Bacteria learned to turn poison into gold- VIDEO
Saturday, 06 October 2012 09:30


On the exhibition Prix Ars Electronica in Austria scientists Kazem Kashefi and Adam Brown of the University of Michigan showed an installation, that turns the poisonous venom-gold chloride into pure gold. According to Adam Brown, bacteria Cupriavidus metallidUrans are able not only to survive but to thrive in the highest concentrations of toxic poison-gold chloride, providing the pure gold in the form of sludge. This property of bacteria Cupriavidus metallidUrans was used in the construction of modern alchemy plant that Kazem Kashefi and Adam Brown called "The great deeds of metal fans", where just a week bacteria were able to process a few dozen liters of solution of gold chloride in several tens of grams of pure gold, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... urans.html

Extract gold from the sewage will be scientists - VIDEO

American scientists have proposed an innovative way of production of non-ferrous metals, in particular - gold. The fact that the trash is used to extract useful elements has long been known, but that the same extract useful elements from sewer water can - became known only now.

The scientific team from the University of Arizona studied wastewater in 94 US cities. A series of tests have found that the water every city there is a set of 50 different metals, among them such as platinum and gold. It is noteworthy that 50 of metals contained in the water each city, but in addition there were dozens more impurities depending on the local economic context.

Preliminary calculations show that if the extract gold from impurities, it can bring the US $ 13 million for every 1 million people in the country. Needless to today technology that would allow efficient extraction of gold from the slop water - no. However, this news is so inspired researchers at the University of Arizona, they opened a special branch is engaged in the study of this issue.

In fact, the value of the opening is not possible in mining precious metals. Removing all impurities from the water could improve the environment. The fact that the standard procedure for cleaning water reservoirs in urban piped water does not get rid of the metals.

As for the potential economic benefits, the removal of metal contaminants from the water could really help get a large amount of non-ferrous metals. Among the most valuable, even scientists have found in the water of some elements of rare earth metals, widely used in electronics. Removing them from the water, you can already today, but unfortunately, all the known methods of science and industry today is not economically profitable.

Gold and diamonds will end in 20 years - VIDEO

Within 20 years we will witness an acute shortage of many commodities. Write about this, analysts Goldman Sachs. According to their calculations, gold, diamonds and zinc remained just two decades, and the reserves of platinum, copper and nickel will not be enough for more than 40 years.

"The combination of two factors - a very low concentration of metals in the earth's crust and a very small number of really high-quality deposits - indicates that certain raw materials actually there are few" - wrote Eugene King, an analyst at the European division of Goldman Sachs in the sector industry.


Explored reserves of metals. Left-hand scale: absolute values. Right scale: how many years will be enough

He also noted that gold has more than 4 thoUSAnd. Years is a measure of wealth and even the ancient Egyptians understood that the metal is not only beautiful and brilliant, but also very rare.

"The relative scarcity and market confidence in the limitations of new fields will be the main driver of growth in the prices of these rare metals," - said the King. Moreover, experts predict that the peak of gold production will be reached this year, followed by a decline. By the way, that the peak of gold production will be in 2015, said the company is also in the forecast Goldcorp.



It should also be noted diamonds: their cost is mainly determined by just their rarity and, in the case of natural diamonds, uniqueness.

In general, the analysis of Mr. King may indeed be true, but only in the case of proven gold reserves actually start to decline. Then, of course, is already no matter what the amount of short positions in futures on gold, it will still go up in price, and fast enough and high. Another question - what would happen if suddenly miners find new deposits of "yellow metal". It also can not be excluded, and thus the forecast Goldman Sachs analyst is applicable only in part.

Generally, if the gold stocks really are depleted, it could trigger a real war for gold, and interest in fiatnym currencies will disappear.



Supply reduction - only one of the possible causes of the rising cost of gold. Experts voiced by others, such as Asian demand. It is Asia should become a locomotive for growth in gold prices. Australia & New Zealand Banking Group predicts that in the short term prices will remain at $ 1,100 per ounce. But then the growth of wealth in Asia, the growth of investments and actions of central banks in emerging markets will lead to increased demand. If the movement towards a more open China's economy will be problematic and the global financial turmoil continues, prices could rise to $ 3.23 kyr.

Traditionally in Asia, people buy jewelry with an increase in wealth, and in some countries the attractiveness and popularity of gold due to cultural aspects. $ 2 thoUSAnd. Prices strikes in the next decade. In Australia & New Zealand Banking Group estimate the probability of this event in 45%.
