Circular and fossil-free
Directly adjacent to LKAB’s production facilities an apatite plant will be built. Using a flotation process, this plant will produce a pure apatite concentrate from the tailings sand.
LKAB’s Circular Industrial Park
The apatite concentrate will be transported via rail to the industrial park located on the coast in Luleå, Sweden, where it will be further processed.
At the apatite is dissolved with hydrochloric acid to create a pure phosphorus product and separate REEs and fluorine products. Phosphorus is then processed with ammonia to mineral (phosphate) fertiliser. Hydrochloric acid is regenerated with the aid of sulphuric acid and produces gypsum.
Reduction of CO2 emissions
The planned ReeMAP process use existing material streams and will therefore not entail the opening of a new mine. This will minimise land usage and save energy. Here, considerable reductions in emissions can be realised, though these have not been calculated.
Energy from renewable sources will be used in the processes. Luckily, Northern Sweden is well-positioned, with access to large-scale production of hydro and wind power.
Own production of input materials is the last puzzle piece. This is where much of the savings in terms of carbon-dioxide emissions can be realised.
