Small Portable Gold Process Plant
This arrangement and flowsheet of a Mini Portable Gold Processing Plant permits several mineral separations by flotation and provides for the possible recovery of other minerals by gravity concentration The flowsheet is ideal for a pilotplant in field testing of ores to determine the economic feasibility of an ore deposit prior to the installation of a larger plant or for processing ore The process of treating gold ore to extract gold (and silver) and, therefore, produce bullion is called milling The building housing the process is called a mill The finely pulverized material that is rejected from the mill after the gold has been extracted is called tailingsGold and Tailings: The Standard Mill at Bodie, California Here is an Ancient Gold Ore Milling Process used in China in the 1800s We might use it again after WW3 At the time, 1890, the Author said “There is, of course, nothing for us to learn from this imperfect and rudimentary goldextraction process described here, which is doubtless destined to disappear ere long, before the progress of scientific mining, now making itself slowly felt Gold Milling Process Primitive and Basic
