MINE REHABILITATION AND THE COMMUNITY: A CASE STUDY FROM CANADA Dr David Laurence Associate Professor School of Mining Engineering University of New South Wales Sydney, Australia ABSTRACT OF PRESENTATION: The writer recently undertook field research and attended the International Mining and Environment Conference in Sudbury, Ontario.
7 Figure 3: Composite photograph of the Quebec Lithium mine taken in 1959. (From Stone and Selway, 2009) The lithium market became volatile in the late 50's and because of this the mining and refining complex operated on a periodic basis. A decision to close was made in 1966.
Progressive rehabilitation is the process of rehabilitating waste rock dumps and tailings storage facilities shortly after they become available. KCGM has a programme of progressive rehabilitation of our significant waste rock dumps and tailings storage facilities which is scheduled to coincide with available rehabilitation materials and equipment.
Jul 03, 2013· Case Studies. Rehabilitation of the Barzava Uranium Mine Tailings ... Results are presented and discussed concerning the radiometric survey of the Barzava uranium mine tailings (Arad District, Romania), a 20,000 m 3 sterile dump, before and after rehabilitation.
DRAINTUBE provides technical and innovative solutions for mines rehabilitation, tailings drying or dams drainage. DRAINTUBE effectively drains liquids and gases even under extreme conditions. For many years, AFITEXTexel has developed and manufactured multilinear drainage geocomposites to decrease pore pressures in the soils.
The reestablishment of an ecosystem on a virtually sterile land base (mine tailings) is addressed as a problem facing mining industries (Case ). Despite the fact that the reseeding project was not primarily undertaken as a study of ecosystem rehabilitation, it was hoped that such a report would identify those
cases a combination of open pit and underground mining occurs, although usually sequentially in the mine lifecycle, rather than simultaneously. At underground mines the rock dumps, tailings dams, and loadout facilities are the main causes of dust emissions, whereas at .

Report also discusses tailings embankment and stability and briefly discusses water management in tailings impoundments. Includes a case study on a lined tailings impoundment. The report relies heavily on Steven 's book (see above). Watch out: Figures 811 are mixed up!] Order address: National Technical Information Service
Manitoba Orphaned/Abandoned Mine Site Rehabilitation Program Manitoba announced in September 2006 a new 70 million program to fully rehabilitate Manitoba's former mine sites; this includes the Manitoba component of the tailings work at Lynn Lake described above.
The concept of 'deposition for closure' using thickened tailings is explored, with a case currently in the early stages of implementation for a TSF at a gold mine .
The mine team also reclaimed two tailings deposits that were remnants of gold and arsenic operations from the early 1900s. The hectare tailings storage facility was drained, secured with an additional liner, and regraded.
Case Study 11: THE ISSUE: Mine closure is a complex process requiring careful planning from the beginning of a project's lifecycle. The planning horizon is measured in decades, and planners must deal with social, economic and environmental issues that will inevitably change over a mine's operating life.
