Annual number of pyrites processors, gross volume of pyritic sands treated in Victoria and minimum mercury loss per year (data source: MSV, 1870–1891). Pyrites were treated both by individual mines and by specialised processors, with the latter tabulated between 1876 and 1888. DOI: https://doi.org/10.1525/elementa.432.t1
