Small Mining Operations
Shaker Tables for Processing Hard Rock Ores
May 2017 by Chris Ralph
Most placer equipment is really made with gold in the 30 and larger mesh sizes in mind, though if carefully used can often get reasonable recovery down to the 50 mesh size.
Modern Mining Reclamation
A study showed that between 1930 and 1980, only a quarter of one percent of the land in the United States was used in all mining applications combined, including surface mining, tailings disposal, underground mines, and all mineral processing facilities.
Romancing the Rock
With the exception of well-established operators with proven reserves and years of field experience, the high price of gold brought a flood of speculators, con men, and real estate brokers into the mix who were not previously engaged in the gold mining market.
Putting Together A Small Free Gold Mill
Most small-scale miners want to know how they can set up a system much more cheaply. The difficulty is in the balance of putting together a decent small-scale system at a reasonable cost.
Gold in Guyana—Part II: Process Optimization at Sacre Coeur Minerals' Lower Puruni Alluvial Mining Project
In Part Two of my two-part series I describe the mechanized alluvial gold mining operation on the lower Puruni River launched by Sacre Coeur Minerals in 2011.
The Bucking Room
Since this position was the least desirable due to the hard physical labor, the bucking room was used as punishment. Do you have a mediocre worker? Bad attitude? Off to the bucking room!
The Basics of Crushing and Milling Operations
In processing gold, silver and other valuable ores, the minerals containing the values, such as metallic gold, silver-bearing sulfides or other minerals, must be freed from the surrounding host rock before those valuable minerals can be captured.
The Giant King Mine
Most gold-bearing veins in this region are controlled by fractures associated with the Melones Fault, a late Cretaceous structure that is 108 to 127 million years old.
