Self-sustainable process of mining

MINING SECTOR

Traditional or small-scale mining and mining by large multinational corporations on a large scale has used methods such as amalgamation. In this one, the main input is the mercury, that today is part of the illegal mining.

The processes of flotation, cyanidation and activated carbon allow to reach LESS THAN 90%, deteriorate the grade gold and take a long time..

With the implementation of Nanolixiviation, a method of self-sustaining Gold Extraction, developed by Nanotecol, mining could become a highly profitable, clean, sustainable, environmentally friendly and nationally and internationally prestigious mining.

Nanotecol has been able to develop, through nanotechnology and biotechnology, a mining extraction process that reduces costs, increases production efficiency and improves the quality of gold, all without generating pollutants to the environment.


Increased gold extraction

Nanotecol in its pilot plant, with a nanocatalyst, adequately tests the material of the mine, where it is identified:
• The methodology to build the plant to ensure the highest gold extraction.

Highly efficient

In the filtration, deaeration and precipitation, cementation and purification, adaptations and changes are made, to optimize the extraction of the gold through the nanolixiviation.

No contaminated landfills

In this process:
• Only cyanide is used, which is filtered and mediated by leguminous plants.
• Sludge is free from contaminants and can be used in: pavements, bricks, silicate industries, etc.
• Gold is obtained without deteriorating its law.
• It saves up to 40% of chemical inputs by eliminating peroxide and oxidants.
• The use of cyanide is minimized.
• Cyanidation process is accelerated. In a total of 4 hours.

.

Clean and self-sustaining

Nanotecol has developed a cyanivorous plant:
• Able to use cyanide as fertilizer and remove it from the environment.
• Serves as fodder for livestock.
• It is the largest CO2 capture.

This plant, uses cyanide as fertilizer and removes it from the process, serves as fodder for cattle, is the largest capture of CO2.




Nanolixiviation
Self-sustaining gold mining


The nanolixivation is performed with a nanocatalyst, which is a nanotechnology device containing nanoparticles. In this process the dissolution of the gold is accelerated between 4 to 6 hours and the use of reagents is eliminated.

Comparison of the traditional process and the Nanotecol process


Tradicional process

Nanotecol mining

Cyanidation time: 20 to 48 hours Cyanidation time: 4 hours
Total extraction time: 4 days Total extraction time: 1,5 days
With cyanidation less than 80% of the gold is obtained in the material With Nanolixiviation 100% recovery of cyanurable gold.
Consumption of reagents: Cyanide, cement, peroxides, others Consumption of reagents: cyanide in less quantity
Generates dump of heavy metals in the rivers.
Large ponds are used to store cyanide solution, often next to a river

No contaminated water to store.
The only dumping cyanide is consumed and eliminated by the cyanivorous leguminous plants.

Peroxides tend to damage the gold grade The gold grade is not modified, because no peroxides are used
Tons of contaminated sludge and high cost of disposal Clean sludge suitable for road construction, brick making and the silicate industry






Extraction of gold by Nanolixivation.

100% recovery of cyanurable gold.Elimination of reagents. It saves up to 40% of other chemical inputs. The use of mercury is eliminated.

.

1. MILLING

The need for milling of the mine
is identified to establish the ideal
extraction process for
the 3 gold sizes (macroscopic,
microscopic, nanometric).

2. NANOLIXIVIATION

The Nanocatalyst is introduced, which
accelerates the process of dissolving
gold between 4 to 6 hours and
eliminates the use of reagents.
It uses air to produce traces
of ozone and ammonia.

3. FILTERED

The rotary filter is introduced to
separate the rich solution from the
inert sludge and recover the maximum
dissolved gold, avoiding the tailings.

4. DESAIREATION

The oxygen is removed from the
solution with gold and cyanide.
The remaining solution
passes through a tank.

5. PRECIPITATION

Precipitation takes place in 3 hours.
It is possible to carry out the
process by filter press or bags.

6. CEMENTATION

At this stage the great novelty
is the elimination of
polluting gases.

7. PURIFICATION

A prewash with acid is used before
entering the muffle for 2 hours,
where the separation of noble
metals occurs.

8. CYANIDE CONSUMER
PLANTS

In the cyanide remediation phase,
impoverished cyanide solution is
filtered throughout the process and
reserved for use in a drip irrigation
system in a cyanivorous leguminous
planting area that uses cyanide
as fertilizer.

REMEDIATION OF CYANIDE

Bridge between the mining operation and the environmental regulation system.

In order to avoid the use of contaminated sludge ponds, a cyanivorous legume crop plant is used in the process to treat cyanide. In the cyanide remediation phase, impoverished cyanide solution is filtered throughout the process and reserved for use in a drip irrigation system in a cyanivorous leguminous planting area that uses cyanide as fertilizer.
s The cyanivorous plants plant adapts very well to livestock. It is forage and serves to feed animals. These plants capture CO2 , generate carbon sequestration conditions, to reduce CO2 emissions.
