The geology, petrography and chemical variation of the Pecket coal sequence, Magellan Region (52_x0001_57VS, 71_x0001_10VW), the only Chilean coal used for electricity generation on a large scale, has been studied in order ...

Introduction: Investigations in Colombia about work and health conditions in coal mining are scarce and few have focused on the perception of the exposed population and their behaviors in response to inherent risks. ...

Mining activities can increase the mobility of metals by accelerating the dissolution and leaching of minerals from the rocks and tailing piles to the environment and, consequently, their availability for plants and ...

Brazil produces about 37 million cubic meters of charcoal per year whit an increasing due to the gradual coal replacement, once the coal mined in Brazil does not have adequate levels of carbon for some purposes, such as ...

Reactive oxygen species and nitrogen species have been implicated in the pathogenesis of coal dust-induced toxicity. The present study investigated several oxidative stress biomarkers (Contents of lipoperoxidation = TBARS, ...

The Petrobras produced green petroleum coke (GPC) is a carbon rich fuel, virtually ash-free, with low sulfur content, and is a fuel suitable to replace metallurgical coke in blast furnaces. The GPC was tested in a pulverized ...
