Mineral processing technologies used to obtain valuable components of the solid wastes from coal combustion in power plants [PDF]

open access: yesActa Montanistica Slovaca, 2005
This paper presents mineral processing technologies used to achieve components from solid wastes of coal combusted in power plants. By combusting bituminous coal in smelting boilers, mineral novelties are formed which are separable by suitable mineral ...

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

open access: yesArchaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Pyrite recovery mechanisms in coal flotation

open access: yes, 1997
In most operating coal-cleaning plants, a significant amount of pyrite is recovered in the froth during flotation of high-sulfur coal. This pyrite recovery is commonly believed to be a result of pyrite particles floating due to hydrophobicity.

Banks and the economy: Evidence from the Irish bank strike of 1966

open access: yesThe Economic History Review, EarlyView.
Abstract This paper studies the macroeconomic impact of the Irish bank strike of 1966, which led to the closure of the major commercial banks for 3 months. We collect a variety of new evidence, such as high‐frequency macro data, economic forecasts, micro data and narrative sources.

The flotation of pyrite using xanthate collecters [PDF]

open access: yes, 1986
Bibliography: leaves 117-123.The flotation properties of pyrite were found to be significantly influenced by variations in the pH. In acidic solutions the pyrite floatability is very high, and recoveries of 95% could be achieved using only a frother.
