The Presence Of Rhenium In Montana Manganese Ores., Henry E. Swanson
The Presence Of Rhenium In Montana Manganese Ores., Henry E. Swanson
Bachelors Theses and Reports, 1928 - 1970
Rhenium properties offer many interesting possibilities, therefore any ores containing rhenium would be of considerable value. Its close relationship to manganese in the periodic table led to the belief that manganese ores would be an excellent place to search for the metal. Investigation of the literature of rhenium revealed that no ore was known to contain more than 0.001 per cent of rhenium.
The Electroplating Of Cadmium From Sulfate Solutions, Lewis S. Prater
The Electroplating Of Cadmium From Sulfate Solutions, Lewis S. Prater
Bachelors Theses and Reports, 1928 - 1970
It has been proven that cadmium forms a very satisfactory plate on steel, which has to withstand severe corrosion, especially the corrosion of sea water and spray. The metal is now successfully plated electrolytically from cyanide solutions, but wherever work is carried on with cyanide, there is great danger of poisoning to the workers.
The Electrowinning Of Copper From Roasted Sulphides, Thomas B. Linn
The Electrowinning Of Copper From Roasted Sulphides, Thomas B. Linn
Bachelors Theses and Reports, 1928 - 1970
A hydrometallurgical process for the recovery of copper from flotation concentrates has long been considered an attractive possibility. The object of such a method is to produce electrolytic copper without resorting to expensive matte smelting and converting.
Electrolytic Recovery Of Copper And Zinc From Brass, D. H. Swank
Electrolytic Recovery Of Copper And Zinc From Brass, D. H. Swank
Bachelors Theses and Reports, 1928 - 1970
The purpose of this research was to continue the work of Thomas Parker, who worked on the recovery of copper and zinc from brass during the school year l934 - 1935. Since there is such a wide variety of brasses made with usually a third alloying constituent, remelted scrap is suitable only for castings of wide tolerance in specifications.
