You are apparently interested in historical literature dealing with
direct-charged lead ores rather than blast (or shaft) furnace smelting of sintered
galena concentrates.
Leaving aside reverberatory and hearth smelting, a short reference to shaft
furnaces is on p. 105, The Metallurgy of Lead, by Henry F. Collins, London,
1910, Charles Griffin & Co.
wherein it is stated, "The only furnace of this kind which has been
successfully used on pyritous lead ores is the well-known Gerstenhofer [reference
is given], which at Freiberg puts through in twenty-four hours about 60 tons
of a pyritous ore containing 18 percent. galena, 60 per cent. pyrites, and
22 per cent. gangue, and roasts it down to about 7 per cent. sulphur.
Ordinary lead ores, properly so called, could not, of course, be roasted in such a
furnace at all."
Another old reference I checked, The Metallurgy of Lead, by H. O. Hofman,
2nd ed., 1893, New York, Scientific Publishing Co., states on p. 132, "... in
the Hartz Mountains, in Prussia, concentrated galena ores have been for
years, and still are, smelted raw in the blast-furnace. In other districts of
Germany as well as in France the sulphide ores are always roasted before they
come to the blast-furnace, and oxidized ores are of such rare occurrence
that they are hardly treated separately."
