Mine Tailings, Tailings in Mining, Gold Tailings
Iron tailings: the iron tailings discharge from iron ore plant is in large amount, fine size and different types, and complex property, so Xinhai use the process of magnetic separation, flotation, acid leaching and flocculation to recover iron. Gold tailings: Xinhai usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings.

Chemolithoautotropic Diazotrophy Dominates the Nitrogen
Nutrient deficiency, especially bio-available nitrogen deficiency, often impedes the bioremediation efforts of mining generated tailings. Biological nitrogen fixation is a critical process necessary for the initial nitrogen buildup in tailings. Current knowledge regarding the diazotrophs that inhabit tailings is still in its infancy. Therefore, in this study, a comprehensive investigation

The Mining Process – Waihi Gold
9. Tailings disposal Waste rock from the open pit mine is used to build the embankment structures. The embankments retain the tailings slurry in a pond where solids settle and compact. Water is decanted off and used in the process plant or treated before it is discharged. See more detail on tailings disposal

Tailings - Wikipedia
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.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

Environmental Risks From Mine Tailings
8/10/2018· Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings.
