1. Introduction to the extraction of metals. What methods can be used in extracting metals from mineral ores? The Earth's crust contains many different rocks.. Rocks are a mixture of minerals and from some we can make useful substances.. A mineral can be a solid metallic or non–metallic element or a compound found naturally in the Earth's crust.
Flow Sheet for Pyrometallurgical Extraction of Zn In the condenser. a sheet-iron extension to the condenser as dust. In the retort zinc is reduced according to the reaction: ZnO + CO =Znvapour + CO2 The nose of the retort opens into a condenser of fire clay. Pb and Cu may also be reduced in the retort. Material left in the retort is called …
