Description. The occurrence and deportment of manganese in a number of ferromanganese and Mn-bearing iron ore samples from supergene-upgraded deposits, as well as from magnetite banded iron formation (BIF) and magnetite skarn deposits, was characterised in order to provide a basis for improved understanding of the processing characteristics of different ore types and investigate the potential ...
Precious metals. Precious metals are rare, naturally occurring metallic chemical elements of high economic value. Chemically, they tend to be less reactive than most elements. They are usually ductile and have a high lustre. In history precious metals were important as currency but are now regarded mainly as investment and industrial commodities.
