Lab-scale equipment for solvo/hydrometallurgy

1. Pretreatment of solid materials

2. Lab-scale leaching studies

Solid materials, sludges and suspensions are fully characterised and pretreated to allow further processing. During a lab-scale leaching study, the optimal leaching process is developed for the desired application. All leaching parameters are optimised, including liquid-to-solid ratio, lixiviant concentration, time, temperature and shaking speed.

3. Liquid-liquid solvent extraction studies

4. Lab-scale ion-exchange chromatography studies

Lab-scale solvent extraction studies focus on the development of a solvent extraction process to selectively separate targeted metals ions from a feed solution, for instance produced during a previous leaching study. SOLVOMET also has key expertise in non-aqueous SX systems. Lab-scale ion-exchange chromatography studies allow the design of a metal-separation process using ion-exchange resins and various other adsorbents, which are mostly suitable for the selective valorisation of various diluted streams and solutions.
