The molten matte (CU 2 S + FeS) is transferred to a Bessemer converter, a pear shaped vessel lined with MgO or SiO 2 and heated by hot air blown through tuyers and mounted in such a way that it can be filled in any direction. It is mixed with some silica as flux and heated by passing hot air through tuyers. The air oxidises FeS to FeO, which combine with silica forming a slag.
