Zhang et al. [23] studied the process mineralogy of copper ores and found that copper minerals are mainly sulfide minerals that are easily floated, but most of them are embedded at around 0.3 mm, requiring a grinding fineness of 85–90 % −300 mesh to make the copper ore fully dissociated. The study of process mineralogy holds a significant ...

In arid climates these additional water savings can offset the costs of the filtration process. Major increases in cost and availability of water is leading to mine operators starting to examine dry tailing solutions more closely. Potential water recovery potentials for copper flotation tailings are shown in the below table.
Tailings samples were collected from a post-operative copper mine tailing site, which was active until 2006, located at latitude 24° 9′58.33″ S and longitude 69° 2′33.36″ W at an altitude of 3200 m.a.s.l. The tailing contains high concentrations of metals such as Cu, Fe, Zn, Mn and Pb.

delivered to the filter plant. There is a large variety of filters that may be used, including vacuum types (drum, disc, and belt) and pressure types (plate and frame, and belt press). Bedell (2006) provides a great deal of information regarding thickening and filtering of tailings. The filtered product is often referred to as 'filter cake'.

COPPER THICKENING AND FILTERING. The thickening and filtering is similar to other milling operations, however, as the porphyry copper installations are often in arid areas, the mill tailing is usually sent to a large thickener for water reclamation and solids go to the tailings dam. ... Flotation of Copper Ores. In most plants engaged in the ...

An alternative process to obtain a high degree of dewatering tailings that produces a high-density product is presented in this article. This technology involves the combination of tailings particle grain size classification by hydrocyclones (HC) and tailings dewatering by horizontal vibratory screens (HVS). It makes it possible to dewater tailings …
Filtration has also been adopted in operations where process flow sheet dictates its use. Davies (2011) noted that two most common reasons to select dry stacked filtered tailings have been to ...
In Chile, current estimates for the cost of desalinated water pumped to the mine are as high as $5 per cubic meter or higher. There are four main filtration options for dewatering …
The dewatering plant includes a drop-down zone for filter components conveying to a stockpile to loading onto a truck under upset conditions by the mine tailings filtering plant (See Figure 3).

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.
