Processing The Gold Ore The Method Cheap

Free-milling gold can be further classified into low grade and high grade which helps determine the most economical and optimal gold recovery method. Low Grade. Low grade free-milling gold deposits contain less than 1 g t of gold. This low grade ore is crushed and heap leached to recover the gold. While heap leach recoveries are lower than in.

The Process Mineralogy Of Gold: The Classification Of Ore

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold ( 10 m) locked.

Heap Mining Efficiently Leaches Lower Grade Gold From S

As a rule of thumb, one gram per ton of ore can make a profitable heap leach mine. At a 75 gold recovery, it takes 41 tons of ore on the pad to recover one ounce of gold. However, all the material in the mine is not ore. Most mines will have 2-3 tons of waste material to 1 ton of ore. This waste must be taken to a separate dump.
