What Are the Methods for Gold Processing
2. Gravity Separation (Amalgamation)-Cyanidation Leaching Combined Method. This kind of gold processing method is suitable for the gold-containing oxidized ore of quartz vein type with uneven grain size and deep oxidation. The kind of ore should be basically free of elements such as copper arsenic and antimony.

5 Gold Extraction Methods to Improve Your Recovery Rate
For placer gold ore with specific gravity ≥1.25 the process can minimize the gold particle size to 0.04mm. Can process coarse metal minerals with 0.007mm-50mm in size. For placer gold processing with specific gravity difference ≥1.25 and ore monomer dissociation the minimum particle size can reach 0.04mm.

Gold is extracted from ore into a solution by a heap leaching process using two heap leaching pads (HLPs)a primary and a secondary. Heap leach feed consists of crushed ore (116.9M t at 0.78 g/t Au) conveyed to the HLPs as well as run-of-mine (ROM) un-crushed (32.1M t at 0.22 g/t Au) ore which is hauled directly to the HLP for leaching.

However at about half of the heap leaching operations ore is crushed and agglomerated prior to placement on the heap to increase permeability of the heap and maintain the high pH needed for leaching to occur (Bureau of Mines 1986). Agglomeration entails mixing the crushed ore with portland cement lime ash or other materials.
