Experimental research on recovering copper and gold from the copper-gold ore with heap leaching technique in Longnan

Present situation and developmental trend of pretreatment and l eaching technology for refractory copper-bearing gold ores;

Gold leaching of copper-bearing gold ore by ammoniacal cyanide process and its industrial practice;

Tongshi gold field is located around Tongshi alkaline igneous sub-volcanic complex in the west Shandong province of China.

Tongshi gold field are mainly composed of cryptoexplosive rock type (Guilaizhuang type), stratified microdisseminated carbonate rock type (Mofanggou type), multiple scarn type, porphyry type and altered rock type deposits (spot); the major mineral is gold, companied with silver, cooper and iron mineralization which formed a completed ore-forming series.

In this paper, the analysis is made of the comprehensive information features of the gold-forming geological background of the Tongshi gold field; then a detailed investigation is presented into the component znation tr.

Chinkuashih gold (copper) deposit is a high-sulfur type mesothermal-epithermal deposit which is closely related to Cenozoic Chilung volcanoes in the northern volcanic province of Tai-wan.
