“…The Chungar Mine is located in the Department of Pasco, Province of Cerro de Pasco and District of Huayllay, Peru. It is a polymetallic deposit that contains copper, silver, zinc, and lead, an underground working mine, and whose workings are at the 4100 masl [44,72].…”

“…The hydrocyclone overflow is diverted to transfer tank "A" where it is mixed with water from the underground mine. The overflow mixture plus underground mine water (slurry) is sent to the deep cone thickener 17 m in diameter × 21 m in height (Figure 55) through 01 pumping line (12″ diameter HDPE pipe) composed of 03 pumps in series of 200 HP power each, in addition, it has a standby line [44,72]. The discharge of the tailings in paste from the thickener is carried out by means of 02 centrifugal pumps of 150 HP of power, the other a duplex peristaltic pump of 50 HP of power, also, the discharge is carried out by gravity (depending on the characteristics of the tailings in paste), a through the conduction and transport lines with a 10″ diameter HDPE pipe, disposing of it in No.…”

The solids concentration range of paste tailings for surface disposal is from 71 to 74% solids by weight (Cw), with peaks of 76% solids (Figure 57) [44,72]. The DCT operating discharge flow range is 5500 mtpd, considering the overflow of the hydrocyclone battery plus underground mine water as feed.…”

The “Thickened Tailings Disposal” (TTD) technology produces a high density mine waste that allows for the storage of this material without the need to manage large slurry tailings storage facilities (TSFs) and large dams. TTD has been applied considering site specific conditions of Chile and Peru, such as extreme climatic conditions, seismic risks, water scarcity, community demands, and environmental constraints. This review highlights the contribution of several experiences in Chile and Peru, which have chosen TTD technology for reduction of negative environmental impacts, mainly focusing on the following issues: (i) increase of tailings water recovery, (ii) reduction of TSFs footprint (impacted areas), (iii) decrease the risk of physical instability, avoiding the construction of high dams, and (iv) decrease of TSFs seepages. Finally, the article describes the advantages (benefits) and disadvantages (aspects to improve) of TTD, where nowadays a high degree of dewatering of tailings is seen as a safe option, considering the occurrence of some TSF dam failures recently worldwide, which has resulted in severe environmental pollution. A better environmental perception about TTD of authorities and communities, considering that this technology allows to satisfy the needs of stable and safe TSFs, make the TTD be more acceptable, popular and one of the best available technologies (BATs) for operations with mine tailings.

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 to a high grade of performance. This alternative technology (HC-HVS) involves the recovery of water from the coarse fraction of tailings (sands) through two hydrocycloning stages, followed by a dewatering stage of cycloned tailings sands on horizontal vibratory screens, to reduce moisture content and turn it into a “cake “. The resulting coarse fraction tailings are easily transported to a dry stack tailings storage facility (TSF). The fine fraction of tailings (slimes) can be dewatered on thickener equipment to recover part of the process water. Finally, this article describes the main benefits of this alternative dewatered tailings technology with an emphasis on (i) dewatering technology evolution over the last 17 years; (ii) process stages features; (iii) pilot test results; (iv) tailings properties analysis (such as particle grain size distribution, fines content) and (v) lessons learned about the experience gained in the operation of Mantos Blancos case study with dry stack tailings storage facility.
