The calcium carbonate is separated by filtration, and the solvent is returned to the extractor, as the ammonium salt is regenerated in the carbonator (Figure 1).Both the calcium carbonate and the unreacted part of the slag from the extractor (slag residue) are washed in order to remove solvent remnants (mainly ammonium salt).

The iron oxides are reduced in the upper region of the furnace. In the middle region, limestone (calcium carbonate) decomposes, and the resulting calcium oxide combines with silica and silicates in the ore to form slag. The slag is mostly calcium silicate and contains most of the commercially unimportant components of the ore:
