Importantly, mining sediment inputs composed of mill tailings from mineral processing can contaminate channel and floodplain deposits with metals such as lead (Pb) and zinc (Zn) for distances of several hundred kilometers downstream and to concentrations exceeding 5000 mg kg 1 (Ritcey, 1989, Horowitz, 1991, Miller and Orbock Miller, 2007).
Evaluation of tailings from processing plants is always an important issue. Lead Zinc ore tailings containing 3.12% Zn, 3.43% Pb, 0.71 g/t Au and 74 g/t Ag was subject to this study.

6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
minerals found in the tailings deposits were chalcopyrite, pyrite, pyrrhotite shaking table cleaning concentrator is a suitable process for gold separation from all the .. grained gold free gold is extracted by simple techniques such as gravity. 14 A review of gold particle size and recovery methods.
Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore.

Since Butte's founding during a gold boom, its principal industry has been mining. From the mid 1880s to the 1980s, Butte produced an estimated $22 billion in minerals mined. More than 8 percent of the nation's copper continues to be produced in Butte, joining other important minerals such as lead, zinc, and magnesium.

and soil are effective for selecting remediation strategies. A lead zinc mine and its tailings pond in Hunan Province (China) have an over 50 year history (Lei et al., 2015). However, there are few reports about the research on the mineralogical and chemical characteristics of tailing and soil of this pond.
Site 4 and site 8 had high V, Cr and Cu concentrations and high pollution level, because sites 4 and 8 were located on the margins of flat area where V mine tailings were stored. The high metal contents in site 11 was ascribed to leachate from V mine tailings on the top of hills.
The Mar Menor region had an important ancient Pb and Zn mine, where approximately 50 million tons of mine tailings have been dumped at the coastline from 1958 to 1991 and where subterranean groundwater discharged into the sea elevated concentrations of these metals (Cesar et al., 2009, Mar237;n Guirao et al., 2005, Trezzi et al., 2016).
The most valuable elements in a flotation tailings in Inner Mongolia were lead, zinc and silver, and the main lead and zinc minerals were oxide minerals such as cerussite, sardinianite, smithsonite and hemimorphite, and so on and the content of lead and zinc sulfide minerals such as galena, sphalerite were small. The flotation tailings was used
