The world class Expert in the circular economy of urban mines
Delivering value through recovered materials and process innovation.
The RandRock recycling process recovers the main active materials of lithium-ion-batteries in a small-footprint, environmentally friendly and sustainable manner such that these materials can be reused in manufacturing battery cathode. A lithium-ion-battery is a rechargeable battery made up of an anode, cathode, separator, electrolyte, and two current collectors, all of which are enclosed within an outer casing.
Here How it works:
Our proprietary Spoke & Hub Technologies use a combination of mechanical safe size reduction and hydrometallurgical resource recovery specifically designed for lithium-ion battery recycling.
Spoke Products:
At RandRock’s Commercial Spokes, lithium-ion batteries of all formats, chemistries and states of charge are processed through a mechanical process. This process breaks down the batteries to inert materials without the risk of fire or explosion, and subsequently separates the resulting materials into two main product lines: battery materials (black mass) and mixed copper/aluminium.
Battery Materials
The Spoke produces a product that consists of a mix of cathode and anode battery materials, including lithium, nickel and cobalt, as well as graphite, copper and aluminum.
Mixed Metals
The Spoke produces copper and aluminum metals from the processing of lithium-ion batteries. These are primarily made up of the foils found within the lithium-ion batteries.
Hub Products:
At RandRock’s Hub, battery materials (black mass) are run through the hydrometallurgical circuit to produce individual metal sulphate and carbonate products with the purity levels required to be used in cathode and precursor production. By re-inserting the Hub products back into the lithium-ion battery supply chain.
Lithium Carbonate
High purity, micronized lithium carbonate derived from end-of-life lithium-ion batteries. Suitable for use in many applications including lithium-ion and lithium polymer batteries, as well as glass and ceramics manufacturing.
Cobalt Sulphate
High purity cobalt sulphate derived from end-of-life lithium-ion batteries. Suitable for the production of cobalt containing cathode materials for lithium-ion and lithium polymer batteries.
Nickle Sulphate
High purity nickel sulphate derived from end-of-life lithium-ion batteries. Suitable for the production of nickel containing cathode materials for lithium-ion and lithium polymer batteries.
Manganese Carbonate
High purity manganese carbonate derived from end-of-life lithium-ion batteries. Suitable for use in many chemical applications.
