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 ...

The transition from artisanal mining to small-scale mining produces an increase in productivity and financial gains for capital owners (see Bikubanya & Radley in this issue). More and more, the means of production are in the hands of small-scale mining companies or miners' cooperatives (see Dunia & Geenen in this issue).

This study aimed to determine levels of cyanide (CN) pollution in the soil and surface water at selected mining sites of Mbeya region. A total of (n = 124) samples were collected and analyzed by spectrophotometry. The cyanide levels of soil-based samples and water-based samples at Mwasenga, and Ifumbo mining sites were above the permissible limits.

The shift to sodium cyanide. Sodium cyanide is more efficient in processing lower-grade gold ore than mercury is. According to Joshua Boiwo, geology officer for Migori county in south-western Kenya, 'Using mercury can get between 25% and 50%, maximum 60% of gold, but with cyanide, you get 95% or even of gold from ore.' 3 This means that piled 'tailing' …
