Estimation of Copper in Copper Ores Collected from Jangkot Rolpa, Nepal
(2024-06) Rajaure, Anil; Dr. Deval Prasad Bhattarai
Nepal is a country rich in natural resources. There is evidence of the presence of mines of different types of elements, but scientific research in this field is found to be less. Zinc, iron, copper, etc. are the major sources of mines here which have been extracted since time immemorial. But these days, significant research and extraction of such minerals have not been found to occur. In this context, it seems desirable to study and research the mines available in Nepal. In this study, five samples of copper ores were collected from Jangkot Rolpa and examined using Titrimetric analysis, atomic absorption spectroscopy and x-ray diffraction (XRD) methods. The results show that sample C1RJ has the highest copper concentration (2.20% by titration and 1.64% by AAS) among the test samples, indicating that the collected samples contain extractable amounts of copper in that location. The XRD results confirms the ores are auzurite, malachite, cuprite and chalcocite. However, further research is required to carry out the quality of the copper deposit.
