Chemiczno-mineralna budowa nieorganicznej substancji mineralnej w węglu brunatnym z Konina
Abstract
CHEMICAL AND MINERALOGICAL STRUCTURE OF AN ORGANIC MINERAL SUBSTANCE FOUND IN KONIN BROWN COALPart II. Investigations of the Anorganic Mineral Substance (Central Poland)In this paper the author reconstructs the chemical composition of the anorganic mineral substance from 6 examined samples (Table 4); the mineral composition of this substance he presents on Table 5. It appears from this table that the composition of the anorganic mineral substance in the investigated coals comprises: halite, rarely sylvine, hydrated sulphates of sodIium, potasium, magnesium, iron and calcium, melnikovite, calcite, salts of calcium and magnesium humic acid, silica-alumina gels, opal, phosphates (phosphorite ?); pyrite (marcasite), haloisite, clinochlore, orthoclase, albite, quartz, elementary sulphur (?), as well as heavy minerals such as zircon and rutile.The author has mot investigated which trace elements are contained in the substance.The presented mineral composition is not uniform throughout the horizons; it shows changes, both vertically and along its strike (Tables 4 and 6).Owing to their content of NaCI and KCl, the coal types from outcrop Niesłusz at Konin should in the strict sense of this expression, be considered to be salt coals. However; the salt content is so small that, for all practical purposes, these coals may be looked upon as being saltless, - the more so since they do not contain any salts of sodium nor potassium of humic acid which are no less harmful than are chlorides.Downloads
