may be recovered. The method, apparatus and system disclosed may provide for the recovery and reuse of materials which would otherwise be sent to landfill or incinerated.

A process for a producing crude solder product and a copper product includes the steps of providing a black copper comprising >=50% wt of copper together with >=1.0% wt of tin and/or >=1.0% wt of lead, and refining a first portion of the black copper to obtain a refined copper product together with at least one copper refining slag. The process further includes the steps of recovering a first crude solder product from the copper refining slag, thereby forming a solder refining slag in equilibrium with the first crude solder product, and contacting a different portion of the black copper with the solder refining slag thereby forming a spent slag and a lead-tin based metal, followed by separating the spent slag from the lead-tin based metal.

The present invention relates to a method for recovering a positive electrode active material from a lithium secondary battery including: 1) separating a positive electrode into a collector and a positive electrode part; 2) removing an organic substance by firing the separated positive electrode part; 3) washing the fired resultant and removing remaining fluorine (F); 4) adding a lithium-containing material into the washed resultant and firing to recover a lithium transition metal oxide.

Disclosed is a battery pre-processing apparatus and method. The battery pre-processing apparatus includes a control mechanism, as well as an automatic feeding mechanism, a transmission mechanism, an electricity monitoring actuator, a non-destructive testing mechanism, a flexible grabber mechanism, a multi-station operating table, an automatic cutting mechanism, an automatic separation mechanism, and a recovery and dust collection system that are each electrically connected to the control mechanism.

Provided are: an alloy powder that can be obtained from a waste lithium ion battery, wherein the alloy powder can be dissolved in an acid solution and enables recovery of metals contained in the alloy powder; and a method for producing the alloy powder. This alloy powder contains Cu and at least one of Ni and Co as constituent components, wherein a portion having a higher concentration of the at least one of Ni and Co than the average concentration in the entire alloy powder is distributed on at least the surface, and the phosphorus grade is less than 0.1% by mass. The method for producing the alloy powder includes a powdering step for powdering a molten alloy using a gas atomization method, the molten alloy containing Cu and at least one of Ni and Co as constituent components and having a phosphorus grade of less than 0.1% by mass.

A method for recovering a valuable substance from a lithium ion secondary battery is provided. The method includes a thermal treatment step of thermally treating a lithium ion secondary battery containing aluminum, carbon, and a copper foil as constituting materials, and a wet sorting step of applying an external force to a thermally treated product obtained in the thermal treatment step in the presence of a liquid, to sort the thermally treated product into a heavy product and a light product containing copper.

A process for treating spent lithium ion batteries to recover metals is disclosed. The process includes discharging the spent lithium ion batteries. The discharged lithium ion batteries are shredded and roasted in a furnace to produce roasted material. The roasted material is sieved to separate a coarser fraction and a finer fraction. The coarser fraction comprises aluminium chips and copper chips. The finer fraction is further treated to recover copper, cobalt, and nickel sequentially with a purity of 99.3-99.9%. The process also recovers manganese as manganese dioxide and lithium as lithium carbonate. The process does not generate any solid waste as all the metals and by-products such as carbon powder and gypsum cake are saleable.

The present disclosure relates to the production of lithium-enriched compositions from lithium-ion batteries, and the processing of those compositions for the economic recovery of lithium compounds useful for commercial and industrial applications.
