An apparatus for carrying out size reduction of battery materials under immersion conditions having a battery inlet and at least a first comminuting device disposed within a housing and configured to cause a size reduction of the battery materials to form reduced-size battery materials and to liberate electrolyte materials and a black mass material comprising anode and cathode powders from within the battery materials. An immersion liquid can be within the housing and can submerge the first comminuting device so the black mass material and the reduced-size battery material are entrained within the immersion liquid to form a sized-reduced feed stream. A feed outlet may be downstream from the first comminuting device.

In some examples, the product comprises a container, shot blasted pieces of aluminum alloy wheels and an alloying supplement. In some examples, the product also comprises an indication on the container of a composition estimate of the combined shot blasted pieces and alloying supplement. In other examples, the indication and/or the alloying supplement may be provided by a company in the business of providing alloying supplements.

A method for processing accumulators, batteries and the like, which contain lithium, lithium ions, sodium, potassium and/or nickel as active components. According to the invention, the following steps are carried out; introducing an accumulator, a battery, cell or the like, that contains lithium, lithium ions, sodium, potassium and/or nickel, into a chamber/reactor (13,23); introducing water (H2O) (B, B2) in to the reactor (13,23); bringing the content of the reactor (13) to a temperature between 120 C. and 370 C. at a pressure between 2 and 250 bar.

The invention relates to a method for recycling used lithium batteries containing the steps: (a) digestion of comminuted material (10), which contains comminuted components of electrodes of lithium batteries, using concentrated sulphuric acid (12) at a digestion temperature (T.sub.A) of at least 100 C., in particular at least 140 C., so that waste gas (14) and a digestion material (16) are produced, (b) discharge of the waste gas (14) and (c) wet chemical extraction of at least one metallic component of the digestion material (16).

Described herein is a method for recycling aluminum alloy wheels. The method includes the steps of providing a feed of aluminum alloy wheels of a particular alloy; fragmenting the aluminum alloy wheels into a plurality of fragments, such that newly exposed surfaces of the plurality of fragments have an interior composition; determining a newly exposed surface indicia for distinguishing each newly exposed surface in the feed of aluminum alloy wheels; determining an aggregate composition estimate by determining a plurality of composition measurements of the material of fragments of the plurality of fragments; and providing the plurality of fragments, and the aggregate composition estimate, for use in manufacturing at least one component made from aluminum alloy.

Certain method embodiments are described and useful for recycling permanent magnet materials (e.g. permanent magnet alloys) and battery materials (e.g. battery electrode materials) to extract critical and/or valuable elements including REEs, Co and Ni. Method embodiments involve reacting such material with at least one of an ammonium salt and an iron (III) salt to achieve at least one of a liquid phase chemical reaction and a mechanochemical reaction.

A management system for a hard drive dismantling system automatically monitors the operation and the output of the dismantling system either remotely or onsite. In one embodiment, the number of hard drives processed by the system is determined and a contract value is determined in real-time. A distributed ledger is employed. Payments are automatically transferred between a customer and a service provider according to a contractual arrangement. The market values of various components, such as rare earth materials, are also optionally provided.

An apparatus and an arrangement for the (pyro)metallurgical treatment of electrical and/or electronic scrap or components, which are in particular configured in such a way that substantially uncontaminated electrical and/or electronic scrap or components thereof can be processed without impurities. The apparatus or the arrangement includes a melting reactor, which has a cooler. The present invention also relates to the use of the apparatus or the arrangement for the metallurgical treatment of electrical and/or electronic scrap or components and to the obtainment of raw copper or a precursor thereof, as well as to methods for the (pyro)metallurgical treatment of electrical and/or electronic scrap or components.

The present invention concerns a process for the recovery of lead from a lead pastel electrolytically, where the pastel contains lead sulfate. The process provides for the leaching of the non-desulfurised pastel and the subsequent removal of the sulfates by precipitation; the leachate containing the lead ions is then subjected to electrolysis for the recovery of metal lead. The present invention further relates to a process for the recovery of lead accumulator components, wherein the lead contained in the pastel of the accumulators is recovered according to the aforesaid process.
