EXTRACTION OF LEAD FROM GALENA CONCENTRATES

Extraction Of Lead From Galena Concentrates

A study on lead extraction from lead concentrate had been conducted. Galena is usually associated with other sulfideores such as sphalerite.The lead concentratewas able to be extracted and purified into its metal througha leaching process using a selective solvent fluosilicic acid H 2SiFof 6.

Extraction of lead from electrolytic manganese anode mud

Extraction Of Lead From Electrolytic Manganese Anode Mud

Apr 05, 2021 In this work, extraction of lead from Electrolytic Manganese Anode Mud EMAM by microwave coupled ultrasound was studied. The results showed that microwave roasting promoted the conversion of MnO 2 to Mn 2 O 3 and Mn 3 O 4, which greatly facilitated the subsequent leaching process of lead and the introduction of ultrasound effectively enhanced the leaching process.
