South Africa industry

Natural diamonds are found in kimberlite of ancient volcanic "pipes," found in South Africa, Arkansas, and elsewhere. Diamonds are now also being recovered from the ocean floor off the Cape of Good Hope. About 30% of all industrial diamonds used in the U.S. are now made synthetically. 

Worldwide furfuryl alcohol capacity in 1993 was estimated to be 110,000 metric tons (38). As with furfural, new capacity in developing countries is replacing older capacity in developed countries. China and South Africa have become significant producers of furfuryl alcohol. New plants have been built in Asia and Indonesia as well. Consumption of furfuryl alcohol is spread over the globe the largest use is in the foundry industry which is increasingly moving away from heavily industrialized countries. 

Auckland Regional Authority converted two M.A.N. buses to use a cetane improver and methanol and South Africa investigated the use of methanol with a proprietary cetane improver. Eour Renault buses were converted in Tours, Erance to operate on ethanol and a cetane improver, Avocet, manufactured by Imperial Chemical Industries (ICI). The results of these demonstrations were also technically successfiil slightly better fuel economy was obtained on an energy basis and durabiUty issues were much less than the earlier tests using dedicated engines. 

In 1984, the Ube Ammonia Industry Co. began operating the largest Texaco coal gasification complex to date. This faciUty is located in Ube City, Japan, and has a rated gasification capacity of 1500 t/day of coal, and production capacity of 1000 t/day of ammonia. The plant has successfully gasified coals from Canada, AustraUa, South Africa, and China. At the present time the plant uses a mixture of petroleum coke and coal (43). 

Imperial Chemical Industries (ICI) operated a coal hydrogenation plant at a pressure of 20 MPa (2900 psi) and a temperature of 400—500°C to produce Hquid hydrocarbon fuel from 1935 to the outbreak of World War II. As many as 12 such plants operated in Germany during World War II to make the country less dependent on petroleum from natural sources but the process was discontinued when hostihties ceased (see Coal conversion PROCESSES,liquefaction). Currentiy the Fisher-Tropsch process is being used at the Sasol plants in South Africa to convert synthesis gas into largely ahphatic hydrocarbons at 10—20 MPa and about 400°C to supply 70% of the fuel needed for transportation. 

Ilmenite is more abundant than mtile. Ilmenite world suppHes are estimated to meet the requirements of the Ti02 industry into the twenty-second century. The largest sources of ilmenite are in AustraHa, Canada, South Africa, Russia, and the United States. Large, unexplored sources also exist in China. About 9 million metric tons of ilmenite are mined aimuaHy. Long-term atmospheric effects weather ilmenite into leucoxene [1358-95-8], which contains most of its iron as Fe " . The majority of the world s supply of mtile comes from the beach sands of AustraHa, Florida, India, Bra2H, and South Africa. The total worldwide supply is estimated to be about 50 million metric tons. About 0.5 million tons are mined a year. The supply should last at least until the end of the twenty-first century. 

The evolution in the world production of asbestos fibers since 1950 is illustrated in Table 5 (5) after a peak near 1980, production leveled off after 1985 at 4.2 4.3 X 10 t. Changes in the production of the two main producers, Canada and the former USSR, over the same period are also illustrated. These figures show a substantial decrease in the Canadian production with a concomitant increase in the former USSR production. During recent years, several other countries, namely Brazil, Zimbabwe, and China, have substantially increased their production of chrysotile. Most of China s production, as well as the limited production of many other countries, is used in local industrial appHcations. South Africa is the only country where the three main types of asbestos are produced (chrysotile, crocidoHte, and amosite), and the only significant producer of amphibole fibers.

Economic Aspects. U.S. production statistics for the period 1980 to 1988 are given ia Table 4 (220). Exports amount to ca 20% of annual United States production, and imports amount to almost 10% of domestic production. The main foreign producers are Japan, South Africa, and Canada. South Korea, Brazil, and The People s RepubHc of China are minor producers. Japan s Nippon Soda Co., Ltd. is the world s third largest producer. Two other Japanese producers are Toyo Soda Co., Ltd., and Nankai Chemical Industry, Ltd. 

Imperial Chemical Industries in Great Britain hydrogenated coal to produce gasoline until the start of World War II. The process then operated on creosote middle oil until 1958. As of this writing none of these plants is being used to make Hquid fuels for economic reasons. The present prices of coal and hydrogen from coal have not made synthetic Hquid fuels competitive. Exceptions are those cases, as in South Africa, where there is availabiHty of cheap coal, and fuel Hquids are very important. 

Natural diamonds used for jewellery and for industrial purposes have been mined for centuries. The principal diamond mining centres are in Zaire, Russia, The Republic of South Africa, and Botswana. Synthetic diamonds are made by dissolving graphite in metals and crystallising diamonds at high pressure (12-15 GPa) and temperatures in the range 1500-2000 K [6] see section 3. More recently, polycrystalline diamond films have been made at low pressures by... 

Tannin adhesives are the class of modified natural adhesives which are used and have been used industrially for more than 25 years, mainly in South Africa and Australia, but also in Zimbabwe, Chile, Argentina, Brazil and New Zealand. It is mainly the still limited raw material supply that limits their use to approximately 30,000 tons resin solids per year [16,17].

Let me not forget the mention of those who have provided fuel for my research vehicle to propel to the fore - the financial sponsors. Predominant among these are Dr Sibisi, the President and CEO of the Council for Scientific and Industrial Research (CSIR), Mr. Cyril Gamede, the Operations Director of African Explosives Limited (AEL) and Mr. Leon Kruger, the Operations Director of Johnson and Johnson (Pty) Ltd. My heartfelt thanks also go to the Water Research Commission (WRC) of South Africa. 

This collector has the formula shown in Figure 21.3. The identification of /7-tolyl arsonic acid as a selective collector for cassiterite flotation led to the introduction of this collector into many industrial plants. The first recorded industrial use of /7-tolyl arsonic acid was at the Alterberg mine in Germany. By the early 1970s, this collector was introduced into a number of operations, including Rooiberg and Union Tin (South Africa), the Renison and Cleveland tin mines (Australia). 

Of the 25% share of coal in world primary energy supply, hard coal makes up around 90% (BGR, 2007). Owing to its high calorific value, the main use of hard coal is for electricity generation (60% of world hard coal production), 16% is used for steel making, and the rest in other industries and households. While in the EU25 around one third of the electricity is produced by (hard) coal, this share amounts to 50% in the United States, 70% in India, 80% in China, 85% in Australia, 90% in South Africa and 93% in Poland. 

Benzene from coal coking started to become less important in the 1950s as the benzene market mushroomed considerably faster than the steel market, and the marginal supply of benzene came from petroleum refining. Coal-based benzene for the U.S. chemical industry dropped from nearly 100% in 1955 to 50% in the 1960s and less than 5% after the 1980s. Coal-based economies like South Africa and New Zealand sail rely considerably more on coal-derived benzene. 

In South Africa traditional or home-made products are more commonly used in rural areas while products manufactured by small cottage industries are dominant in urban areas. One of the small smokeless industries was bought by Swedish Match in 1999 and they ve continued to manufacture the same products used for both oral and nasal application. Unlike many other countries, nasal use predominates among the 13.2% of black women in South Africa who use smokeless tobacco, 80% nasally and 20% orally. Overall usage is approximately 10%, but reaches 18.6% among black children (Ayo-Yusuf et al. 2004). Only about 1% of South African men use snuff (Ayo-Yusuf et al. 2008).
