Concentration - LKAB

Flotation. Through a chemical treatment known as flotation, the ore is further purified, for example of the phosphorus mineral apatite. In the flotation process, a reagent is added to the slurry. The reagent binds the apatite in small air bubbles, which are removed from the slurry as foam. Additives and filtration

Level Control of Flotation Tanks at LKAB : Control Design ...

Flotation is one part of LKAB's refining process where minerals are separated from iron ore in cascade connected tanks. A good level control in the flotation tanks is vital to get a high recovery of the iron. Nominal and robust performance of different level controllers are compared in the study.

Anrikning - LKAB

Slurryn filtreras därefter till en bestämd fukthalt. När anrikningen av malmen är klar är det dags för pelletisering. Anrika betyder rening av finmald malm genom separering till ett koncentrat av järnmalmspulver med mycket hög renhet. Flotation är en kemisk process för partikelseparering.

Apatite production in Malmfälten | LKAB Minerals |

LKAB is now involved in an environmental permitting process. This process includes new comprehensive permits for the operations in Kiruna and Malmberget. We estimate this process may take more than five years. Changes in LKAB’s operations, such as the addition of an apatite plant, could impact the entire permitting process.
