Investigation on selective rhenium leaching from molybdenite roasting flue dusts

The possibility of selective leaching process was investigated during molybdenite flue dust leaching to recover its rhenium content. The results show that addition of alcohols to water makes the medium less favorable for molybdenum transfer into aqueous phase. On the other hand, addition of small amounts of alcohols (5-15%) makes a noticeable separation of rhenium over molybdenum, but by increa...

Extraction of Iron and Manganese from Pyrolusite Absorption Residue by Ammonium Sulphate Roasting–Leaching Process

The residue from desulfurization and denitrification of exhaust gas treatment process with pyrolusite ore as absorbent is regarded as a potential source of iron and manganese. In this study, an extraction process is proposed for recovery of iron and manganese with ammonium sulphate roasting followed by sulphuric acid leaching. Firstly, the conversion mechanism was analyzed through mineral phase...

Poly (Butylene Succinate) Scaffolds Prepared by Leaching

Biomaterials are the main focuses of scientists’ efforts to develop new materials to replace or repair bone tissues [1]. Biomaterials are natural or synthetic materials which can interface with biological systems allowing the increase, repair or even the replacement of tissues and organs of the human body [2]. Within biomaterials, the polymers can be natural or synthetic as well. The main polym...

Vanadium extraction from a magnetite ore using alkaline roasting and acid leaching processes: optimization of parameters by response surface methodology

In this work, thealkaline roasting and sulfuric acid leaching processes were employed to extract vanadium from the magnetite ore of Saghand mine in central Iran. The response surface methodology based on the central composite design model was applied to optimize the parameters involved in the processes. The studied roasting parameters were temperature (900-1100 °C), sodium carbonate percentage ...

Recovery of Copper from Copper Slag and Copper Slag Flotation Tailings by Oxidative Leaching

Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
