[en] Sor-Range coal was demineralized with HCl and the trace elements present in the acid extracts were determined by atomic absorption spectrophotometer. The effect of time of equilibration and that of the acid concentration was studied. It was found that increasing reaction time and concentration of hydrochloric acid, generally has increasing effect on the extraction of trace elements. Calcium and magnesium were found to be extracted in the higher amounts, while zinc and potassium has been extracted in the least amounts. The percent extraction of most of the trace elements with HCl solution show a considerable increase compared to that with water. (author)
