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.

The new tailings filtering plant considers the processing of tailings from the Parcoy plant from its "overflow" process with a projected capacity of 2000 mtpd, receiving tailings with a 30% solid content by weight, until it is thickened and filtered, obtaining a "cake" with approximately 85% solids content by weight and a humidity of 15%.

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.

The Use of Acid Leaching to Recover Metals from Tailings: A …
Sulfuric acid concentrations of 2–8 M resulted in initial and final copper recoveries of 15% and 22%, respectively. Nitric acid, in concentrations from 0.01 to 14 M, yielded maximum copper extraction at 10.5 M, achieving 71% Cu recovery, with around 50% recovery within the 3–9 M HNO 3 range.

Our studies indicate that metals obtained from reprocessed tailings can be up to three times cheaper than ore. Some iron-ore mines have 50%-55% metals content in their tailings, which is amazing really. And there are copper operations with 0.5% of copper in their tailings which is higher than what's in the ground.

Considerations for tailings facility design and operation …
The tailings are first thickened to a given state, generally using conventional thickeners. The thickened tailings are then 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).

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 ...
