Sulphidizing Of Cerussite, Emil A. Kovacevich
Sulphidizing Of Cerussite, Emil A. Kovacevich
Bachelors Theses and Reports, 1928 - 1970
The oxide minerals, such as cerussite, are not as amenable to flotation as the sulphide minerals. Sulphidization is the usual means used today to increase the recovery of an oxide flotation; however, sulphidization under the most advantageous conditions does not yield very satisfactory recoveries.
The Electrolytic Purification Of An Impure Cadmium Sulfate Solution With A Cell Utilizing A Mercury Cathode And A Lead Anode, W. D. Mcmaster
The Electrolytic Purification Of An Impure Cadmium Sulfate Solution With A Cell Utilizing A Mercury Cathode And A Lead Anode, W. D. Mcmaster
Bachelors Theses and Reports, 1928 - 1970
Cadmium is produced solely as a by-product and all cadmium of commerce is obtained from zinc ores. It is a rare occurrence when zinc deposits are found which do not contain some cadmium.
Electrowinning Versus Electrorefining Of Blister Copper, Frank J. Vorell
Electrowinning Versus Electrorefining Of Blister Copper, Frank J. Vorell
Bachelors Theses and Reports, 1928 - 1970
In the following sections of this report, I will discuss as fully as possible both the theoretical and practical aspects of the roasting, leaching, and electrowinning steps, as well as the economic considerations of the process. The results of my laboratory work will, of course, be integrated to the process.
The Influence Of Copper Upon The Age Hardening Properties Of Steel, Andre Rey
The Influence Of Copper Upon The Age Hardening Properties Of Steel, Andre Rey
Bachelors Theses and Reports, 1928 - 1970
The virtues of alloy steels have been widely publicized in both technical literature and everyday advertising. Nearly everyone possessing a slight knowledge of metallurgy knows the beneficial effects of chromium in the manufacture of stainless steels, or the importance of nickel, molybdenum, vanadium, and other common elements used to alloy steels.
Ferromagnetic Alloys In The System Cu-Mn-Zn, W. Michael Yim
Ferromagnetic Alloys In The System Cu-Mn-Zn, W. Michael Yim
Bachelors Theses and Reports, 1928 - 1970
The purpose of this investigation is to determine whether ferromagnetic alloys exist in the ternary system Cu-Mn-Zn analogous to the other Heusler alloys. The work in this thesis is a preliminary investigation on these alloys using a common metallographic research technique and augmented with X-ray methods.
