The unsung heroes of copper electro-refinery

Figure 1: Copper electrorefining tankhouse (https://copperalliance.org.uk/)

Copper is a soft, malleable, and ductile metal with very high thermal and electrical conductivity and because of these properties, it is the undisputed material of choice for conducting electricity. The quality of the copper should be very good for electrical applications. Bad quality dramatically changes the electrical conductivity and workability. The following qualities are important for copper; Chemical property: ...

Making amorphous slag

a beautiful shiny amorphous slag obtained after quenching

Work Packages 1 and 2 of the SOCRATES project are working on the extraction and recovery of critical and economically important metals that are present in the investigated tailings, sludges, slags and ashes. This leaves behind residual mineral matrices that can be used in our Work Package 3: “Residual matrix valorization”, possibly requiring prior treatment processes. By activating these (treated) residues ...

The colourful coordination chemistry

Figure 1- Different solutions of CuO and Cu2O­ in DESs

During your childhood, have you ever mixed dish soap with oil, vinegar with coffee, shampoo with coke? If not, you have no idea what you are missing! As a kid I was always mixing different liquid products (e.g. detergents in my home, dressings at restaurants) pretending to be a chemist. Mixing things and waiting for the result was always my ...

What do you know about plasma?

Figure 5: Plasma gasification (left), plasma fuming (right)

Plasma is the fourth fundamental state of matter in our universe (we don’t know about the states of matter in other universes yet 😉). In simple words, plasma happens when a gas is brought to an ionized state. But is it all there is to it? Let’s see what else can we know! Let’s imagine, on a stormy night, you ...

Deep eutectic solvents – A warm relationship

Ionic Liquids and their properties [2]

If you have read my previous articles, you might have noticed that my PhD is about deep eutectic solvents and their application in electrochemical extraction of critical metals from industrial wastes (quite a mouthful, but allow me to explain 🙂 ). Metallurgists and Chemists might be wondering “Why deep eutectic solvents for extraction of metals? Why? I could just use ...
