Processing Lab

Focused on comminution and separation of primary as well as secondary materials, this section is equipped with jaw and roll crushers, instrumented Bond ball and rod mills, vibratory mill, horizontal and vertical stirred media mills, as well as systems for magnetic (low and high intensity), electrical, and gravimetric separation (spiral, shaking tables, jig, Knelson concentrators). Flotation is carried out using Wemco, Agitair, and GTK automatic scraper cells, while classification is performed using hydrocyclones of various sizes and air classifier.

Flotation

Flotation is one of the key concentration methods in mineral processing, and its development always begins at the laboratory scale. Metallurgical test work is an essential step, carried out using laboratory flotation cells with only a few liters of sample. In the lab flotation cell, ore samples are floated for a defined period, and the froth can be scraped either manually or automatically. The equipment enables research across a wide range of ore types, including both oxides and sulfides.
