Beyond scheduled repairs and replacements, the Udachny Division is making notable progress in environmental stewardship with the completion of new equipment installation for tailings thickening. Tailings, the waste material remaining after the extraction of valuable minerals, are a significant consideration in mining operations. The new tailings thickening and storage scheme, projected to launch in September, will enable the factory to reach its design capacity while significantly reducing its environmental footprint. By thickening tailings, ALROSA can recover and reuse a greater proportion of water, reduce the volume of material needing storage, and consequently minimize the physical footprint of tailings facilities. This innovative approach is expected to substantially reduce operating costs associated with tailings management and increase the overall efficiency of this critical process, aligning with global best practices for sustainable mining.
Unlocking New Value: The Quest for Type IIa Diamonds
Perhaps one of the most exciting developments under the PM program at Plant #12 is the implementation of a pilot scheme specifically designed to extract nitrogen-free diamonds, commonly known as Type IIa diamonds. These rare and highly prized diamonds are notoriously difficult to discover using conventional X-ray luminescent separators, which primarily detect diamonds containing nitrogen impurities. To overcome this challenge, ALROSA has mounted two advanced LS20-05-2N separators and modernized two radars-OD-50-03. This cutting-edge technology marks a significant leap forward in diamond recovery. The new system is specifically engineered to identify and extract Type IIa diamonds measuring 6 mm and larger, opening up a new avenue for increasing the output of large, high-value goods. The success of this pilot project will be crucial in assessing the feasibility of creating a permanent circuit, potentially unlocking substantial additional revenue streams and enhancing ALROSA’s portfolio of exceptional diamonds.
Mirny Division: Safeguarding Essential Infrastructure at Plant #3
At the Plant #3 of the Mirny Division, the 2020 PM program includes a vital infrastructure upgrade: the replacement of 1,000 meters of circulated water pipelines. Water management is an indispensable aspect of modern mining, particularly for continuous processing operations. Circulated water systems are critical for various stages of diamond beneficiation, and old or compromised pipelines can lead to leaks, inefficiency, and potential environmental risks. Replacing such a significant length of piping ensures the integrity of the water circulation system, prevents wastage, maintains optimal processing conditions, and contributes to the overall operational stability and environmental compliance of the plant. At the moment, this crucial project is 19 percent complete, demonstrating ALROSA’s ongoing commitment to foundational infrastructure maintenance.
Aikhal Division: Optimizing Small Diamond Recovery at Plant #14
