\n– Ball Mills\/Rod Mills: Ore is ground into fine particles to liberate gold from the host rock.
\n– SAG Mills (Semi-Autogenous Grinding): Used for harder ores to achieve finer particle sizes.<\/p>\n
A gold mining ore processing line is a series of steps designed to extract gold from raw ore efficiently. The process varies depending on the type of ore (e.g., free-milling, refractory, or placer deposits) but generally includes crushing, grinding, gravity separation, flotation, cyanidation (or alternative leaching methods), and refining.<\/p>\n
Here\u2019s a detailed breakdown of a typical gold ore processing line:<\/p>\n
—<\/p>\n
1. Crushing & Screening
\n– Primary Crushing: Large chunks of ore are reduced using jaw crushers or gyratory crushers.
\n– Secondary\/Tertiary Crushing: Cone crushers or impact crushers further reduce the ore to smaller particles.
\n– Screening: Vibrating screens classify the crushed material for optimal grinding.<\/p>\n
2. Grinding (Milling)
\n– Ball Mills\/Rod Mills: Ore is ground into fine particles to liberate gold from the host rock.
\n– SAG Mills (Semi-Autogenous Grinding): Used for harder ores to achieve finer particle sizes.<\/p>\n
3. Gravity Separation (Optional but Common)
\n– Used for coarse free gold recovery before leaching.
\n– Methods:
\n – Shaking Tables
\n – Centrifugal Concentrators (Knelson\/Falcon)
\n – Jigs & Sluices<\/p>\n
4. Flotation (For Sulfide Ores)
\n– Froth flotation separates gold-bearing sulfides from waste rock.
\n– Chemicals (collectors, frothers) help gold adhere to air bubbles for recovery.<\/p>\n
5. Leaching & Gold Extraction
\n# (A) Cyanide Leaching (Most Common)
\n– CIL (Carbon-in-Leach) or CIP (Carbon-in-Pulp):
\n – Ore slurry is mixed with sodium cyanide (NaCN), dissolving gold.
\n – Activated carbon adsorbs dissolved gold from the solution.
\n – Loaded carbon is processed further for gold recovery.<\/p>\n
# (B) Non-Cyanide Alternatives
\n– Thiosulfate Leaching (for refractory ores or eco-sensitive areas).
\n– Chlorination or Bioleaching (less common).<\/p>\n
6. Gold Recovery
\n– Electrowinning: Gold is stripped from carbon and plated onto cathodes.
\n– Smelting: Gold concentrate is melted with fluxes to remove impurities, producing dor\u00e9 bars.<\/p>\n
