LIGNOFLOT

Pre-study: Use of organosolv lignin hydrophobic nanoparticles as biodegradable flotation collectors.

Project team: Paul Christakopoulos (project leader), Katerina Hruzova, Leonidas Matsakas, Ulrika Rova

Partners: Boliden Mineral; Sveaskog

Duration: 2018

Funded by Vinnova’s Strategic Innovation Programme for Swedish mining and metal producing industry

The objective of the LIGNOFLOT pre-study is to demonstrate the potential of using lignin particles as a flotation collector, able to enable selective recovery of copper and other minerals in the presence of iron sulphides without the presence of a depressant.
