With the rising gold prices in recent years, it further stimulated the rapid development of gold industry. As the exhaustion of highgrade gold ore, researching on middlelow grade and refractory gold ore and strengthen the traditional gold mining process undoubtedly have become the main trend in global gold beneficiation industry.
This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of preconcentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries.
