Nov 04, 2018· Hot Metal. Hot metal (HM) is the output of a blast furnace (BF). It is liquid iron which is produced by the reduction of descending ore burden (iron ore lump, sinter, and pellet) by the ascending reducing gases. HM gets collected in the hearth of the BF. From the hearth, the HM is tapped from the taphole of the BF after an interval of time.
The ore is Zn-rich at the top and Cu-rich at the base. Geometry Typically tabular to lensoid, and range from less than 1 to more than 150 million tonnes. They often occur in clusters. Economic minerals Chalcopyrite (Cu), sphalerite (Zn), galena (Pb), silver and gold. The dominant gangue minerals are quartz, pyrite and pyrrhotite.
The antimony (Sb) content of the Rockliden complex Zn–Cu massive sulphide ore lowers the quality of the Cu–Pb concentrate. The purpose of this study is to characterise the Sb mineralogy of the deposit. The Sb-bearing minerals include tetrahedrite (Cu,Fe,Ag,Zn)12Sb4S13, bournonite PbCuSbS3, gudmundite FeSbS and other sulphosalts.
