PRECIOUS METALS & RARE EARTHS TREATMENT
Hydrometallurgical technologies for high-purity critical material recovery
Turning Complex Feedstocks into Valuable Resources
- Integrated approach, from feedstock characterization to flowsheet definition and industrial scale-up
- Flexibility in producing high-purity metals, salts or intermediates for downstream uses
- Optimization of reagent and water consumption
- Support throughout the entire development cycle
Precious metals and rare earths treatment technologies enable the recovery of high-value elements from ores, concentrates, end-of-life batteries, spent catalysts, electronic waste, ashes, slags and other industrial residues.
The complexity and variable compositions of these resources, combined with low concentrations of the target metals and the presence of interfering species, require advanced and highly selective treatment solutions.
By integrating pretreatment, selective leaching, solution purification and final product recovery, our process is designed to maximize yield, selectivity and purity while optimizing reagent, water and energy consumption.
Industrial Applications of Precious Metals and Rare Earths Treatment
Main industrial applications include:
- Recovery of lithium, nickel, cobalt and manganese from battery black mass
- Recovery of rare earth elements from permanent magnets, Waste Electrical and Electronic Equipment (WEEE), mining residues and industrial by-products
- Separation and refining of gold, silver and platinum group metals
- Leaching and valorization of ashes, slags, abatement dusts and filtration residues
- Circular schemes to recycle recovered metals, reagents and process water
