copper tailing filtering plant


  • Experimental study on the utilization of copper tailing as …

    The gradation curve of copper tailing modified sand was expected to be similar to Fuller curve as much as possible and be classified into zone II. With the increase of copper tailing content, the number of particles ranging from 0.075 mm to 0.6 mm increased, which decreased the convex level and slope of mixed sand gradation curves.

  • Mitigating tailings risk with filtering and co-disposal

    The challenges of tailings filtering. Although dewatering is often referred to as dry stacking, the name can be misleading because the filtered tailings can still retain 10%-20% water content. While the residual water itself isn't a problem, the inability to regulate how much water each filtered tailing stores is.

  • Practical thoughts regarding filtered tailings

    The application of filtered tailings technology appears poised to make a dramatic leap forward, moving from use at a limited number of relatively low-production-rate operations (6,000 tonnes per day (tpd) or less) to greater adoption and use at relatively high-production-rate facilities (exceeding 50,000 tpd).

  • What are Tailings

    Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt ...
