Quite recently yet, about 10-12 years ago, the educated
part of Tajikistan population was inclined to think that on
gaining independence the country will do a colossal leap in
its economic development at the cost of natural resources
reclamation. This mania was inherent mainly in intellectuals
engaged in creative labor. And many newspapers retorting them
got used to reiterate as an argument a dictum which came into
a proverb in society setting our teeth on edge: “Our mountains
have all Mendeleyev’s table in its entrails”. Partially, of
course, this theory is explained by patriotism, an aspiration
to get rid of cotton as monocrop. But many scientists in mining
and economics were puzzled with this assertion. Among them
there is Edward Gusakov, Merited engineer of Tajikistan, bearer
of “Miner’s Glory” decorations of three degrees, chief engineer
of “Vostokredmet” State-owned enterprise (SOE).
WHAT ISURANIUM?
Chemical symbol U, specific weight - 18.7 g/cm3. Melting temperature
- 1132C.
Uranium was discovered in 1789 in nasturanium mineral. It
is called after Uranus planet discovered eight years earlier.
It was supposedly about 6.6 billion years ago. It is a heavy
(dense) metal containing in abundance concentrated energy.
Its radioactive disintegration is the basic source of therm
inside the earth causing convection and drift of continents,
whereas in the solar system there are no such things.
Natural uranium occurs in the earth-crust, chiefly in the
mixture of two isotopes: uranium - 238 (U-238) - about 93.3%
and U-235 - about 0.7%. Isotope U-235 splits easily under
certain conditions liberating a great deal of power. That’s
why it is said being “divisional”.
U-238 disintegrates very slowly, the period of its semi-disintegration
is equal to the age of the Earth.
- This opinion belongs basically to amateurs
from mining and economics, - says my interlocutor who devoted
half of his life to the elaboration of uranium production
technologies in Tajikistan. - It is difficult to count even
by means of a calculator the expenses beset with ore extraction
in the mountains of Tajikistan. And it is without the means
bound to be spent for tapping reserves, drafting documentation,
involvement of technique, labor force and even transportation
of raw stuffs along precipitous mountains. Pay attention to
the regular phenomenon: a rare firm would be interested in
investing resources into non-ferrous metals extraction; even
coal, so popular under mountainous conditions, being not attractive
for others. Visiting multiple times remote villages I heard
rebukes from local inhabitants, why you, dealing with uranium
can’t reinforce the defense capacity of Tajikistan? Yes, we
do have uranium deposits in the country. But I realized, one
should conduct a frank confidential talk with elders and teachers.
And we parted after a substantial conversation being pleased
with each other…
Uranium ore deposits are known in the world for hundreds of
years. But as for industrial use of uranium and its salt it
started in 1853 when they were applied as additions in glass
production. When the phenomenon of radioactivity had been
discovered uranium ores turned into a source of radium for
scientific-research aims. Uranium-radium industry developed
mostly by 1939 when the problem of uranium atomic nucleus
splitting as solved. Intensive extraction was carried out
in the USA, Canada, Belgian Congo. And in the USSR the history
of uranium ores extraction began in Tajikistan in 1926 when
Taboshar deposit was discovered. “In 1930-31 Giredmet (State
Institute of Rare Metals) conducted explorations on extraction
of radium from ores, - well-known expert in atoms Arkady Kruglov
writes in his book “How Atomic Industry Was Built up in the
USSR. - In 1935 they set up a small settlement, a mine and
a hydro-metallurgic plant”. In 1941 the plant subordinated
to the Head Management of rare metals under Narkomtsvetmet
(people’s commissariat on non-ferrous metals) was evacuated
to Taboshar settlement. In 1934 radium was extracted from
Taboshar ore. Uranium deposits were found also in Adrasman
and Mailisoo. On that raw stuffs base they started to erect
combine #6 (now “Vostokredmet” SOE). The reserves of industrial
uranium in Tajikistan were limited to the mid-1950s the entrails
were exhausted. Doomed almost to extinction the method mining-chemical
combine revived had been engrafted on the deposits of Kazakhstan
and Uzbekistan. To say the truth, yet in the 80s some amounts
of raw stuffs were given by Taboshar and “Right Bank” mine
in the vicinity of Khujand. Here they carried into effect
experimental-industrial jobs on lixiviation of uranium heaps
from undressed ores; hereby mining-slitting method when uranium
was leached directly on the spots of ore beddings was tested.
- Intensified geological reconnaissance revealed several uranium
ore provinces - Mogoltau-Karamazar, Hissar-Karatega, and Pamirs
- Edward Grigoryevich goes on; for the elaboration of the
methods of underground lixiviation he was awarded the premiums
of the USSR council of ministers and the republican one. -
Regretfully, uranium reserves in ore are too scanty, so industrial
activity dealing with these deposits is economically non-expedient.
It just refers to Mendeleyev’s table in the mountains of Tajikistan.
The share of “Tajik” uranium in the total amount of that one
which is extracted and processed by “Vostokredmet” SOE is
about 5%. The rest was brought from other republics. But it
is not the quantity that counts - namely Tajikistan was that
testing ground where they worked out the method of uranium
extraction from different types of deposits; new technologies
of ore processing later on being successfully used by other
outfits.
The book “Uranium Deposits of Tajikistan” written by the experts
of our combine will be of interest for those who wish the
know about the history of uranium industry of the republic.
Unfortunately, tapping, reconnaissance, extraction and processing
of uranium ores were performed under the veil of strict secrecy
due to the conditions of their time and therefore the wide
circles of professionals are not knowledgeable for these developments,
the preface to the book runs. The secrecy of the information
dealing with uranium thematics produced a big gap in the knowledge
of the predominant part of the graduates of higher schools
whose bias dealt with mining geology and chemical technology.
You can call it no otherwise than a paradox when the geology
circles of Tajikistan, the republic which gave the first uranium,
are up to now unaware of basic regularities of the geological
structure and allocation of uranium deposits, methods of ores
elaboration and processing; and the main thing is the ignorance
concerned with the resultative ecology. This unawareness pours
judgments influencing in the negative public opinion. Practically,
this book has been the first step towards a liquidation of
the informational vacuum shaped.
Today uranium is chiefly applied as fuel for atomic power
engineering. Over 16% world electric power is produced by
more than 440 nuclear reactors; over 30 reactors are being
built.
- And still the amount of uranium extracted for today is almost
twice less than all the functioning reactors need, - tells
the chief of the productive-technical section under “Vostokredmet”
A. Botov. - It is imputed to the production process of bygone
twenty years when stored reserves and “military” uranium assigned
for nuclear weapon were in the foreground. But these reserves
are depleted and analysts prognosticated both uranium production
growth and prices rise for the oncoming years. The full cost
of one worked out kilowatt/hour of electric power (capital
expenses inclusive) at the electro-stations of the world vacillates
in the range of 3-5 cents. The value of energy obtained at
the electro-stations of other types is approximately in the
same limits. The advantage of atomic power engineering lies
in little expenditures for fuel - from 5% to 9% from total
ones. But the latters make up no less than 50% at the electro-stations
working on coal, oil, gas. A kilogram of natural uranium is
equivalent by the power obtained to 10 tons of oil or 15 tons
of coal; a kilogram of dressed uranium - to the amounts being
8 times higher.
The tapped reserves of uranium in the world are fairly huge
- of about 2000-2500 thousand tons. But many deposits are
not worked off due to extraordinarily high expenses for extraction.
Among CIS countries the primary producers of uranium for today
there remain Russia, Uzbekistan and Kazakhstan. Hereby, in
Russia uranium is expensive, raw stuff base is depleted, tapping
of known ore beddings will require a lot of time and uphill
work. Uzbekistan is hardly imagined to accrue the volumes
of production in the nearest years as it is beset with immense
capital investments. But as for Kazakhstan, it’s a peculiar
article. This country possesses the third tapped reserves
of uranium in the world, and “cheap” one into the bargain.
“Kazatomprom” (atomic industry) national company is developing
dynamically having excellent vistas for the future. It’s not
by chance that such biggest world-known uranium companies
as “Kozhema’ and “Catco” launched joint ventures with “Kazatomprom”
NAC. There are other investors as well. And what about former
companions? In 1997 the heads of CIS countries ratified the
Plan of CIS states cooperation development in peaceful employment
of atomic energy: a financial-industrial team on extraction
and processing of uranium - containing raw stuffs was supposed
to be formed, all enterprises and organizations of Russia,
Kazakhstan and Tajikistan were to be involved. In 2001 such
JV was launched on the base of “Zarechnoye” (means behind
the river) deposit, but instead of Tajik “Vostokredmet” Kyrgyz
JSC “Kara-Bolta Mining Combine” was included. “Vostokredmet”
was promised to be admitted to the next joint venture. But
when will this time have come? Soon “Zarechnoye” JV will mark
its second anniversary, but they didn’t actually proceed to
uranium extraction that seems to be accounted for by lack
of resources.
Taking into consideration the tendencies of power engineering
development one can say for sure that the world uranium market
one of the most stable, lucrative and attractive for investors
in the course of many decades. Integration into the world
economy, consolidation of links with far abroad are necessary,
of course. Every sovereign state has a right to independently
choose business-partners. But it would be a very sad thing
if only odds and ends form the Kazakh uranium cake fall to
the lot of former companions.
April in Tajikistan is rich in international political and
economic events - CIS countries foreign ministries council,
EurAsEC and CSTO summits. It is worth anticipating any changes
in the interrelations with former companions on the Ministry
of middle-sized machine-building of the USSR, now “Minatom”
of Russia? I think still we should hope.
Power can be considered in two categories
- primary and secondary.
The primary power includes such kinds of natural resources
as soft wood, coal, oil, natural gas and uranium, energy of
wind, sun and hydro-energy. The secondary power embraces the
forms being more fit for exploitation, affording to be transformed
into their state by the primary power, such as electric energy
and benzene.
The primary power can be resumable and non-resumable. Resumable
power is the energy of sun, wind, waves, biomass (soft wood
or plants), geothermal and hydropower.
Non-resumable power refers to organic fuel: coal, oil, natural
gas giving over 80% of energy for today. Plus uranium.
There is no deficiency in the primary power. Sun gives us
its energy every day. We see its evincement in various forms.
Thus, for example, trees and plants being pierced with sun
rays transform this power into a vegetative biomass. The enormous
amount of solar power accumulated in the earth-crust. Uranium
is also a source of power. It had formed in the Earth entrails
billions of years ago even before the solar system came into
being.
The principal goal for today is to get rid of organic fuel
strong dependence and to use more intensively carbon sources
of energy. It is to be done urgently in connection with the
global warming on the Earth.
