Production statistics minerals

United States Geological Survey. Minerals Yearbook Volume I—Metals and Minerals. Background information and production statistics on various mineral compounds such as soda ash, salt, gypsum, etc. 

Boron never occurs as a free element but always as a compound. The most common minerals of boron are borax, or sodium borate (Na2B407) kernite (another form of sodium borate) colemanite, or calcium borate (Ca2B< Oii) and ulexite, or sodium calcium borate (NaCaB509). These minerals usually occur as white crystalline deposits in desert areas. As of 2008, Turkey was the largest producer of boron ore. Other major producers of boron materials are Argentina, Chile, Russia, China, Bolivia, and Kazakhstan. Production statistics for the United States were not released in order to protect trade secrets. 

Revista de estadistica, monthly, 1938-. Supersedes Revista de economia y estadistica, 1933-36. Statistical review. Principal economic data on production (agricultural, mineral and metal, electrical energy, and industrial), prices and cost of living, foreign trade, finance, and transportation. In LC. 

The development of newer techniques (chromatography, thermodiffusion) for the separation of the different groups of hydrocarbons from mineral oil fractions allows a better characterization of such type-concentrates with the aid of physical constants. Combination of physical methods of separation with the statistical analysis of the products obtained, may lead to a more detailed and more complete knowledge of the composition of oils. 

In reactions involving unsymmetrical diaryltetrazenes such as 238 four different products arise as a result of this statistical decomposition (equation 128). Horwitz and Grakauskas have discussed the mechanism of coupling between phenylhydrazine and benzenediazonium salts in detail. In mineral acid, little or no free base is present and the reaction should involve either, or both, of... 

The Bureau of Mines likewise issues the Minerals Yearbooks (in 3 volumes) which contain official government statistics on production and distribution of metals, minerals, and mineral fuels. They also include factual accounts of economic and technologic developments and trends. Entire yearbooks and separate...

Does not include natural sodium carbonate, except for the U.S. for 1990 and 2000, when the total production was from natural sources (Table 7.3). Data calculated from Minerals Yearbooks [24] and from U.N. Statistical Yearbooks [25]. 

The Bureau of Mines is a source of many chemical statistics. The monthly Coke and Coal Chemicals report, part of the bureau s Mineral Industry Surveys, contains, in addition to data on oven and beehive coke production, figures on production of ammonium sulfate, ammonia liquor, naphthalene, benzene, toluene, xylene, solvent naphtha, pyridine, crude coal tar, and cresote oil. Sales and end-of-month stock figures are also shown in the report. A useful feature of the report is the year-end supplement which gives year s totals by months. 

An official monthly bulletin gives statistics on population, agriculture, forests and fisheries, industry (production indexes for main branches, output figures for salt, minerals. 

Manufacturing Chemists Association, Washington, D. C., Chemical Facts and Figures, 1941, 1946, and 1950. Production, sales, sales value, prices and price indexes, and foreign trade of chemicals and allied products. Includes Canadian chemical and mineral statistics. 

Spill statistics are collected by a number of agencies in Canada and the United States. In Canada, provincial offices collect data and Environment Canada maintains a database of spills. In the United States, the Coast Guard maintains a database of spills into navigable waters, while state agencies keep statistics on spills on land that are sometimes gathered into national statistics. The Minerals Management Service (MMS) in the United States maintains records of spills from offshore exploration and production activities. 

Many lead-containing products, including leaded glass, can be recycled and provide another source of material to supplement the naturally occurring minerals. The processing required to produce metallic lead and lead oxides are outlined in Sect. 3. Descriptions of the most important sources of lead and statistics on lead production and consumption are also presented. 

This section contains descriptions of a cross-section of the workflow-based tools designed to manage computations in the discovery arena. This is not an exhaustive list of such products, or even of just those with a life science focus. In addition, although there are interesting workflow tools focused on modeling and statistical analysis, they are beyond the scope of this chapter (e.g., the Clementine workbench from SPSS [DM1] and Insightful Miner from Insightful Corp. [DM2]). 

All estimates for particle production due to forest fires and biomass burnings are based on experimental emission factors combined with statistical data for the global consumption rates for the materials involved. The most detailed study has been made by Seiler and Crutzen (1980). They deduced a particle production rate from forest fires alone of 100 Tg/yr. Including agricultural biomass burnings raises the rate to about 200 Tg/yr, a value approaching that for mineral dust emissions. This is much higher than all earlier estimates. 

In statistical tables of mineral production, potash and K2O equivalents are listed, but in fact refer to soluble potassium salts. (Strictly, potash refers only to KOH.) World production of potash rose from 0.32 Mt in 1900 to >30 Mt in 2000, with the major producers being Canada and the former Soviet Union, followed by Germany. Major...
