Gold Extraction & Recovery Processes
The practice of gold minerals beneficiation is optimized by using the information obtained from applied mineralogy. In this way, at the moment of development and select a process for treatment a gold ore, try to identify the gold minerals is the first step. Obviously, the detection of non-valuable minerals is important.
Introduction to Mineral Processing or Beneficiation
Grinding media can be steel rods, steel balls, hard pebbles or the ore itself. Autogenous and Semi-Autogenous Mills. Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations.
