Diversified mining and marketing company Glencore is auditing 140 slimes dams, 65 of them active and 75 of them closed. The company has been undertaking detailed assessments and audits of all material tailings storage facilities (TSFs) over the past three years, after accumulating a TSF significant asset footprint through mergers and acquisitions and organic growth.
KEYSTONE MINE TAILINGS GEOTECHNICAL INVESTIGATION WORK PLAN Figure 12 Site Layout SUMMARY OF PAST INVESTIGATIONS After mining operations ceased in 1975, a Geotechni cal and Hydrologic Investigation was performed by Woodward Clyde (now AECOM) in 1977 and remedial work was completed by AMAX Mining Company in 1979.
The Australian National Committee on Large Dams (ANCOLD) issued Guidelines on Tailings Dam Design, Construction and Operation in 1999 and subsequently produced an update in 2012. The document gives guidance on the planning, design, management, construction, operation and closure of a .
Mining Liners. Mining uses multiple liners for multiple functions: heap leach liners, solution pond liners, tailings dams. Check local regulations for lining materials requirements. Heap leach mining uses a chemical solution to dissolve metals in ore, which can then be collected by a liner and refined.

DAM AND POND LININGS. The damlining system comprises a geotextile fabric that is impregnated with a rubberised bitumen emulsion to create an impermeable membrane. The system is costeffective and has been used extensively in earth dams, oxidation ponds and canals.
Tailings Dam Construction Design of slime is likely to slide and cause the dam to break away. The procedure usually adopted in such cases is to separate the tailing into coarse sand and fines in a classifier, and to use the coarse product to build up the wall ; the remainder of the pulp is discharged into the interior of the dam.

These safety guidelines and good practices for tailings management facilities promote good practices that will help avoid accidents at such facilities and minimize the effects of any accidents that should still occur. By using these guidelines, Governments and industry are fostering the protection of the environment and human welfare in our region.
A conventional impoundment is a surface retaining structure designed to store both tailings and mine water, with the aim of reclaiming the water for use in the processing plant as required. There are principally two types of surface impoundments, a water retention type dam, and a raised embankment that has many configurations (Vick 1990).

and mining is a serious concern in Gauteng. It is possibly more pronounced here than in any of the other provinces. Mining is a major activity in Gauteng and as a result the province has a large number of slime dams, mine dumps, and landfills in areas earmarked for lowcost housing projects.
