Investigating possibility of replacing some chemical reagents used in sulfide copper flotation with halophilic bacteria

Amir Mohammad Nasrollahzadeh Bafti; Mohammad Jahani Chegeni; Ahmad Moghooeinejad; Zahra Manafi

Volume 14, Issue 1 , January 2023, , Pages 243-258


  Flotation is the most important method for processing sulfide copper ores. Due to the high cost and environmental hazards caused by the chemical reagents used in this process (collectors, frothers, pH regulators, depressants, etc.), the possibility of replacing all these reagents or at least some of ...  Read More

Bio-flotation of Chalcopyrite using Halophilic Bacteria Separately and Their Combination as Pyrite bio-Depressant

Amirmohammad Nasrollahzadeh; Mohammad Jahani Chegeni; Ahmad Moghooeinejad; Zahra Manafi

Volume 13, Issue 4 , October 2022, , Pages 1119-1138


  Due to the increasing consumption of lime in the flotation process to increase the pH of the system and create an alkaline environment, as well as its gradual increase in cost, the attention of researchers has been drawn to perform flotation operations in a neutral environment. Halophilic bacteria have ...  Read More
