Alternatively, the dressed ore can be used to produce iron-rich sinters i.e. semi-fused and solidified lumps of iron oxide. Previously, the ore-based steelworks in Sweden had their own sinter plants but nowadays pellets are mainly used as a feedstock in the production of ore-based steel. The last Swedish sinter plant was shut down in 1995.
