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 Process of Lead and Variations of

Metallic lead has been extracted by roasting process. The result displays that galena is still in present in the matt despite of exposure to high temperature, over .

Diagnostic leaching of galena and its oxidation products

2002-7-1  Continued extraction of lead with increasing conditioning time is due to continued galena oxidation, not to the extraction of lead from galena. Argon gas purging minimises this oxidation whereas the use of air or nitrogen gas purging do not. Using information gathered from these experiments, an improved EDTA extraction technique was developed

2011-6-1  Batch experiments with the lead sulphide ore mineral galena were carried out in order to get information about the oxidation mechanisms and to contribute to the

Factorial Analysis of Lead Bioextracted Using Mixed

2020-8-21  This paper presents lead bioextraction using mixed cultures of Acidithiobacillus Ferrooxidans (ATF) and Acidithiobacillus Thiooxidans (ATT) on galena. The effect of leaching time at constant leaching temperature and ore mass-input were investigated. X-ray diffractometry (XRD) analysis of the galena used was carried out to evaluate the phases in the ore.

Continuous leaching and separation of Pb in CH3COOH

2020-6-1  Three cycle experiments of galena and sphalerite electrolytes were investigated. It can be seen from Table 3 that after three cycles of experiments, the recovery of lead and zinc did not decrease and was basically consistent with the previous one. The pH of the electrolyte solution was tested each time and the result was always 5.7.

Kinetics and mechanism of the bacterial and ferric

2004-11-1  The galena bio-oxidation experiments demonstrated considerable acid consumption, because of occlusion of the produced elemental sulphur by precipitated lead sulphate. This reveals a new mechanism through which galena oxidation may hinder the bioleaching of other sulphide minerals.

Galena surface reactivity at acidic pH and 25 °C based on

2005-1-25  A study of (PbS) galena dissolution at acidic conditions was carried out by means of nonstirred flow-through experiments, in situ and ex situ Atomic Force Microscopy (AFM) experiments, X-ray photoelectron spectroscopy (XPS) surface analysis, and X-ray diffraction (XRD) patterns of the reacted surfaces. The nonstirred flow-through experiments were performed at pH 3, 25 °C, and
