So much work has been done in thisline to separate copper from the ores thatIt is surprising that any possible methodhad been overlooked, yet a singular acci-dent revealed something in the BaltimoreCopper Works which is likely to bring intouse a new refining process. At the establishment referred to the re-verberating furnaces are connected with agreat chimney by means of long under-ground passages, called culverts, inwhich more or less oxydi2ed copper, aswell as sulphides, arsenides and othercompounds, is carried off in the form of the culverts, and a lected to be worked
