Download or read book Living Superior, Arizona, from 1930 to 1950 written by Joaquin Trujillo and published by Zeta Books. This book was released on with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book tells the history of Superior, Arizona, from the years 1930 to 1950. Superior is located in the central part of the state just inside the southern boundary of the Tonto National Forest. The town was the home of the Magma mine, which was owned by the Magma Copper Company. The Magma mine was an underground, or “hard rock,” copper mine. It operated continuously from 1910 to 1982, was one of the most productive mines in US history, and also included a smelter, mill, and railroad. The book hermeneutically (interpretively) merges into a single narrative the oral histories of 15 persons who were born between 1923 and 1934 and lived in Superior during all or most of 1930 through 1950. The purpose of combining the contributions into a single story was to yield a thicker, more corroborated history of the town than otherwise would have been possible by presenting them separately. Supplementing the narrative are a (1) historiographical description of the town and mine, (2) sociological analysis of their relationship, the community’s solidarity, and the segregation experienced among Mexican, Caucasian, Native American, and African American residents, (3) description of the personal meaning of underground mining, and (4) review of methods.

Download or read book Recovery of Rutile from a Porphyry Copper Tailings Sample written by T. O. Llewellyn and published by . This book was released on 1980 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Bureau of Mines conducted batch-scale tests on a sample of parphyry copper mill tailings as part of a study to determine the feasibility of rutile recovery from this source. The tailings that were tested contained 0.75 percent titanium dioxide (Ti02), with about two-thirds of the Ti02 values occurring as rutile. Mineralogical studies indicated that about one-half of the Ti02 content could be considered recoverable. Beneficiation studies of the tailings showed that best flotation results were obtained when sulfides and carbonates were removed by bulk flotation prior to rutile flotation. Rutile flotation was most effective when a petroleum sulfonate collector was used in an acid circuit. From this basic method of flotation, two alternative procedures were developed. The first procedure was to size and grind the tailings to minus 200 mesh; deslime the total pulp; and then float the sulfides, carbonates, and rutile. The second procedure was the same, except that it did not include sizing and grinding. Flotation of the sized and ground tailings yielded rutile concentrates containing 43.1 percent Ti02 and 75.7 percent of the recoverable Ti02. Rutile concentrates floated from the tailings that were deslimed but not ground contained only 34.7 percent Ti02 and 69.4 percent of the recoverable Ti02.

Available in PDF, EPUB and Kindle. Book excerpt: 1.1 The Importance of Copper Copper, the red metal, has been known in histor~ for thousands of ~ears. It ma~ have been mankind's first metal (Joralemon= 1973). And still, probabl~ more than one hundred decades after native copper was used for the first time (Muhl~ (1973: 171», toda~, copper is a ver~ important commodit~: 1. Onl~ aluminum (first in 1963) surpasses refined copper in terms of the total 1 world's mine production and consumption. It outpaces zinc, lead, nickel and tin • 2. Refined copper is one of the most important export products of the developing countries. In 1975, refined copper ranked 8th in the developing countries' export values in general, it was 6th among their non-fuel exports, and their most important export 2 commodit~ among the non-ferrous metals • 3. Man~ small and medium sized industrialized countries depend heavil~ on copper imports. For example, West German~'s share in world mine production has alwa~s been smaller than 0.1 per cent. In the last few decades, however, the Federal Republic's consumption share has amounted to some 8 i. in 1982. 4. Copper is of utmost importance for the export earnings of several countries.
