Environment Ministry Gave Positive Opinion to EIA Project of Gold Extraction Plant Re-equipment by "AT-Metals" LLC

RA Environment Ministry has issued a positive opinion to the project for a preliminary environmental impact assessment of the re-equipment project of Tashtun Gold Mining Plant submitted by At-Metals LLC.

"At-Metals" LLC received the soil management permit of Meghrasar gold mine for a period of 7.5 years in 2014. Shortly after the operation of the mine and plant in 2015, the works were stopped.

Under the project, the company had previously planned to extract gold using a thiocarbamide solution as a solvent. However, experiments have shown that the extraction of gold and silver from this ore is not effective in this way. It is currently planned to test the new SD-0103 solvent guaranteed by Chinese specialists for the extraction of gold and silver from ore.

It is planned to process 52,000 tons of ore annually. With the complete working system of the enterprise, the outflow of industrial wastewater into open pools will be excluded.

Under the project, the total emissions will amount to 46.51 t/year.

Drinking quality water from the drinking-economic network of Tashtun village will be used for both drinking-economic and technological needs.

Among the planned environmental measures are as follows:

1. Battery cyclones with an efficiency of up to 98% will be installed in the dry mill to trap the emissions.

2. Scrubbers are planned to absorb and neutralize nitric acid vapors during the separation of silver and other alloys from gold alloys.

The expert assessment requirements submitted to "At-Metals" LLC are as follows:

- Removal of industrial waste generated as a result of the work of the factory and carrying out the installation in accordance with the requirements set by the waste passport.

- During the operation of the plant it is necessary to observe the measures envisaged by the environmental monitoring plans.

- Observe the labor safety norms during the upgrade in accordance with the requirements of Chapter 23 of RA Labor Code.
