Oxygen Enriched Atmosphere Roasting, Clarence Wells Jr
Oxygen Enriched Atmosphere Roasting, Clarence Wells Jr
Bachelors Theses and Reports, 1928 - 1970
The possible benefits of oxygen enriched atmosphere roasting have been known to metallurgists for many years, but only since the development of equipment and processes to produce cheap oxygen in very large amounts has much serious consideration been given this matter.
Age Hardening Of Silver-Platinum Alloys, Robert A. Wilson
Age Hardening Of Silver-Platinum Alloys, Robert A. Wilson
Bachelors Theses and Reports, 1928 - 1970
The alloy system selected for study was the binary alloy of platinum and silver. An examination of the various silver alloy diagrams revealed that of several possible alloys, the silver platinum was the most suitable with regard to solubility.
The Inhibitory Effects Of Carbonaceous Materials On The Cyaniding Of Gold Ores., David Currie Jr.
The Inhibitory Effects Of Carbonaceous Materials On The Cyaniding Of Gold Ores., David Currie Jr.
Bachelors Theses and Reports, 1928 - 1970
Carbon and carbonaceous material have been known to have a deleterious effect upon the cyanidation of gold and silver ores since the very beginning of the process. Organic matter is a common source of impurities in cyanide solution, its reducing effect being notorious.
A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook
A Study Of The Effect Of Oxygen On The Rate Of Dissolution Of Gold In Cyanide Solutions., John A. Cook
Bachelors Theses and Reports, 1928 - 1970
The accepted chemical reactions in the dissolution of gold by cyanide solutions require the presence of gold, cyanide, water, and oxygen. The importance of dissolved oxygen in cyanide solutions as a factor is recognized by those familiar with cyanidation. Manufacturers of cyanidation equipment realize the necessity of oxygen, as shown by the appliances they have developed which are attached to the agitators in order to saturate the cyanide solutions with air.
