Bell mine

The Silver Bell Mine is located thirty-five miles northwest of Tucson, at an elevation from 2,500 to 3,000ft. The mine consists of four open-pits and is located on 19,000 acres of land (Titley 1994). 

The Silver Bell Mine area consists of dipping units that are composed of dacite porphyry, alaskite and monazite. The rock ages span the Paleozoic, Mesozoic and Cenozoic periods. The Paleozoic wall rocks consist of quartzite, siltstone and altered limestone. The carbonate rocks are exposed along the contact between the host rock and intrusions, and host the...

I was working at Bell Telephone Laboratories at that time. Much of the radar development came out of applied work in industrial laboratories, and so did microwave spectroscopy. I persuaded the Bell Laboratories to let me do microwave spectroscopy, and so it started at Bell Labs, but it also started at General Electric, where a friend of mine began it. He did a little bit of work, but then the General Electric people said, no, you must stop, it s not going to have any use for us, we have no applications. So this work had to stop at General Electric. At RCA, another important electrical company, a friend of mine started it there, and he worked on it for a while, and the company said, no, that s of no value to us, we won t pay you anything for it, you must stop. 

Mine was a technical resume of what we hoped to prove. When it was finished, I got one glance at the staS before the press crowded along the rail. Belle Mayer was looking into space then she looked over at Sprecher, who was watching her. Tears were rolling down her face. They smiled at each other. 

For example, Levson (2001) reports anomalous Cu values in the <0.063 mm till fraction up to 4 km down-ice from the Bell Cu-Au mine. In these trains, metal values typically decreased exponentially in the down-ice direction (Klassen 2001). 

The Renison Bell tin mine is a large, but complex, oxide mineral deposit. Renison ore consists largely of pyrrhotite, quartz, dolomite, siderite and dorite. The chemical composition of the iron varies considerably. Some of the ore types are high in copper and silver. Table 21.5 shows the chemical analyses of various ore types.

It was believed that the mine was designed for anti-invasion purposes to be placed in shallow water against landing craft, vehicles and tanks Type JG Antiboat Land Mine, which existed in 5 modifications, each being actuated by a single chemical horn screwed into the top. The mines were either bell-shaped or of a truncated cone. Each contd 22 lbs of Type 98 Explosive. The mines were fired when chemical horns were broken (pp 222-23, Fig 168)...

For short distances front the mine, transportation is hy truck or conveyer bell. Rail transportation is generally used for greater distances. Slurry pipelines are being considered as an alternative. Drying can be accomplished by evaporative, hydrothermal, nr other thermal processes.

MCS patients are sometimes called canaries, because MCS patients can function as early warning signals. Early miners would take canaries down into the mine shafts because canaries fell from their perches rather quickly when carbon monoxide or other dangerous gases arose. Miners made sure they got out as soon as this happened. MCS patients are thus actually the canaries of this day and age, since they become ill from chemical substances in low doses, especially synthetic chemical substances, from which others do not (yet) get sick. They therefore also function as an alarm bell, although this bell is not heard as it should be. 

In the case of lead arsenate (acid form), calcium arsenate, and sodium arsenate, the Pb-isotopic compositions closely match those of sulfides from porphyry copper deposits from southeastern Arizona, specifically from the Pima and Silver Bell districts (Bouse et al., 1999). Notably, other major historical producers of arsenic trioxide (e.g., Anaconda Copper Co., US Smelting Co., Jardine Mining Co.) used...

It is likely that at least back to 3,500 Ma the principal environmental acid driving this hydrolytic reaction was carbonic acid dissolved in rain water and groundwater (Holland, 1984), as is the case in soils today (Nahon, 1991). Much soil CO2 may also have come from respiring organisms, which also could have contributed organic acids. Nitric and sulfuric acid may have been locally important in soils developed on particular parent materials, but nitrogen and sulfur salts are so far unreported in Precambrian paleosols, unlike modem soils of mine dumps (Borden, 2001), and hypothesized modem soils on Mars (Bell, 1996 Farquhar et al, 2002), and Venus (Barsukov et al, 1982 Basilevsky et al., 1985).
