Flotation Of A Complex Sulphide Ore Containing Tetrahedrite, James C. O'Dea, Lorimer W. Hoar
Flotation Of A Complex Sulphide Ore Containing Tetrahedrite, James C. O'Dea, Lorimer W. Hoar
Bachelors Theses and Reports, 1928 - 1970
The ore investigated in this thesis is a zinc-copper-lead ore. Microscopic analysis of this complex sulphide ore showed it to contain pyrite, sphalerite, arsenopyrite, galena, chalcopyrite, tetrahedrite, and covellite, with quartz as the gangue constituent.
Bright Electroplating Of Copper In The Acid Bath, Elwood K. Jensen
Bright Electroplating Of Copper In The Acid Bath, Elwood K. Jensen
Bachelors Theses and Reports, 1928 - 1970
Plating of various objects with mirror-like surfaces of chromium, nickel, and other metals has expanded considerably during the past decade, and now ranks as an important enterprise, particularly with respect to the automotive industry.
Electrolytic Deposition Of Iron, Irving M. Kenoffel
Electrolytic Deposition Of Iron, Irving M. Kenoffel
Bachelors Theses and Reports, 1928 - 1970
In this thesis the purpose was to obtain a good iron deposit from a relatively simple bath. The deposit was to be of good nature and low in Carbon content. Also included is a summary of the uses to which electrolytic iron can be put as well as a summary of work done by other researchers in depositing iron electrolytically.
Concentration By Flotation Of A Complex Galena - Sphalerite - Chalcopyrite Ore From The Nine Mile District Near Missoula, Montana, Truxton J. Fisher, John L. Tokich
Concentration By Flotation Of A Complex Galena - Sphalerite - Chalcopyrite Ore From The Nine Mile District Near Missoula, Montana, Truxton J. Fisher, John L. Tokich
Bachelors Theses and Reports, 1928 - 1970
At the present time ore bodies being mined are becoming more and more complex in mineral association, thus presenting a more difficult problem in their concentration. Lead-zinc sulphide ores are among the more common ores which present such difficulties.
The Electrodeposition Of Iron-Manganese Alloys, Earl C. Roberts
The Electrodeposition Of Iron-Manganese Alloys, Earl C. Roberts
Bachelors Theses and Reports, 1928 - 1970
Various electrolytes were experimented with in an attempt to deposit an iron-manganese alloy. An Alloy was obtained from a solution containing ferrous ammonium sulfate, manganous sulfate, and ammonium sulfate. Further experimentation was done in an effort to determine the optimum conditions of deposition and the highest manganese alloy which could be produced.
