Solutions for Lithium Refining & Extraction

Lithium Refining Additive

By 2030, lithium demand could outstrip supply by 300,000 tons. Molhill has developed a solution to rapidly enable the industry to meet this demand.

Our solution for lithium carbonate refining is a drop-in, low-dosage composition of environmentally-benign biochemicals to increase refinery throughput.

Carbonate Crystallization

Additive formulation increases throughput of the 2-stage crystallization process

  • Up to 40% decrease in reactor/crystallizer retention times

  • Increased tolerance of troublesome impurities including sulfate, boron

  • Low dosage & recyclable

  • Drop-in, no entrainment in final product

    • Repeated testing has validated no impact to final lithium carbonate product for CAM synthesis

    • Consistent 99.9% purity meeting superior battery-grade specs

DLE Enhancement

For brines and flowsheets capable of using a single stage crystallization, Molhill’s additive can be introduced during DLE wash & desorption to increase yield and stabilize impurity management with changes in brine composition. Reach out to see if our additive could be an enabling solution for your project.

Solutions for Hard Rock Extraction & Refining

Molhill’s has been developing a repurposed formulation of its product for refinement in hard rock & clay conversion to lithium carbonate.

Projected Customer Impact

  • Savings on Operational costs / reagent usage

  • CAPEX savings on downstream refining processes

If you are a project developer looking for optimized solutions for your conversion plant, Molhill’s additive offers a unique metallurgical solution using known and scaled process equipment.

Process Features

  • Low additive dosage: 1 kg additive for every ton of lithium carbonate refined

  • Alkaline and acidic leach compatible

  • Optionality to reduce costs via calcination optimization
