A 200 TPH (tons per hour) diamond processing plant involves various stages and equipment designed to extract and process diamonds efficiently. Here are the key components and stages typically involved in such a plant:
Primary Crushing: This stage reduces the size of the run-of-mine ore into manageable pieces for further processing. Jaw crushers or gyratory crushers are commonly used.
Screening: After crushing, the material is screened to separate fine particles from larger ones. Vibrating screens or rotary screens are typically used.
Secondary Crushing: Oversized material from the screening process may need further reduction. Cone crushers or impact crushers can be used here.
Scrubbing: This process removes clays and other deleterious materials from the ore. Scrubber drums or log washers are typically used.
Dense Media Separation (DMS): A key process for diamond processing, DMS separates diamonds from other materials using a medium with a specific gravity that allows diamonds to float while heavier waste sinks.
Recovery: This stage involves the concentration and recovery of diamonds from the DMS concentrate. Jigs, X-ray sorters, grease belts, or other specialized diamond recovery technologies are used.
Final Sorting and Classification: Once the diamonds are recovered, they are sorted and classified based on size, quality, and other factors. Manual sorting and automated sorting technologies can be used here.
Tailings Handling: The waste material after diamond recovery is managed, often sent to tailings storage facilities for environmentally responsible disposal.
Each processing plant might have specific variations in the above process, depending on the particular characteristics of the ore and the desired quality and quantity of the final product.
If you're seeking more detailed information on constructing such a plant, including costs, design considerations, and specific equipment recommendations, consulting a professional in mining engineering or a specialized company in diamond processing would be advisable.
