Rock Crushing methods and How to recover gold from Ores

Gold is often found associated with the mineral quartz. It is sometimes associated with other minerals as well, including iron and manganese oxides, calcite, pyrite and other sulfides as well. It is not uncommon for prospectors, especially those who operate metal detectors, to find a rich gold bearing specimens of ore.. Sometimes the best use of these minerals is to sell them at specim

 · If the ore contains more coarse gold, it must be pre-selected because the coarse gold is in the cyanide solution It is difficult to dissolve, and it is difficult to recover by flotation. When the surface of the gold particles is clean and there are no harmful ingredients in the ore, the amalgamation method is more effective than the heavy separation method.

Bristol

Mining activity ended in 1893 and Bristol declined until 1900, when a leaching plant was built to recover copper from the ore, but that endeavor was not very successful and Bristol declined. The discovery of the Jack Rabbit District on the eastern slope of the Bristol Mountains is attributed to the locator picking up a rock to throw at a jackrabbit and finding it to be high grade silver ore.
