Discovery of Yanshanian K-feldspar Granite in Huitongshan Copper Deposit, Gansu Province, and Its Implication;

The Investigation of Wild Morel Resources in Huishan Mountain and Qipanshan Mountain Areas of Shenyang;

Study on preparation of nanometer copper from chalcocite with acide acetonitrile-copper chlorination system;

Leaching of copper from chalcocite with acidic acetonitrilecopper sulphate system was studied.

The influential factors of bioleaching of digenite concentrate collected from Zijinshan copper mine with bacteria were investigated.

The digenite occurs as the lamellae or lens in the djurleite.

By emp loying EPMA and SEM techniques we examined the compositions of nucleus, cell-walls and cells of wood-cytoplasm in chalcocite and digenite and the shapes of wood cells.

Based on the optical microscopy, electron microprobe studie s and X-ray powder diffraction analysis it is revealed that the djurleite and dig enite are freguently found in copper ores of Dongxiang Copper Mine, Jiangxi Prov ince.
