chalcocite
This term is a technical mineralogical designation used primarily in geology and mining. It carries a neutral, scientific connotation and is rarely encountered outside of professional geochemical or industrial contexts related to copper extraction.
As a chemical species and mineral name, it is treated as an uncountable mass noun. It refers to the substance itself rather than individual units, meaning it does not typically take a plural form in scientific literature.
