Process parameters and microprocesses

Many factors simultaneously influence the outcome of beneficiation, extraction, and refining processes. Creating a fundamental understanding of the underlying mechanisms and microprocesses controlling the process performance is key to efficiency and sustainability. Our research spans the following research topics:

Particles

We analyze particles to predict their behavior in se­paration processes and to understand the factors driving or hindering se­paration processes.

Colloid and interface science

To control the interactions between the different phases and reagents in interfacial se­paration processes, we quantify the physical and physico-chemical properties of particle surfaces.

Process kinetics and thermodynamics

By measuring reaction rates and studying processes such as complexation, we improve the performance efficiency of different process ­techno­logies and the quality of the reco­vered minerals and metals.

Metal-slag-gas equilibria

We improve the efficiency of metallurgical recycling processes while increasing product quality by researching the so-called metal-slag-gas equilibria to make otherwise hard to process metals such as zinc or contaminants such as arsenic and lead accessible.
