The equipment used in gold ore milling circuits is designed to efficiently extract gold from the ore and optimize the recovery process. Depending on the type of ore and the extraction method, the circuit may vary slightly, but generally, the milling circuit comprises the following key equipment:
1. Crushers
- Щелепні дробарки: Used for initial coarse size reduction of the raw ore.
- Ударні дробаркиабоКонусні дробарки: Reduce ore pieces further into smaller sizes suitable for grinding.
2. Млини для помелу
- Шарикові млини: Most common grinding equipment, used for fine grinding of the crushed ore.
- SAG (Semi-Autogenous Grinding) Mills: Often used in primary grinding for large-scale operations.
- Стовпчики для млинців: Sometimes used for finer grinding based on specific mining conditions.
3. Classifiers
- Гідроциклони: Separate fine particles from larger ones using centrifugal forces.
- Spiral Classifiers: Utilize gravity and water flow to classify particles.
- Екрани: Remove oversized material for reprocessing or secondary crushing.
4. Gravity Separation Equipment
- Jigs: Provide preliminary gold concentration by separating heavier gold-bearing material.
- Shaking Tables: Used for further concentration of gold from milled ore.
- Spiral Concentrators: Separate gold particles from lighter waste material.
5. Flotation Cells
- If the ore contains sulfide minerals or refractory gold, flotation cells are used to concentrate gold by separating it from sulfides.
6. Cyanidation Tanks
- Used in leaching gold from the ore as part of the carbon-in-leach (CIL) or carbon-in-pulp (CIP) process.
7. Thickeners
- Thicken slurry to remove excess water before leaching or tailings disposal.
8. Activated Carbon Systems
- Carbon columns or carbon tanks extract gold from the cyanide solution.
9. Filtration and Drying Systems
- Filter Presses or vacuum filters remove moisture and prepare dried concentrate for smelting.
10. Smelting Furnaces
- Additionally, furnaces are often part of the final stage in processing, where purified gold is melted into bars.
11. Auxiliary Equipment
- Equipment such as conveyors, storage bins, feeding systems, chemical dosing pumps, automation controls, and water recycling systems complement and support the milling process.
The exact equipment and configuration of a gold ore milling circuit depend heavily on the type of ore, the size of the operation, and the target recovery rates.
