MetALLOGRAPHIC investigations of composites of zinc alloys and aluminum have been made to study the effects of various thermal treatments on the zinc-alloy grain size and diffusion of zinc into the core material. The use of various alloys of zinc has necessitated the development of a universal etchant which will allow microscopic examination of the zinc grain size regardless of the composition.

US 4,190,434 - In the thermal production of magnesium metal, a mixture of calcined dolomite, an iron- silicon-aluminum alloy as a reductant, and residual slag from the production of ferrochromium is smelted to evolve magnesium vapor, which is then condensed. The use of bauxite is lessened or eliminated because of the relatively high alumina content of the residual slag. R. Bonfils, A. Mena, C. Payn, and L. Septier, assigned to Ste. Francaise d’Electrometallurgie (SOFREM). Feb. 26, 1980. 6 pp. (75-10R). Filed: 6-14-78 (915,387). Priority: France, 6-24-77 (77/20,227).

The effects of capital, operating and debt cost variations on project performance criteria are examined using a theoretical model and an actual case history. On an after-tax basis, financial measurements are found to be most sensitive to operating cost changes, somewhat sensitive to reasonable changes in capital costs and relatively insensitive to interest rate fluctuations.

WHEN the atomic age broke suddenly upon the world in 1945 with all its terrible implications, predictions concerning the future of atomic energy were as numerous as columnists and often inflated. Today, some seven years since the explosion and probably ten since the Government took over development of nuclear energy, the impact on our way of living has been largely political (except of course for the thousands of people who have become employed in the AEC). Considering the world situation, weapons have come first naturally. But credible progress in the plow-share uses of nuclear energy-medicine, agriculture, power-can also be noted.

The current status of the US lead and zinc industries was reviewed by J. G. McCullough, president of Amax Lead and Zinc Inc. He reported that in the US, lead and zinc are separate industries because of the nature of mineralization. The large Mississippi-type zinc deposits are practically lead-free, and while the new lead belt in Missouri has some zinc content, it does not have the same favorable economic impact as in the complex massive sulfide ore bodies being developed elsewhere.

First actual production of titanium metal at the newly constructed Henderson, Nev., plant of Titanium Metals Corp. of America occurred in mid-October. Production will be expanded rapidly until the initial goal of 10-tons per day is reached. This will be equivalent to eight times the present world production of titanium metal. W. Eberstady & Co., New York City, has announced plans for construction of a $400 million plant for the manufacture of synthetic liquid fuels from coal in southern Illinois, if the Government will guarantee a minimum price for the gasoline and other products to be produced.

Largely forgotten by today's environmentalists and mineralogists is a pioneer scientist of the nineteenth century named Ellen Swallow. Fortunately, the memory of her accomplishments has been resurrected by Robert Clarke in his biography, Ellen Swallow: The Woman Who Founded Ecology. Her direct contributions to the field of mining included authoring First Lessons in Minerals and an analysis of the rare mineral samarskite which indicated the presence of an insoluble residue; her findings led to the eventual discovery of samarium and gadolinium. While enjoying the distinction of being the first woman student at the Massachusetts Institute of Technology, she successfully isolated vanadium in an ore which other experts had examined without detecting the metal.

A STUDY of copper and silver base alloys was made with the object of finding, if possible, useful alloys subject to dispersion hardening. These studies led to the discovery of several alloys showing considerable dispersion hardening, the most important of which, the alloys of copper with iron, nickel, cobalt and chromium silicides, have since been very ably reported by M. G. Corson.1 This paper is offered as a few notes covering alloys other than those described by Corson and some further data on the silicide alloys.

Rich Hill is situated in the famous car-wheel iron region of Southwestern Virginia, and although it contains many iron ores, this paper will be devoted chiefly to its car-wheel ore. Geologically, Rich Hill is somewhat difficult to describe, as the strata of the region are seriously folded and contorted. It lies at the base of one of the primordial spurs of the Blue Ridge, the ore appearing as a sedimentary deposit on the limestone No. 2, sometimes showing an imperfect stratification, but generally being an

Extended discussions, by inviting attention to problems affecting the conservation of natural resources, have encouraged investigations as to their sufficiency, with the general result that the more thorough the examination, the less cause appears for anxiety as to the exhaustion or serious depletion of these resources.
