Designing gold extraction processes: Performance study of ...

2017-8-1  Marsden and House (2006) have suggested that after determining the gold mineral type, the ore composition, especially the concentration of gold, other valuable minerals, and minerals detrimental to processing, must be determined prior to gold process design. They also discuss the importance of gold grain size distribution and liberation ...
