Abstract

Kinetics of advanced oxidative leaching of pyrite in a potassium peroxy-disulphate solution

Highlights

  • Pyrite is one of the most common sulphide ores, and is an important carrier of gold, silver, and platinum (Gu et al, 2010)

  • Pyrite had a regular crystal habit prior to leaching, but exhibited faviform holes after leaching. These results provide a basis for effective leaching of gold from gold-bearing pyrite ores using the advanced oxidative leaching system

  • Gold contained in micro-disseminated gold deposits is typically encased in pyrite, such that the gold is physically shielded and thereby difficult to react with the leaching agent

Summary

Introduction

Pyrite is one of the most common sulphide ores, and is an important carrier of gold, silver, and platinum (Gu et al, 2010). Effects of K2S2O8 concentrations on pyrite leaching Figure 2 displays the effect of K2S2O8 concentration on pyrite leaching at a pyrite concentration of 10 g/L, temperature of 70°C, stirring rate of 500 r/min, and a pyrite particle size of 0.075– 0.045 mm.
