A TPH (Tonnes Per Hour) gold processing plant is designed to extract gold from ore at a specific throughput rate. The design and equipment selection depend on factors like ore type, gold grade, recovery method, and environmental considerations. Below is a general outline of key components and processes for a typical gold processing plant:<\/p>\n
—<\/p>\n
1. Plant Capacity & Ore Characteristics
\n– Throughput: e.g., 50 TPH, 100 TPH, 300 TPH (customizable).
\n– Ore Type: Hard rock (lode gold), alluvial\/placer, or refractory ore.
\n– Gold Grade: Grams per tonne (g\/t) or ounces per tonne (oz\/t).
\n– Gangue Minerals: Presence of sulfides, quartz, or clay affecting processing.<\/p>\n
—<\/p>\n
2. Key Processing Stages
\n# (A) Crushing & Grinding
\n– Primary Crushing: Jaw crusher or gyratory crusher (for hard rock).
\n– Secondary\/Tertiary Crushing: Cone crusher or impact crusher.
\n– Grinding: Ball mill, rod mill, or SAG mill to achieve fine particle size (e.g., 75 microns for leaching).<\/p>\n
# (B) Gravity Separation (Optional)
\n– For free-milling gold: Shaking tables, centrifugal concentrators (e.g., Knelson\/Falcon), jigs.
\n– Recovers coarse gold before leaching.<\/p>\n
# (C) Leaching & Adsorption
\n– CIL (Carbon-in-Leach) \/ CIP (Carbon-in-Pulp):
\n – Ore slurry mixed with cyanide (NaCN\/KCN) to dissolve gold.
\n – Activated carbon absorbs gold from solution.
\n – Electrowinning recovers gold from loaded carbon.
\n– Heap Leaching (for low-grade ores): Ore stacked on pads and irrigated with cyanide.<\/p>\n
# (D) Flotation (For Sulfide Ores)
\n– Froth flotation to concentrate sulfide minerals before leaching.<\/p>\n

# (E) Refining
\n– Smelting of electrowinning sludge to produce dor\u00e9 bars (~90% purity).
\n– Further refining via aqua regia or Miller process for 99.99% purity.<\/p>\n
