sima razmjouee; mahmood abdollahy; seyed mohammad javad koleini

Volume 3, Issue 2 , July 2012, Pages 99-102


  Using microflotation method, this study explored the collectorless flotation of Chalcocite and its dependence on the redox potential of pulp . Electrochemical studies were performed by cyclic voltammetry  in specific potential ranges and at different pH values. The results show that significant ...  Read More

Case Study
A new approach to define batch settling curves for analyzing the sedimentation characteristics

Mohammad Reza Garmsiri; Hassan Haji Amin Shirazi

Volume 3, Issue 2 , July 2012, Pages 103-111


  The results of batch settling tests (BST) are used to investigate settling behavior of solids suspension, which contribute to sizing thickeners. Conventional methods in analyzing BST on the basis of visual and graphical procedures lead to sub-optimally sized and selected thickeners. A computational approach ...  Read More

Case Study
Wellbore associated problems due to gas injection into non-horizontal structures

A Chamani; Vamegh Rasouli

Volume 3, Issue 2 , July 2012, Pages 113-119


  The rapid growth in natural gas consumption has increased the need for gas storage, in particular in the form of injection into depleted reservoirs. Also, CO2 sequestration into the depleted reservoirs has attracted a large attention recently. However, it is important to ensure that the injection pressure ...  Read More

Case Study
Identification of groundwater contamination sources of Lakan lead and zinc mine, Khomain, Iran

Feridon ghadimi; Mohammad Ghomi; Abdolmotaleb Hajati

Volume 3, Issue 2 , July 2012, Pages 121-134


  Altogether 20 groundwater samples were collected around the Lakan Pb and Zn mine in Iran. Samples were analyzed for 8 constituents including Fe, Pb, Hg, Mn, Zn, CN, SO4 and Cl using standard method. The results show that the average concentrations of constituents were 0.01, 0.60, 0.10, 0.01, 0.40, 35, ...  Read More
