From 2008 to 2015, China from a sodium cyanide importing countries, into the world's production, storage and export of highly toxic sodium cyanide country. This "first", how many people a little heart drums.
　　Why China will become the first big country of sodium cyanide.
　　What you don't know is that many of the downstream products of sodium cyanide are being eaten by you.
　　Because of the highly toxic nature, many of the deaths in history are related to cyanide. For example, computer science and artificial intelligence pioneer Alan Turing? EVA Hitler's mistress, Braun?. Nazi Germany during World War II also used cyanide to kill tens of thousands of Jews in concentration camps.
　　However, this is only the use of sodium cyanide in all the characteristics of a small point, in real life, to cyanide sodium as the representative of the use of cyanide, far more than these.
　　In fact, this "highly toxic" things are closely related to daily life, some of them still we will spend a large amount of money to put into the mouth, such as amino acids.
　　Represented by the synthesis of amino acid sodium cyanide, japan.
　　Japan is relatively early to join the country in the production of sodium cyanide. Although the international production of sodium cyanide in the United States, mainly in the United States (for example, DuPont accounted for 43% of total production capacity) and Western Europe, but Japan's Coca Cola and Cao DA and other four companies have also been to Japan, followed by Europe and the United states.
　　In 1999, the Japanese production of sodium cyanide 50% are used to produce methionine, methionine and mainly used for the production of feed.
　　Methionine is an important amino acid...... Amino acids? The familiar start right?
　　Yes, that's what we often hear in advertising and medicine. In the pharmaceutical industry, methionine is the main component of amino acid infusion and compound amino acid. In the health care products industry, methionine can be used for oral nutrition. In addition, biochemical research, photography, cosmetics and other fields have a shadow of methionine......
　　The alchemy of sodium cyanide
　　However, for sodium cyanide, these are not the ultimate big boss. On the present earth, the most important use of sodium cyanide is the extraction of gold.
　　Although very early human with sodium cyanide refining a variety of chemical and manufacturing pigments and travel home to kill them, but that when the output of sodium cyanide are not too big.
　　In 1887, people try to extract gold and silver with sodium cyanide.
　　This is to say that "love to cyanogen" and "iron", "gold" and "silver" with the characteristics of the. Like sodium cyanide into the human body, the cyanide ion will rapidly and Fe entanglement, iron ion transport of oxygen, cyanide can be sparse in ores of gold and silver to pull out, the quality is not high gold is particularly useful.
　　Since the development of this technology in the last century in 80s, the gold industry in all countries have a high ratio: 99.5% in South Africa, 88.1% in the United States, up to 84.9% in australia.
　　Now, 75% of the world's sodium cyanide is used for mining. In North America, South America, Russia, Central Asia, Australia, South Africa and China's gold mining industry, the vast majority of the consumption of sodium cyanide.
　　As the price of gold rose for sodium cyanide to extract gold prices have gone up. The international price of sodium cyanide, from the beginning of the twenty-first Century 1600 U.S. dollars / ton, rose to 2800 U.S. dollars / ton.
　　This has promoted the production of sodium cyanide in the world. Russia and Peru have ambitious expansion of an annual output of 4 tons of solid sodium cyanide production plant, but a rising giant soon to despise them.
　　China in the manufacture of sodium cyanide, it has made a number of advantages in the production of jeans, to the world to create a miracle of China's Sodium cyanide.
　　Where there is a large-scale production of sodium cyanide?
　　1960s, China started production of sodium cyanide, the initial production is Shanghai.
　　By 80s, with the development of the petrochemical industry, the demand for sodium cyanide began to increase rapidly. However, before 2008, China is still a net importer of sodium cyanide, 1-3 million tons per year to be imported.
　　In front of said that with the increasing demand for gold mining industry, the price surge in demand and prices at home and abroad under the dual stimulation, China's production of sodium cyanide fast increase. By 2009, China had become a net exporter of sodium cyanide.
　　According to the 2011, China a year production of sodium cyanide number close to 40 million tons. Now, China has become the world production of sodium cyanide in most countries, in addition to domestic use, every year there are more than 70000 tons for export.
　　In the process of rapid expansion of sodium cyanide industry, Hebei, Anhui have become a major province of sodium cyanide.
　　] according to data in 2011, the top ten enterprises of sodium cyanide production in China, Anhui and Hebei the an annual output of more than 10 million tons of large enterprises. Among them, the integrity of Hebei is the 700 tons of sodium cyanide in the accident producers
　　As a highly toxic chemical production industry, the State Council has issued a strict "chemical dangerous goods safety management regulations" to regulate. Arguably, the harm can be controlled.
　　But the more strict control of things, a loophole in the interests of the more attractive. Disturbing is that, in the actual operation, the storage, use and supervision of it, may be far from writing on paper so properly.
