Abstract
CHEMICAL AND MINERALOGICAL STRUCTURE OF ANORGANIC MINERAL SUBSTANCE FOUND IN KONIN BROWN COAL (Central Poland)The author has investigated an anorganic mineral substance found in the brown coal of outcrop Niesłusz at Konin in Central Poland. He succeeded in identifying this substance by means of combined methods, consisting of the chemical and microscopic examination of the ashes of the discussed coal types and of the chemical investigation of the anorganic saIts appearing in the crude co al.The ashes had been obtained from coal dried at 105°C and burned at 550°C.
