5 Gold Extraction Methods to Improve Your Recovery Rate

2021-7-12  The beneficiation stage is a crucial part of gold extraction during the whole gold ore processing plant. Placer gold mine and rock gold mine are most widely processed to extract gold concentration. Placer gold ore with high gold content mostly exists in the form of particles. Therefore, the ideal method to process placer gold ore is gravity separation.
