PY - 2020 DA - 2020/05/26 TI - Flow Enhancement of Mineral Pastes to Increase Water Recovery in Tailings: A Matlab-Based Imaging Processing Tool SP - 5607242 VL - 2020 AB - The rate of growth of mining copper industry in Chile requires higher consumption of water, which is a resource limited in quality and quantity and a major point of concern in present times. In addition, the efficient use of water is restricted due to high levels of evaporation (10 to 15 (l/m2)每天),特别是在北高方矿业(智利)。相反,尾矿的最终处置主要是池塘,通过蒸发和在某些情况下渗透到渗透。替代方案是糊剂增稠剂,其产生稳定的糊状物(70%固体),降低蒸发和渗透,从而减少水化妆。水是一种资源,随着行业的扩展,水恢复过程比效率简单升级更加需要。这项技术是在加拿大(80年代初期)开发的,它广泛用于澳大利亚(干旱区,天气条件与智利相似),尽管很少有工厂正在使用这种技术。在不久的将来的趋势是从开放的池塘移动到粘贴增稠剂。其中一个例子是Minera El Tesoro。这种情况需要在粘贴流量表征和流变改性器(流动性增强剂)中开发技术能力,以便使这种粘贴的最终处置。在这种情况下,引入了一种新技术,并讨论了流动改性剂的实验结果。本研究描述了水量如何影响尾矿和二氧化硅面粉浆料的流动行为和沉积几何形状。 The depositional angle determined from the flume tests, and the yield stresses is determined from slump test and a rheological model. Both techniques incorporate digital video and image analysis. The results indicate that the new technique can be incorporated in order to determine the proper solid content and modifiers to a given fluidity requirement. In addition, the experimental results showed that the pH controls strongly the fluid paste behavior.
