A method and plant for gold recovery from any goldbearing ore by lowtemperature chlorination, wherein the finelydivided goldbearing feedstock is chlorinated gaseous chlorine at a temperature of about 245#176; C. to form a highly volatile chloride compound, which after leaving a reactor is directed to a lowtemperature nitrogen plasma unit having a temperature of #176; C., wherein the
The closest to an apparatus for extracting gold from ore is the setting for leaching gold infiltration (Plaksin, I. N. Metals precious metal, M. GNTI literature on ferrous and nonferrous metallurgy, 1943, S. 194 204, Fig. 121).
#0183;#32;Prospecting for gold can be a fun hobby, though its a lot of work! You may be able to harvest gold flakes from rock if it contains gold among its minerals. The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if youre able to obtain some, though this is dangerous.
A process for extracting metals having lead affinity from mineral ores. The process is in steps including, pulverizing the ore material, drying the ore, melting elemental lead in a melting chamber and maintaining the molten lead within a preselected temperature range, introducing the ore into the lower portion of the melting chamber, agitating the molten mixture, transferring the molten
For extracting gold from lowgrade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide as laid out in the International Cyanide Code. Gold refining

Gold extraction from its ore ascorix how is gold extracted from its ore quora excluding mechanical smelting and amalgamation processes the methods of extracting gold from its ores may conveniently be grouped together under the heading of wet or chemical methods in these the gold is dissolved by some suitable solvent a
Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold
