Optimization of Process Parameters for Enhanced Up-gradation of Qilla Saifullah Copper ore through Froth Floatation Technique

M. Ibrahim; N. Mohammad; Z. Ahmad; Sh. Bacha; N. Muhammad Khan; M. Iftikhar Khan

Volume 12, Issue 3 , July 2021, , Pages 633-649


  In this work, we focus on the up-gradation of the copper ore of Qilla Saifullah in Pakistan through the froth flotation technique. The chemical analysis of the head copper ore sample reveal the presence of 2.85% Cu, 22%  Fe2O3, 52.9% SiO2, and other minor minerals. The optimum grinding time and ...  Read More

Prediction of Acid Mine Drainage Generation Potential of A Copper Mine Tailings Using Gene Expression Programming-A Case Study

B. Jodeiri Shokri; H. Dehghani; R. Shamsi; F. Doulati Ardejani

Volume 11, Issue 4 , October 2020, , Pages 1127-1140


  This work presents a quantitative predicting likely acid mine drainage (AMD) generation process throughout tailing particles resulting from the Sarcheshmeh copper mine in the south of Iran. Indeed, four predictive relationships for the remaining pyrite fraction, remaining chalcopyrite fraction, sulfate ...  Read More

Comparison of Copper Dissolution in Chalcopyrite Concentrate Bioleaching with Acidianus Brierleyi in Different Initial pH Values

M. R. Samadzadeh Yazdi; M. Abdollahi; S. M. Mousavi; A. Khodadadi Darban

Volume 11, Issue 3 , July 2020, , Pages 753-764


  Although bioleaching of chalcopyrite by thermophilic microorganisms enhances the rate of copper recovery, a high temperature accelerates iron precipitation as jarosite, which can bring many operational problems in the industrial processes. In this research work, the bioleaching of chalcopyrite concentrate ...  Read More

Exploring mechanism of xanthate adsorption on chalcopyrite surface: An atomic force microscopy study

R. Ahmadi; E. Ravanasa; Y. Mirzapour

Volume 9, Issue 4 , October 2018, , Pages 1009-1018


  In this work, adsorption of the potassium amyl xanthate collector on the pure chalcopyrite surface was studied by applying atomic force microscopy (AFM). The adsorption experiments were carried out at different concentrations of the collector and at diverse pH values in the presence or absence of exterior ...  Read More
