Abstract: Soil covers over mine waste rock dump tops in dry climates are intended to limit the ingress of oxygen and/or to limit the net percolation of rainfall infiltration into the underling potentially reactive waste rock excavated, in particular, on open pit mining. The climate in which the mine is located plays a key role. The aim of limiting the ingress of oxygen into the dump is to ...

Canada has developed a standard that recognizes four main classes of radioactive waste: Uranium mine and mill tailings. The main types of waste made by mining uranium ore are tailings and waste rock. Tailings are made from grinding uranium ore and has the consistency of fine sand when dried. The rocks removed to gain access to the ore is waste ...

The study included open pit optimisation and pit design, mining equipment selection, waste dump location analysis, operating and capital cost estimation, metallurgical parameters review, process and plant layout design based on sulphide flotation process, water supply, power supply, access roads, transport alternatives and economic evaluation.

Site description: There are twenty-three tailing dumps and thirteen waste rock dumps scattered throughout Mailuu-Suu, home to a former Soviet uranium plant. From 1946-1968 the plant produced and processed more than 10,000 metric tons of uranium ore, products which were eventually used to produce the Soviet Union's first atomic bomb.

2.1 Types of Waste Almost all wastes produced at a mining and milling operation can be divided into two classes. Mine waste is that product which is mined but which is not processed before being placed on a waste dump. Tailings is that product which,after mining and processing to remove the economic products, is discarded.Processing may range

The maze of open pits, waste piles, processing plants, at Krasnokamensk is the last major uranium mine still operating in Russia. These immense facilities sprawling across the steppe are the most extensive uranium operations in Asia and among the handful of the largest uranium mining and milling sites in the world.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): In many cases the placement of engineered cover systems on uranium mining waste dumps and tailings is required to avoid, or at least to reduce, pollution of water resources. In this paper, the failure mechanisms of cover systems containing a clay liner are set out and discussed, and essential design and construction ...

The effects of mine waste and tailings management on surface waters would depend on the amount and composition of the various waste materials, the methods used in processing the uranium ore, the ways in which the various waste materials are stored and disposed, and the steps taken to reduce the impacts on surface water quality.

the dump's overall grade which normally ranges between 0.2 to 0.9 g/t. Some mines even send the entire waste rock dump to the plant to make sure that all the gold gets recovered. This is typically done at Anglo Gold Ashanti's Vaal Reefs operations and Goldfield's Driefontein Mine. A number of mines have tried hand picking of gold ore,

environments: Rock cladding of tailings dams, this has been used to control wind and water (rainfall) erosion of the Doornkop tailings dam in the Westrand, Randfontein Estates gold mine [8]. Rock cladding can also be used to stabilize the slope of a mine dump. This seems to be the most practicable solution to these mine dumps.

drainage from a mine waste rock dump into surface water and groundwater systems. This study is being used to predict the efficacy of a soil covering for the waste rock dump to reduce leaching of uranium into the underlying and surrounding hydrologic systems.

Insitu mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground. The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to.
