Beyond routine scheduled repairs and replacements, the plant is nearing completion of installing state-of-the-art new equipment for tailings thickening.
Tailings, the waste material left over after the valuable diamonds have been extracted from the ore, present both operational and environmental challenges. The new tailings thickening equipment is designed to significantly reduce the water content within these waste materials. This process results in a denser, more compact material, which is crucial for the implementation of a modified tailings storage scheme. Once launched in September, this project will enable the factory to reach its design capacity with a dramatically improved storage methodology. The benefits of this new tailings thickening and storage scheme are multifaceted: it will substantially reduce operating costs by minimizing the volume of material requiring storage and transportation, decrease the environmental footprint of the storage facilities, and enhance the overall efficiency of water recycling within the plant, showcasing ALROSA’s commitment to responsible mining practices.
Moreover, under the vigilant eye of the PM program, Plant #12 has initiated a groundbreaking pilot scheme aimed at extracting nitrogen-free diamonds (Type II diamonds), which are notoriously difficult to discover using conventional X-ray luminescent separators due to their unique atomic structure. These diamonds, particularly Type IIa, are exceptionally rare and highly prized for their superior clarity and often larger size.
To facilitate this advanced extraction, ALROSA engineers meticulously mounted two specialized LS20-05-2N separators and modernized two radars-OD-50-03. This cutting-edge technological integration represents a significant leap forward in diamond processing. The new technology is specifically engineered to detect and extract Type IIa diamonds measuring 6 mm and larger. The successful implementation of this pilot project holds immense potential, promising to significantly increase the output of large, high-value goods, thereby adding substantial value to ALROSA’s product portfolio. The results of this pilot initiative will be rigorously assessed to determine the feasibility and strategic advantages of establishing a permanent circuit for Type II diamond extraction, potentially unlocking a new stream of premium quality diamonds.
Mirny Division: Critical Infrastructure Upgrade at Plant #3
At the Mirny Division’s Plant #3, the 2020 PM program includes a vital infrastructure upgrade focusing on the plant’s circulatory water system. This involves the extensive replacement of 1,000 meters of circulated water pipelines. The integrity of these pipelines is paramount for maintaining the continuous and efficient operation of the plant’s processing circuits, as they transport water essential for various stages of beneficiation, cooling, and washing.
Replacing such a significant length of piping is a preventative measure against potential leaks, pressure drops, and system failures that could lead to costly downtime and reduced operational efficiency. Ensuring the robust health of the water circulation system directly contributes to sustained productivity and minimizes environmental risks associated with potential water loss. As of the latest update, this crucial project is 19 percent complete, with ALROSA project teams working diligently to finalize the replacement, thereby reinforcing the foundational infrastructure of Plant #3 for years to come.
Aikhal Division: Innovating for Small Diamond Recovery at Plant #14
