Ertis POX is Kazakhstan’s first large-scale and high-tech full-cycle pressure oxidation plant for refractory ore processing based on Solidcore assets in the country.
The plant unlocks country’s significant resource potential by developing new, refractory ore deposits for the processing of which there are currently insufficient production capabilities.
Pressure oxidation is one of the most sustainable and safe technologies in the hydrometallurgical industry.
Solidcore has extensive experience in this technology as it has already successfully developed two similar projects.
- No off-site water discharge.
- Water circulation with maximum water reuse.
- Minimal CO2 emissions with no SOx or AsOx emissions.
- Job opportunities for the local community
- Creation of approximately 500 permanent jobs. Over 1,000 jobs will be created during the construction phase.
- Increased tax payments to the local government.
- Increase of social investment
- Annual financial input into social care. Implementation of the most valuable social projects for the local community.
