Abstract
The contact electrification of coals from France, the Great Britain an d the United States has been studied. Additionally, the behavior of th e most abundant minerals in coal (quartz, calcite and pyrite) has been investigated. The charge transfer upon repeated contacts with a coppe r plate has been measured. The study covers the influence of the miner al content, relative humidity, temperature and gas pressure on the ele ctrification behavior.
