Production of reagents for mineral processing to recover gold, copper, zinc andIntroduction to Mineral Processing or Beneficiation,12-01-2018· These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media. However, one the challenges with AG mills is that properties, such as hardness and abrasiveness, of the ore can vary, resulting in inconsistent grinding behaviour.(46) Operational Stamp Mills in the USA (update 9/2016),The stamp mill is at the Crisson Gold Mine in Dahlonega, Georgia. The mine was established in 1847 and was worked commercially until the early 1980s. The operation was opened to the public in 1969. The 10-stamp mill crushes the ore through a hand fed method, and it goes onto the sluice table to a catch basin and then is panned out.
