Hard Rock Milling: A Matter of Scale
April 2013 by Chris RalphMost prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.
A treasure-seeking young man whose name will forever remain anonymous made the months-long journey either over land or by sailing ship to California after word spread about the gold strike in 1849.
NOI or POO for small backhoe
The first location we worked was a small, dry ravine cutting through many mineralized zones in an area where some hard rock mining had taken place in the past.
The operation and techniques employed are highly successful in producing free gold with minimal work involved while maintaining an environment protection process through the use of recycled water and a settling pond.
Each specimen is carefully examined to determine if it would be beneficial or not to use an acid treatment to reveal more of the gold.
Detecting is not very complicated and the rewards can be tremendous. The difference between success and fruitless toiling can be remedied by a few small adjustments and a whole lot of perseverance.
Modern-day placer miners have many advantages over the prospectors of the gold rush days. Our prospectors can reap many benefits from accumulated knowledge of the last 100 to 150 years, which is a long and impressive list.
