There's John Percy's four-volume "A Treatise on Metallurgy", published between 1860 and 1880 - probably a scan of it online somewhere given its age, though I believe the Historical Metallurgy Society did a reprint edition at one point?
There is a reprint of Percy's "The Metallurgy of Lead, Including Desilverization and Cupellation" published 1870, but not by HMS. Don't know if it's still available as it's some years since I bought it.
