Six Service Lines. One Scoped Engagement.
From lithium extraction and rare earth processing to modular plant engineering and process consulting — each engagement is scoped to your site, your residue stream, and your production targets.
Lithium Extraction
Rare Earth & Mineral Extraction
Consulting Services
On-site lithium recovery engineered to your brine, spodumene, or clay deposit. Process design, reagent selection, and output specification matched to battery-grade requirements.
Separation and concentration of rare earth elements from primary ores, industrial by-products, and mining residues. Scalable systems built for real feed variability.
Technical due diligence, process audits, and supply chain strategy for operators evaluating critical mineral assets or planning extraction capacity.
Technological Expertise
Advanced Materials Processing
Modular Extraction Plants
Process engineering knowledge applied across extraction chemistry, residue treatment, and refining unit operations — deployed as embedded support or standalone technical review.
Skid-mounted, scalable extraction systems engineered for your site. Covers plant construction, residue reprocessing, and waste management. Details at the dedicated page.
Refining and conversion of critical mineral concentrates into specification-grade advanced materials for battery and industrial supply chains.
Every proposal is built around your feed material, residue chemistry, and output specification. AB Croll scopes process engineering, equipment selection, and deployment logistics to the constraints of your operation — not a catalogue configuration.
