Saving Fresh Water and Costs in Tailings Drainage in the Mining Industry During the processing of ores and minerals finegrained residues in the form of sludges called tailings occur in mining Tailings are still frequently stored in large sedimentation basins or sludge ponds

Dry tailings – less for you to worry about Tailings dams have been a part of mining operations for decades However every year dams will leak causing environmental damage to the surrounding areas Furthermore dams require upkeep and maintenance leaving mine owners with high continuous costs for management This incentivises moving

The basic submarine tailings disposal design comprises a tailings line to a deaerationmixing chamber with a seawater intake line and discharge to location and depth allowing gravity flow of a coherent density to the final sedimentation area

The tailings will be pumped by centrifugal pumps to a different location which is approximately 4 km away from the thickening plant see Figure 3 At the point of discharge tailings will be injected with polymer A multiple spigot discharge scheme will be implemented to control tailings flow velocity discharge energy and beach slope

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore Tailings are distinct from overburden which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed The extraction of minerals from ore can be done two ways placer mining which uses water and gravity to

Alfa Laval’s solidbowl decanter centrifuges are the perfect choice for a wide range of solidliquid separation duties in mining and mineral applications They can replace or complement existing solutions and help boost capacity reduce tailings volumes save space and increase the recovery of water chemicals and minerals

Dry stacking of tailings at La Coipa has been possible due to advancements in large capacity horizontal belt vacuum filters The tailings 18000td are dewatered to contain lt20 water content depending on the specific gravity allowing them to be either trucked or transported by conveyor to the disposal site

As part of a significant investment to improve its processing facilities and enable the recovery of 40 of the gold that currently sits in its tailings as waste a mining operation in Mexico called in a leading transfer point and chute systems equipment manufacturer to conduct a thorough assessment on the functionality of existing chutes in the plant

Certain achievements have been made in mineral processing screening and dewatering Especially in response to the call of national energy saving and emission reduction great achievements have been made in various metal and nonmetal tailings dry discharge and zero emission research projects

In a waterpositive environment subject to highly seasonal rainfall Veolia enables a gold mine in Ghana to manage its tailings overflow and meet the local discharge requirements By upgrading the wastewater treatment plant reviewing operations practices and training a dedicated local team Veolia allowed AngloGold Ashanti to maintain and improve its operations

The dewatering technology produces a cake with up to 70 dry solids by mass which can then be used for codisposal with coarse rejects Tackling tailings safely and sustainably Alfa Laval decanter centrifuges are a proven efficient solution for largescale dewatering of tailings and removing the finest particles that conventional solids control equipment is unable to deal with

Our paste tailings solution uses a thickener resulting in 65 to 70 solids in underflow to recover water in tailings prior to disposal With this option the tailings have been significantly dewatered to a point where they do not have a critical flow velocity when pumped do not segregate as they deposit and

Tailings dry discharge process flowsheet In Current years Tailings dry discharge is a gradual emerging new tailings treatment process It means the tailing pulp from dressing plant through multi concentration then use dewatering vibrating screen to treat and get low moisture easy sediment solidify and good for

Dewatering is an important part of traditional wet tailings storage As tailings are added to the storage facility water is usually returned to the mill for reuse This also reduces the hydraulic pressure on the dam walls Goldcorp has become a leader in filtered tailings also known as “dry stack”

Thickeners are recognized as one of the more costeffective technologies for recovering water from tailings streams Significant energy savings can be achieved by maximizing the recovery of water close to the mill In addition a higher density of tailings deposited in the dam tends to reduce the footprint and produce a more stable tailings deposit
