A sustainable treatment for tailings dams. ViroMine Technology has been applied to treat all forms of mining waste, including AMD (which can have a pH as low as and be produced at disused mines for hundreds of years after mining operations have ceased), tailings dam water, and sulphidic mine tailings.
zinc from a lowgrade sphalerite concentrate produced from accumulated flotation tailings at Kumba''s Rosh Pin zinc mine in Namibia [11]. The main objective of this research was to investigate the zinc extraction using bioleaching process from the Kooshk lead−zinc tailing dam''s sample. Mixture of three mesophile bacteria, and mixture of four

Abstract. The total body concentrations of Pb, Cd, and fluoride were higher at the contaminated grassland site established on fluorspar tailings compared to an uncontaminated control site for all three species of small mammal, Apodemus sylvaticus, Microtus agrestis and Sorex was also higher in M. agrestis and S. araneus but in A. sylvaticus it significantly decreased and, overall ...
The Dairi Project, located 150 km South of Medan in the Dairi Regency in North Sumatra, Indonesia, invovled the design and construction of a 1 Mt/y zinclead concentrator and associated infrastructure.
However, two stumbling blocks complicate the ability of roasting lead–zinc tailings to satisfy the requirements of the SO 2 concentration. One drawback is that the sulfur content of lead–zinc tailings is 10–26%, significantly less than the sulfur content (34–48%) of pyrite that is the common raw material used in sulfuric acid production .

Modeling of dust dispersion from tailings dam were performed for two alternatives: (1) for the situation without damping (situation at the past when the whole of tailings dam surface represented a source of dust), and, (2) for the present situation when approximately two thirds of surface part of tailings dam is permanently damped with water.

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
