and preg-robbing capacity of activated carbon, which was used as a substitute of carbonaceous matter in carbonaceous gold ores, was studied. After 14 d treatment with Phanerochaete chrysosporium... capacity of activated carbon by 12.88%. This indicates that Phanerochaete chrysosporium is an available microorganism, and it can be employed to reduce the preg-robbing capacity of carbonaceous matter......
because dissolved aurocyanide complex is robbed by adsorption of carbonaceous matter, and this phenomenon is termed preg-robbing [3-5]. The famous carbonaceous refractory gold ores include the Carlin gold... an important problem facing the gold industry. 2 Composition and preg-robbing behavior of carbonaceous matter The carbonaceous gold ores mainly exist in the form of composite minerals......
leaching process, and the degree of the preg-robbing effect depended on the content of carbonaceous matter and its existence forms [29-31]. Due to the preg-robbing effect, the gold in the form of gold... 0.22% and 0.25%, respectively, while no carbonaceous matter existed in the calcine as shown in Table 4. Therefore, the preg-robbing effect of carbonaceous matter on gold leaching for the dust......

pretreatment. Since the carbonaceous matter in concentrate possesses a strong capability of preg robbing, the cyanidation process is not suitable for the extraction of gold after pretreatment. However... in the refractory ores, it could be more difficult for the extraction of gold[3-6]. Under many conditions, the carbonaceous matter in refractory ores could possess a strong capability of preg robbing[7-9......
]. The lithology of the lower ∈1n in Well Ciye 1 is mainly black shale, carbonaceous shale, stone coal and siliceous shale, which is rich in carbonaceous matter, siliceous matter and pyrite. The w(TOC... siliceous shale and carbonaceous shale, and the organic matter well develops. The w(TOC) of shale with depth of 790-857 m is 4.03%-31.50%, with an average of 15.0%. The upper ∈1n is composed......
