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),特别是在北方高地的采矿点(智利)。相反,尾矿的最终处置主要是对池塘,它通过蒸发和在某些情况下渗滤失去水分。一种替代是浆料的增稠剂,这产生稳定的糊状物(70%固体),减少蒸发和渗滤,并因此减少水的组成。水是有更多需求的行业正在扩大,使水回收过程的必需品超过了效率的简单升级的资源。该技术是在加拿大(80年代初)开发,并已广泛在澳大利亚(具有类似气候条件智利干旱地区)使用,虽然一些植物都采用这种技术。在不久的将来的趋势是从露天池塘移动到粘贴的增稠剂。其中一个这样的例子是萨尔瓦多矿业泰索罗。此方案要求,以使可能的本贴的最终处置发展中国家在这两个贴流动特性和流变改性剂(流动性增强)技术能力。在这方面,一种新的技术被引入和流动性改进剂的实验结果进行讨论。这项研究描述含水量如何影响流动行为和尾矿的沉积几何形状与石英粉糊。 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.
