Some villagers said tailings from the mines were clogging dams and rivers and affecting the availability of water for irrigation. In Marange diamond fields, these allegations were vindicated by a scientific research study done by the University of Zimbabwe and commissioned by the Zimbabwe Environmental Law Association which proved that there ...

The TAilings and IndustriaL waste ENGineering (TAILENG) Center is a research center dedicated to advancing the state of knowledge and practice in the design of tailings and industrial waste storage facilities. Recent catastrophic failures of tailings storage facilities, such as the Fundao dam failure, which killed 19 people and, historically, is considered the largest environmental disaster in ...

Tailings are finely ground rocks and other mineral waste as a result of mineral processing. Due to the way minerals are processed, tailings can contain concentrations of processing chemicals. This can make mine tailings an environmental concern, so proper transportation and disposal are crucial.

Around each dump, samples of leachate, tailings, downstream water, and upstream (control) water were collected. After collection, samples were stored in a cool place and analyses were performed at the Geology Department, University of Zimbabwe laboratory, using an Atomic Absorption Spectrophotometer (AAS) (model – VARIAN SPECTRAA 200HT).

waste called 'tailings,' the residue of an ore that remains after it has been milled and the desired metals have been extracted (e.g., with cyanide (gold) or sulfuric acid (copper)). If a mining project involves the extraction of a few hundred million metric tons of mineral ore, then

Project development follows a successful drilling programme on the tailings dump, which confirmed an indicated mineral resource amounting to 26 320 000 tonnes with grades of 0.58% lithium.

tailings dump. MATERIALS AND METHODS Description of the study area: The project was carried out on the active Shamva Mine slime dump, in Zimbabwe, which was established in 1982. The dump is terraced and rises at 0.121 m/year at a slope of 26 %. Each year four terraces are built and vegetated. The total area revegetated by 2004 was 7.15 ha.

Tailings from the West Rand and Free State regions, - however, would require both uranium and sulphide removal. Since the typical flowsheets currently used for dump retreatment do not necessarily result in responsible final processed tailings material with low AMD potential or low radioactivity, such a process advisor may reduce

12%A combination of factors are considered important in causing the failure and subsequent development of a flowslide of a gold mine waste dump (or tailings dam) at Arcturus, near Harare, Zimbabwe. These factors comprise poor basal drainage, steep perimeter walls, saturation of the walls and basal sediments through continued spigoting of slurry during a period of heavy rainfall, and …

Specific study sites were tailings dump tops of two mine tailings, 20 and 40 years after last deposition. The tailings were deposited against hills characterizing the area and are surrounded by other mine tailings ().The dump tops were rehabilitated by planting two native leguminous tree species, Senegalia polyacantha,and Vachellia karoo in 2001. . The plants were planted at a 10 m × 10 m ...

Mining took place between 1966 and 2001. The main sulphides were chalcopyrite, pyrrhotite, pentlandite and pyrite. Waste from the mine's plant has been disposed of via a tailings dam, the focus of this study.Surface water samples were collected at 12 sites around the slimes dam and groundwater samples were collected from six boreholes.

Lintmar's Zimbabwe Lithium Company (ZLC), in which Canadian-listed miner Chimata Gold Corp has a 19% shareholding, has been in a joint venture with ZMDC to extract lithium from the tailings dump at Kamativi's abandoned tin mine. However, a dispute with China's Pingchang has long delayed development.

(Ajusa, 2003). According to Ermite (2004), mine effluent is a term used to describe waste water from mines that includes waste rock or tailings depositories, slimes dams, and/or draining into an adjoining body of water, including streams, lakes aquifers, wetlands, and oceans. The Ministry of Mines (1990) assets that effluent is

The research results on floatability of old gold-bearing tailings are presented. The complex material composition and process features of processing waste are governed by difference in treatment of various ore types (sulfide, oxidized and mixed) at processing plant, as well as with supergene processes in the tailings pond. Feasibility of re-flotation of tailings is discussed. It is found …

Tailings are waste, the material left behind after the metal has been extracted. In that waste are also remnants of gold and in the case of Zimbabwe where gold mining has been undertaken for centuries the tailings when treated with the latest extraction methods provide a commercially viable yield of 99.9% gold.

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.
