Gold ore and the solution for Gold ore Processing
Within all the metal, only gold poured in human
economic life and it has such a significant influence to
the human society. In the thousands of years of
human civilization history, through the years, the up
and downs, honor or disgrace, lift uncertain, the social
status of gold have never changed and it still the
wealth that puersued by all the people. We will give
you the key to concentrate the gold from the mineral
ore.
Gold ore means the mineral ore which is with
sufficient Au elements and it is with ndustrial
exploitation value. Here is the several common gold ore
for your reference as below:
2. The processing technology for the gold ore:
Coarse gold ore:
a. Gravity Separation+flotation
b. Gravity Separation+ CIL processing technology
Fine Gold ore or the gold ore with high flotability ( like
Sulfide gold and silver, the gold is associated with qurtz)
a. Flotation processing
b. Flotation+ CIL processing
c. CIL processing
Gold is in fine-grained or the microgranular is
decentralized in quartz vein ore orthe gold ore is with
very high oxidation degree, not including Cu, As, Sb, Bi
and carbon.
a. Cyanidation
b. Or Cyanidation leaching processing ( CIL processing or
dump leaching)
3. How to setup the gold ore processing plant?
Frist, doing the geological prospecting to know the
deposit, position and the trend of your mine and make
sure it is with the the feasibility of developing or not.
Second, doing the dressing test is for choosing the
suitable and economical mineral processing technology
and recovering the Au element inside the raw ore
after detailed experimental study. The research report
will be as the basis of the project feasibility study.
a. Spectral analysis & elements chemical analysis to fix
the chemical composition of Au ore. And the grade of
the Au elements like in the below table is 3.14 g per
ton.
b. Glod ore phase analysis to fix the type of your gold
ore and the gangue name.
c. The texture and structure and mineral composition
of the ore; To know the valuable mineral of your gold
ore like the tetalite, manganocalcite, rhodochrosite,
capillitite and the gangue which is associated with the
manganese ore like,clay, pyrite, quartz, calcite etc.
d. The major metal mineral's embedded features; The
Major element mineral's dissociation. To fix the suitable
particle size to separate the valuable mineral and
gangue.
e. Condition test; Base on the research, we will doing
the condition test include grinding solution; grinding
fineness CIL concentration solution; collector type and
dosage; depressant type and dosage; activator type and
dosage; modifier type and dosage; PH value; processing
time; pulp density, etc for fixing the technological
parameter of beneficiation flowsheet and the result is
as below:
f. Completely open closed-circuit test: Base on the
above test, choose the beneficiation technology process
and the process parameters. The test index should be
with repeatability, stability and facticity.
g. Product check: Make multi-element analysis for the
concentrate and tailing; Make sedimentation
performance test for the concentrate and tailing.
h. Designing the beneficiation flow-sheet:Base on the
above test, designing the most suitable beneficiation
flow-sheet,technological parameter and reagent system.
i. Issuing Report Issuing report base on the above tests.
Third, choosing the suitable equipments base on the
above test result.
Forth, build the foundation and doing the installation
with our engineer. After receiving the deposit, we will
send the technical drawing to you and send our
engineer to supervise the foundation building and guide
your staff to do the installation, then have a
commissioning running. Meanwhile, they can train your
staff at your site also.
4. Here is one project of Gold ore Processing plant as below
a. In the crushing section, crush the raw gold ore into
size 0-10mm. It is prepared for the beneficiation
process.
b. In the grinding system use the ball mill to grinded
the crushed gold ore from 0-10mm to 75 microns with
passing rate like 80%. ( This particle size should be fixed
by the dressing test.)
c. Then use the hydrocyclone to classify the gold ore
with the suitable size and then send to the thickner
to dewater. The over size gold ore will be returned to
the ball mill to grind it again.
d. The gold slurry from the thickner will be sent to the
agitation tank to mix together with the cyanide and
slaked lime. Then the slurry will be sent to the CIL
system for cocentrating process. The active carbon will
collect the Au ion.
e. The carbon loaded with gold will be collect and send
to the pickling tank to adjust the PH and remove the
heavy metals elements and the carbonate in the
pickling tank.
f. The carbon after the pickling elution will send to the
electrolyte tank to desorb the carbon and gold
elements. The liquid which is rich in Au will be sent to
the lectrowinning tank. The carbon will send to the
carbon storage tank.
g. The Au ion liquid will be collected by the cathodes
and then use the smelting oven to get the coarse gold.
( If the coarse gold contain Hg, it should be processed
by the evaporate mercury device to remove the hg.)
h. The carbon after the electrolyte process will be
stocked into the carbon storage tank, then use the
screen to do the dewatering. The dewatered carbon
will send to the rotary kiln to do the carbon
regeneration. The regenrated carbon will be classifyed
by the screen, the suitable carbon will be sent to the
CIL system for cyclic utilization, the fine carbon will
be dropped.
i. All the waste liquid with cyanide should doing the
cyanide destruction and the sewage treatment in the
waste pound. The water can be cyclic utilization and
the talings will be send to the tailings lake. ( You can
also choose to use the technology of pressure filtration
and dry heaping of tails.)
This design is just for your reference. The precise design
for your plant should be done base on the dressing test
of your raw mineral ore. Because this customer just
want to improve the grade and selling the mineral ore
directly.
