Three well-known copper and gold deposits in northern Luzon, Philippines are located in the Mankayan Mineral District. These are the Lepanto Copper-Gold 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 pre-Eocene Lepanto...

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.

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.

Artificial gypsum from the dryer will be used at other cement grinding plants in the country. The 50t/hr dryer will be installed at the end of 2018 and is expected to start commercial operation in mid-2019. Gebr. Pfeiffer is also planning to partially calcine the gypsum in future installations of the dryer.

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 (e.g., Fig. 1a; Hudson-Edwards et al., 2001, Younger and Wolkersdorfer, 2004, Lottermoser, 2007).The word 'tailings' is generic as it describes the by-product of several extractive ...
David John Williams, in Ground Improvement Case Histories, 2015. Abstract. Mine tailings are typically silt-sized 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 ...

On August 1, 2012, a massive mining spill causing the release of 20.6 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.
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 cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
