A 15tph (tons per hour) tailings lead and barite extraction process involves several key steps to effectively recover lead and barite from mining tailings. The process typically includes:
Screening and Classification: The tailings are screened to remove larger particles and debris. The material is then classified by size to ensure uniform feed to the extraction processes.
Crushing: The tailings may be crushed to liberate lead and barite particles from the gangue material. This step helps in achieving better separation in the subsequent processes.
Grinding: The crushed material is ground to a finer size to enhance the liberation of lead and barite particles.
Gravity Separation: Processes such as jigging, spiral concentrators, and shaking tables are employed to separate lead and barite based on their specific gravities.
Flotation: This process involves adding chemicals to the ground material to create froth. Lead and barite particles attach to the bubbles and rise to the surface, where they are collected.
Magnetic Separation: If any magnetic impurities are present, they can be removed using magnetic separators to ensure the purity of the final lead and barite concentrates.
Thickening and Dewatering: The concentrated lead and barite slurry is thickened and dewatered to reduce moisture content, making it easier to handle in subsequent processing or transportation.
Tailings Management: The remaining material, now as processed tailings, is managed properly to minimize environmental impact. This may include tailings ponds or dry stacking.
Quality Control and Sampling: Regular sampling and analysis are conducted to ensure the quality and consistency of the extracted lead and barite.
Employing these processes in a 15tph facility requires careful planning and integration of each step to achieve optimal recovery rates and product quality.
