Brief Introduction to Changchun Gold Research Institute
Changchun Gold Research Institute
was founded in 1958, which is the only national
level scientific research organization specialized
in the research of basic theory on gold industry
and engineering technology development. At the
same time, the Technology Center of China National
Gold Group Corporation, National Monitoring Inspection
Center for Gold, Silver and Their Products, and
China Gold Environment Monitoring Center are affiliated
with Changchun Gold Research Institute; “Gold
Magazine” is also set up in this institute.
With the development of Chinese
gold industry, our institute has already formed
an integrated research and development system
with complete scientific research organizations
and advanced technical facilities. We have a high
qualification, high standard technical team strong
in scientific research, product development, technique
design, project management and production management.
During the course of all the important
technical upgrades of the gold industry, our institute
provided various technical supports, such as the
application of mechanical resuing method for narrow
vein mining; introduction and application of whole-slurry
cyanidation and CIP process; the development of
the technology of gold extraction from sulphate
calcine; research on gold extraction by the process
of bio-oxidation and cyanidation; technology of
gold recovery from wastewater in tailings; development
of integrated ulilization of refractory gold resources
and old tailings, and so on.
Many years of research and development
have formed outstanding technical superiorities
of our institute:
In areas of mineral processing
and metallurgy, besides providing the mines with
regular technological minerology research, mineral
processing test, process of precious metals extraction,
gold refinery and purifying, we can also provide
comprehensive technical services and technical
consultation in design, industrial and technical
regulation, and commissioning for mineral processing
plant. Especially in the aspects of gold extraction
from refractory ores with highier arsenic content,
highier sulphur content , and containg carbon
and impurities, our institute possesses rich experiences
and advanced technical means.
In environment protection, we
have the patented technologies of peroxyll oxidization
method and two step precipitation process for
further treatment of waste water with high content
of cyanide and we also have rich experiences in
the pollution treatment of cyanide-containing
tailings pulp, arsenic-containing wastewater and
nitrogen oxides containing waste gas.
In mining, our institute has very
strong technical superiorities for the mining
of narrow and extremely narrow veins, as well
as high efficiency mining of thick orebodies,
the control of stope roof for broken mine as well
as maintenance of broken roof for inclined and
steeply inclined orebodies, backfilling system,
rock mass reinforcement technology, ventilation
and dust control and deep shaft cooling technology.
The bio-oxidation technology is
our newly developed proceesing technology, which
is at the advanced level of the world standard.
We have separated, cultivated and acclimatized
many kinds of mixed bacterium that are widely
used with high oxidation efficiency. Applying
this technology, our institute undertook the National
Demonstrating Project for high-tech industrialization
--- the design and construction of Liaoning Tianli
100 tons/day Biological Oxidation Plant, this
oxidation plant was tested, designed, and constructed
by our institute alone and we independently own
the intellectual property for it.
Enterprising and innovative is
our criteria; hard working and dedicating is our
everlasting faith; satisfactory and trust of customers
is our permanent commitment; quality first and
customer first is the guarantee to win credits.
By our high quality and efficient services, we
would like to sincerely welcome people from different
domains to work together with us and create the
bright future together.
