As a technique of separation, flotation is seen to be especially significant to the economy of the industrialized world. Many common metals are tough and costly to extract since the high-grade ores that basic physical...
The response of Imogbara (Nigeria) gold ore to shaking tabling gravity separation methods was investigated in this research work. Gold concentration in run-off mines is usually as low as 0.005 ppm and must be upgraded...
The removal of metallic impurities from off-grade copper concentrate was investigated in alkaline solution with H2O2. The analysis results of XRD and SEM-EDS revealed the oxidative mechanisms of all sulfides. The infl...
Sulfation roasting was studied to extract copper from the copper sulfide concentrate. Sodium sulfite was added as sulfation agent to the copper sulfide concentrate during roasting in this study. Sulfur removal rate at...
Multiplicity of the chemical, biological, electrochemical and operational variables and nonlinear behavior of metal extraction in bioleaching environments complicate the mathematical modeling of these systems. This re...
The effects of ferrous and ferric iron as well as redox potential on copper and iron extraction from the copper flotation concentrate of Sarcheshmeh, Kerman, Iran, were evaluated using shake flask leaching examination...
