  • Mastering dry tailings management in challenging conditions

    Designed cake moisture was 16% but the system actually achieved moisture of 13-14% during the performance guarantee and has managed levels as low as 10-13%. In addition to its small footprint, key benefits of the system include: Recirculation of >86% of the process water present in tailings.

    The tailings slurry generated during beneficiation contains about 40-45% solids and has traditionally been managed in a conventional wet tailings dam. But, with this reaching its capacity and space on site limited, HZL was looking for an efficient and reliable dewatering concept to allow their Zawar site to continue operating and support the company’s planned expansions. This presented a

  • Dry Stack Tailings Design Considerations

    The design of a dry stack tailings facility is a balance between materials handling and construc-tion with the geotechnical properties of the tailings. From a materials handling standpoint, the facility needs to be designed to support the method of transport and deposition of the tailings to the facility (either conveyor or truck haulage). Therefore, the overall layout needs to include any

  • Economic and Socio-Environmental Benefits of Dry

    Generally, dry tailings from mining projects are considered as a source of construction material unless an evaluation shows it to be a source of risk on its own, or it is likely to be generated at high volumes that it exceeds the quantity needed for the construction purposes. Coarse dry tailings can be returned directly to the mined pit whilst in the case of fine dry tailings, they need to be agglomerated and backfilled into a

    01.10.2016· Vallourec's beneficiation plant produces concentrated iron ore lumps and fines in Pau Branco mine . Tailings are composed of both fines (>45 μm) and ultra-fines (<45 μm). Ultra-fines are generated from the de-sliming cycloning of the magnetic concentration process, and fines are the rejects of this process. Both fines and ultra-fines are disposed in a tailings dam inside the mine operation

  • Design Considerations for a Tailings Disposal System E

    The vendor would design and install it. Because the underflow from a conventional thickener, a tailings slurry, flowed according to Newtonian principles, each of the other aspects of the system could all be designed independently and they would work well. The principles behind high rate thickeners are based on unit area and the slurry it produces will eventually segregate into solid and liquid
