Comparison of different gold recovery methods with regard to pollution control and efficiency

• This case study performed at the largest gold mining village in the Philippines compares four methods for gold recovery: amalgamation, cyanide leaching, a shaking sluice, and Cleangoldm sluices. The results show that a combination of manual panning or Cleangoldm sluices followed by cyanidation is the best solution under present conditions, followed by cyanidation alone. Based on the knowledge obtained, remarks on suitable policy actions, which may be applied also in other gold fields, are made.
