of metals from waste button cell batteries was explored in this study. Aspergillus niger spent medium was used for metal to avoid toxicity of metals toward microbial cells. parameters including time, temperature, shaking speed, and volume of the spent medium were optimized. We obtained 100% of zinc and in six hours at 60 °C and 100 rpm using 15 mL ...read more
Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores.Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy.read more
