Mar 15, 2016· The management of mine waste dumps has historically been assigned mainly to the on-site mining operations. In recent years, focus has turned to a more scientific approach to waste rock dump management and the auditing of these manmade structures.
A further layer of rock is then added and the process continues. An example is end dumping of waste rock with subsequent tailings deposition down the rill face prior to further end dumping. Injection of tailings into waste rock dumps via drill holes is another method of co-disposal of tailings.

1.1 WASTE ROCK MANAGEMENT PLAN OBJECTIVES The primary objective of this WRMP is to provide the geochemical testing and characterization program that will be implemented to guide the use, storage, and management of waste rock for the Project. Specifically, this first WRMP iteration discusses:
Waste rock is also a mine residue that typically consists of overburden and material displaced to access the ore body. Waste rock may even contain very low grades of ore but at levels which cannot be processed profitably. Waste rock management basically involves its removal and storage, which may be temporary or long-term.
Mine Waste Management. Waste management techniques employed by mining companies are routinely under intense scrutiny from local governments and the general public. Improper disposal methods and the resulting environmental damages have plagued the history of the mining industry.
Management of tailings and waste-rock in mining i EXECUTIVE SUMMARY Scope of this work This work covers activities related to tailings and waste-rock management of ores that have the potential for a significant environmental impact. In particular the work sought out activities that can be considered as examples of “good practice”.
Waste Rock Management Mine site closure and rehabilitation to the point of relinquishment is becoming increasingly more difficult, primarily due to water quality issues that require active ongoing management. The principal source of these water quality issues is contaminant generation and release from waste rock piles (WRP). Increasing numbers of mine sites are progressing to ...
environmental mine waste management technology. As a result of the literature search and scope refinement, fifteen environmental mine waste management strategies were identified for further investigation. In order to create an organized and efficient presentation, the fifteen strategies were divided into three generalized categories:

Research at the Porgera Gold Mine is focusing on developing a method of combining tailings products with coarse waste rock and waste muds to create a product that can be stored on the surface in generic-looking waste dumps or stockpiles. This would allow the current use of rivering disposal to cease. Considerable work remains to be done.
There are often different types of waste rock within a mine, some might be more harmful than others. One effective way of working with waste rock management is separation of different types of waste rock. When water and air starts to break down the waste rock, called weathering, the elements can be released to the environment.
Different guidelines on waste management, including post-mine closure, have also been developed at the international level. The term “waste” refers to material derived from primary production, which has no economic value at the time of production. This waste includes 6: – rock waste, which is aggregate with a high content of metals.
Waste rock Mining operations generate two types of waste rock - overburden10 and mine development rock. Overburden results from the development of surface mines, while mine development rock is a by-product of mineral extraction in underground mines. The quantity and composition of waste rock ... Mine wastes management ...
Ok Tedi environmental disaster ... it is a consequence of the discharge of about two billion tons of untreated mining waste into the Ok Tedi from the Ok Tedi Mine, ... This allowed all ore processing residues, waste rock and overburden to be discharged into the Ok Tedi River.
Waste Rock Dump Management and Stability Evaluation D Olivier SRK The management of mine waste dumps has historically been assigned mainly to the on-site mining operations. In recent years, focus has turned to a more scientific approach to waste rock dump management and the auditing of these manmade structures.
Waste Management & Infrastructure Conference – IIR Conferences, Melbourne, Sept. 2007 Dr G M Mudd Sustainability and Mine Waste Management – A Snapshot of Mining Waste Issues 3 A critical issue for tailings and waste rock is the potentially increasing scale of environmental liabilities associated with them.
Our associates manage mine waste with an interdisciplinary approach involving: mining engineering, civil engineering, water management, environmental engineering, and geotechnical engineering. Our associates can design not only routine waste rock facilities, but also can carry out complicated tailings compaction and consolidation studies, and dynamic (earthquake) stability analyses.

Waste Rock Definition The primary and most prevalent waste generated by many mining operations is waste rock, or overburden. Waste rock, which consists of rock and target minerals in concentrations too low for economic recovery, is removed along with the ore.
How We Recycle The Big Stuff. Rock and soil need to be moved to gain access to the coal, metal ores or other materials of interest. In some situations, it may be possible to sell rock and soil for a range of purposes as it is usually set aside for rehabilitation of the mine site after mining ceases.
