Mine tailing particles are angular resulting in a high friction angle of dry tailings Given this environmental burden reasonable disposal of mine tailings examples are shown in Fig 3 is imperative The recent investigations focused mainly on recycling main tailings as a cemented paste backfill Zhao et al 2020
Recovering water from a tailing stream and using it again upstream in the plant reduces the amount of fresh water a mine needs The cost of water is frequently one of the primary drivers for implementing a thickened or paste tailings disposal system Stacking Surface stacking is the disposal of tailings on the surface of the ground

Mining is an important industry accounting for % of global GDP However global development promotes accelerated demand resulting in the accumulation of hazardous waste in land sea and air environments It reached 7 billion tonnes of mine tailings generated yearly worldwide and 19 billion solid tailings will be accumulated by 2025 Adding to this the
Submarine tailing disposal STD in fjords from land based mines is common practice in Norway and takes place in other regions worldwide We synthesize the results of a multidisciplinary programme on environmental impacts of STDs in Norwegian fjords providing new knowledge that can be applied to assess and mitigate impact of tailing disposal globally
The mining industry is a fundamental industry involved in the development of modern society but is also the world s largest waste producer
Improper disposal of the tailings poses a threat to the environment including Acid Mine Drainage AMD Dold 2014;Benarchid et al 2019 the collapse of a storage facility Macklin et al 2003
This document provides a general overview of Tailings Disposal Systems in these mining operations in Papua New Guinea It examines the challenges faced and the best practices employed to mitigate
Deep sea tailings disposal DSTD and its shallow water counterpart submarine tailings disposal STD are practiced in many areas of the world whereby mining industries discharge processed mud
Increasing population levels growing economies rapid urbanization and changes in consumption patterns have increased the demand for raw materials such as base and precious metals leading to growing concerns regarding their availability and the global efficiency of the mine supply chain Mine tailings consisting of process effluents that are generated in a
The mining industry is a fundamental industry involved in the development of modern society but is also the world s largest waste producer
Surface disposition of mine tailings in paste form is a new disposal technique and to achieve a desired depositional geometry it is necessary to characterize the paste s flow properties
Mining of Cu took place in Kvalsund in the Arctic part of Norway in the 1970s and mine tailings were discharged to the inner part of the fjord Repparfjorden Metal speciation analysis was used to assess the historical dispersion of metals as well as their potential bioavailability from the area of the mine tailing disposal It was revealed that the dispersion of
Adding to this the legacy of environmental damage from abandoned mines is worrying; there are around 10 000 abandoned mines in Canada 50 000 in Australia and 6000 in South Africa as well as
