A decoating system includes a dust cyclone and cooled conveyor. The dust cyclone is configured to receive an exhaust gas from a decoating kiln, filter organic particulate matter from the exhaust gas as dust, and discharge the dust at a discharge temperature. The cooled conveyor is configured to receive the dust from the dust cyclone and cool the dust to a dust processing temperature that is less than the spontaneous reaction temperature.

A process for processing a leach solution of black mass of spent alkaline batteries which leach solution comprises metals dissolved to an acidic solution. The process comprises removing of one or more elements from the leach solution by a cementation operation by applying at least one non-noble metal in a metal form as a cementation agent and one or more additional cementation agents from both sulphate and nitrate groups to process the leach solution into a product of at least manganese- and zinc-containing sulphate solution which is suitable for use as micronutrients alone, in fertilizers and/or together with a plant protective agent to aid growth and health of plants. In addition, the invention also relates to a process for processing a black mass of spent alkaline batteries.

A method for processing lithium ion battery scrap includes a leaching step of leaching lithium ion battery scrap and subjecting the resulting leached solution to solid-liquid separation to obtain a first separated solution; an iron removal step of adding an oxidizing agent to the first separated solution and adjusting a pH of the first separated solution in a range of from 3.0 to 4.0, then performing solid-liquid separation and removing iron in the first separated solution to obtain a second separated solution; and an aluminum removal step of neutralizing the second separated solution to a pH range of from 4.0 to 6.0, then performing solid-liquid separation and removing aluminum in the second separated solution to obtain a third separated solution.

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.

The present disclosure relates to a process for recovering vanadium in the form of iron vanadate from a gasifier slag. The process comprises pulverizing the slag to obtain pulverized slag (2). The pulverized slag (2) is soaked in water (6) and an alkali salt (4) to obtain a slurry (8), followed by roasting the slurry in the presence of air to obtain roasted slag (12) which is leached (14) to obtain a first solution (18). The first solution (18) is heated at a temperature in the range of 60 C. to 80 C. while adding an iron salt (17) in an amount in the range of 10 wt % to 60 wt % at a pH in the range of 4 to 10, to obtain a second solid residue (21) which is dried to obtain iron vanadate (24).

A method of making a zeolite comprises: adding a zeolite seed to a leach solution containing silicon and aluminum; and heating the leach solution to obtain the zeolite. The leach solution can be made by mixing coal ash with a basic stream, thereby creating (i) a leach solution containing silicon and aluminum, and (ii) leached ash; and separating the leach solution from the leached ash.
