Tailings are mixtures of crushed rock and processing fluids from mills, washeries or concentrators that remain after the extraction of economic metals, minerals, mineral fuels or coal from the mine resource (, Fig. 1a; HudsonEdwards et al., 2001, Younger and Wolkersdorfer, 2004, Lottermoser, 2007).The word ''tailings'' is generic as it describes the byproduct of several extractive ...

CertainTeed mines gypsum rock from an open pit quarry located approximately miles SouthSouthwest of the manufacturing facility. Mining is currently limited to 1,860,000 tons of gypsum rock per twelvemonth rolling period. The gypsum ore lies in three dominant seams each separated by varying thicknesses of overburden.
The Wanshan area is presently suffering from the effects of Hg mining for more than a 1000 years; a large volume of tailings and mine waste calcine from ore processing and retorting have been stockpiled in the valley, typically in the vicinity of headwater streams.

The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment. Calcination is carried out in furnaces or reactors (sometimes referred to as kilns or calciners) of various designs including shaft furnaces, rotary kilns, multiple hearth furnaces, and fluidized bed reactors.
David John Williams, in Ground Improvement Case Histories, 2015. Abstract. Mine tailings are typically siltsized materials derived from mineral processing, which are conventionally pumped as an aqueous slurry, thickened tailings, or a tailings paste to a surface tailings storage facility (TSF). After discharge, an aqueous tailings slurry forms a wet, soft delta, while thickened and paste ...

The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.

Three wellknown copper and gold deposits in northern Luzon, Philippines are located in the Mankayan Mineral District. These are the Lepanto CopperGold Deposit, the Far Southeast Porphyry Copper Deposit and the newly discovered Victoria Gold Deposit. The latter discovery led LCMC to shift from a predominantly copper mine to a gold mine. The preEocene Lepanto...

On August 1, 2012, a massive mining spill causing the release of million tons of toxic tailings into water bodies, occurred at the Philex Padcal mine, located in Benguet province. In terms of volume, the spill was ten times larger than the unprecedented 1996 Marcopper mine disaster.
From 1953 to 1976 the nearby Palawan Quicksilver Mine used mine tailings from their ore extraction processes to produce a jetty at Honda Bay. The village of Sitio Honda Bay was erected on these mine tailings. Environmental studies indicate that some residents of the village and elsewhere near the mine have toxic levels of mercury in their blood.
AECOM has performed gypsum stack operations and maintenance services in southeast Ido for nearly 40 years. This project – the Million Impoundment construction and maintenance for sluiced gypsum and wash water waste streams – is the latest. The work includes siphon cell construction and operations for slurry dewatering; cut/fill scraper and dozer operations in [.]
