small-scale mining or small mines using modern, adapted technology and with required investment of $200,000 to $3 million.About 15% of gold exports from Zimbabwe in 1999 were estimated to come from small-scale mining (MMSD, 2001).

Artisanal and Small-Scale Gold Mining Without

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 pre-concentration and mill leaching, as they lead to the least amount of waste, a short processing time for miners, and high gold recoveries.
