Pagina 67 - Imrned lime mixed with coal tar was tried. The result was a foregone conclusion, but nevertheless we were hunting for straws to grasp and it was given a fair and impartial trial. Just enough tar was used to stick the lime together, and when in place the lining was baked with a coke fire to drive off the gaseous portion of the tar. A charge was run into the vessel and blown until the flame at the nose indicated the complete oxidation of the iron. The converter was then turned down to skim, but in...

Pagina 47 - Accordingly it was decided that another man should try to run them, and Dr. Charles Harbordt was sent there to do the metallurgical work. The doctor is a valued friend of the writer, and was offered every assistance that the light of past experience could give as to the running of these furnaces.

Pagina 79 - Hixon at the old Marcus Daly smelter, Anaconda, and in his book (p. 81) he says : " The silicious lining is as much a part of the process of copper converting as magnesia lining is in the basic Bessemer treatment of phosphoric iron, and it is suicidal to attempt any other kind of lining, either water-jacketed or basic. The improvement, if there is to be any, is to be in the line of mechanical devices, and the use of silicious ores to replace the expensive quartz and clay linings.
