[Chat Online]The gold pan is most commonly used to locate a richer paying area by sampling, so that larger production equipment can be brought into that location to work the ground to recover more gold There are stories in the old mining records about the ground being so rich during the 1849 gold rush that as much as 96 ounces of gold were recovered from a single pan
[Chat Online]Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration
[Chat Online]The most common and notable example of this are precious metal values (gold, silver etc) where the beneficiation process is applied directly on run-of-mine ores followed by the extraction of gold and in some cases silver as a relatively pure metal within the mineral processing circuit
[Chat Online]In all methods of gold ore refining, the ore is usually washed and filtered at the mine, then sent to the mill At the mill, the ore is ground into smaller particles with water, then ground again in a ball mill to further pulverize the ore
[Chat Online]Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore Mining 1 In lode or vein deposits, the gold is mixed with another mineral, often quartz, in a vein that has filled a split in the surrounding rocks
