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.

It is the purpose of this investigation to obtain some insight into optimum conditions for leaching Stibnite with sodium hydroxide solution and also to steady the factors affecting the electrolysis of the resulting solution.

The reclamation of metals from scrap is becoming increasingly important in the metallurgical industry. Copper, because it does not corrode readily and is electronegative to most common metals, is peculiarly adapted to reclamation.

The production of metallic manganese by electrolysis is of potential value for the recovery of this strategic metal from domestic deposits. These deposits are largely unsuitable for the production of ferromanganese, but they are amenable to low-cost leaching processes.

Several methods have been investigated, with some success, for treating scrap brass to recover copper and zinc, either as pure metals or as salts of the metals. One of the more promising of these methods is electrolysis in sulfate solution for the recovery of pure copper and zinc.

The contents of this paper represent attempts to deposit the metal, manganese from sodium manganate solutions. The source of manganese was limited to the nodulized product from roasting rhodochrosite and was therefore chiefly manganese oxide.

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.

In the copper electrolytic refining operation, two main objectives are desired: the first is the production of a metal of desired chemical composition and physical characteristics, and the second is the recovery of the valuable by-products.

Almost everyone is familiar with the tremendous importance of copper in our everyday life. One of the properties of copper which determines its great usefulness to mankind is its electrical conductivity. This property alone has more to do with the prominence of copper among useful metals then does any other.

The electrolytic refining process, while usually considered an auxiliary process used in conjunction with pyrometallurgical extraction, deserves a special niche in the complex metallurgy of copper. The development of electrolytic copper refining, for example, is largely responsible for the prominence of the electrical industry. Conversely, it could be stated that the electrical industry played an important part in the development of the copper industry.
