Abstract: The present disclosure broadly relates to a process for recovering cobalt from lithium-ion batteries using thermal techniques.

Abstract: 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.

Abstract: The present invention relates generally to methods for the preparation of nickel-based alloys using waste materials, and more particularly to the preparation of nickel-based alloys using spent batteries.

Abstract: The present invention relates generally to composite products, in particular glass-based composite products, and the manufacture thereof.

Abstract: A method of hardening a surface of a ferro-alloy object, the method comprising at least partially gasifying a carbon-containing polymer to form a hardening material source; and exposing the object to the hardening material source, such that the hardening material source and the surface of the object react, thereby hardening the surface of the object.

Abstract: A method for producing a ferro-alloy in an electric arc furnace is disclosed. The method comprises the steps of removing steel from a carbon-containing organic material, and charging the furnace with the carbon-containing organic material product.

Abstract: A method for producing a ferro-alloy in an electric arc furnace is disclosed. The method comprises the step of charging the furnace with an un-agglomerated carbon-containing polymer such that the polymer functions as a slag foaming agent.

Abstract: A method for recarburising a molten ferro-alloy in a ladle or ladle furnace comprises the step of adding a carbon-containing polymer to the ladle or furnace. The polymer is adapted to function as a recarburiser of the ferro-alloy. In this regard, the polymer can have a format which, when it contacts the molten ferro-alloy, promotes dissolution of carbon from the polymer into the molten ferro-alloy.
