Environmental safety

The design solutions include three levels of environmental protection:

  • decontaminate, dehydrate and store semi-dry waste on a specifically dedicated site, protected by an impervious screen, to keep soil and water from drainage and runoff;
  • carry out water recycling (thus reducing the fresh water requirement of the company);
  • sorb gold onto activated carbon without the use of sulphuric acid in the technological process.

Mitigation measures:

on land resources:

  • carrying out the work strictly within the outlines of the project sites;
  • carrying out planning work, clearing debris and landscaping at the end of construction;
  • upon completion of operational works — reclamation of disturbed lands, including:
  • the technical phase (a set of activities aimed at preparing the land for its subsequent intended use);
  • the biological phase (a set of activities aimed at land reclamation after the technical stage works);
  • compliance with waste management regulations.

on the ambient air:

  • equipping organised emission sources with treatment facilities to purify process gases and aspiratory air. Efficiency is 85-95%;
  • using modern diesel technology with catalytic exhaust gas reduction systems that reduce nitrogen oxide emissions by up to 80%;
  • dust suppression of roads, hard mineral dumpsites;
  • closing the crushed ore stockpile, reducing dust emissions by 80-90%.

on flora and fauna:

  • transporting machinery only within designated on-site and off-site roads;
  • A preliminary survey of the area of Red Data Book plants and their replanting (if necessary) in agreement with the environmental authorities;
  • fencing of the industrial site in order to avoid accidental loss of wildlife.

on water resources:

  • introduction of technically based water and wastewater standards;
  • placement of project facilities outside the boundaries of watercourse protection zones;
  • drainage and treatment of polluted storm sewage from the infrastructure sites;
  • the use of an impervious screen for structures.

Environmental monitoring:

  • monitoring of both surface and drinking water for chemical, bacteriological and radiological indicators;
  • groundwater monitoring from observation wells near the Solid Mineral Waste site (SMW);
  • monitoring of effluent after the detoxification unit and residual water in the SMW for chemical parameters;
  • air quality monitoring at all facilities of the complex and nearby settlements;
  • monitoring of the condition and changes in flora, fauna and soil;
  • noise, vibration and radiation monitoring;
  • weather monitoring.
