A 0.5 tph (tonnes per hour) portable hard rock gold processing plant is a mobile facility designed to extract gold from hard rock ores. Such a plant typically includes various equipment components tailored for gold extraction, including:
- Jaw Crusher: To crush hard rock into smaller pieces.
- Ball Mill: To grind the crushed rock into fine powder.
- Concentration Equipment: This can include gravity concentrators like jigs, shaking tables, and sluice boxes which are critical for recovering gold from the ore.
- Centrifugal Concentrator: For fine gold recovery which may be missed by gravity concentrators.
- Flotation Cells (Optional): If the gold is associated with sulfides, flotation cells can be used to separate gold from the sulfide material.
- Water Supply System: Necessary for the washing and concentration processes.
- Diesel Generator: To power the entire system if a grid connection is not available.
- Control System: For managing and monitoring the plant operations.
- Conveyor Belts: For material transportation between different stages of the plant.
The major advantage of such a portable plant is its mobility, allowing miners to move it closer to ore sources and thus, reduce transportation costs and improve efficiency. The small-scale nature (0.5 tph) makes it suitable for small mining operations or as a preliminary testing plant. These plants are designed to be user-friendly, with features that facilitate ease of maintenance and operation.
