: Maintain optimal air flow to form stable bubbles that can support coarse particles.
4. Reagent Optimization
جمع قىلغۇچىلار: Use a collector suitable for gold, such as xanthates, dithiophosphates, or specialized gold collectors.
كۆپۈرگۈچلەر: A low-to-moderate frothing agent like MIBC (methyl isobutyl carbinol) or polyglycol-based frothers can help stabilize bubbles without excessive froth formation.
Dispersants/Modifiers: Use dispersants to prevent slimes from coating the coarse gold particles and depressants to suppress gangue minerals.
5. Optimize Operating Parameters
كىرىش زەررىچە چوڭلۇقى: CPF works best for particles in the range of 150–850 µm. Adjust feed particle size within this range for maximum recovery.
Pulp Density: Maintain a slurry density of around 30–40% solids to balance flotation efficiency and transportability.
Qoladigan vaqt: Ensure sufficient residence time in the flotation cell to allow coarse particles to attach to bubbles.
Kabarcık oʻlchami: Use larger bubbles (100–300 µm) to enhance attachment of coarse particles.
6. Conduct Pilot Testing
Run pilot-scale CPF tests on the tailings to refine the parameters and evaluate recovery efficiency.
Assess the mass pull and concentrate grade to determine the economic feasibility of the process.
7. Concentrate Treatment
Further Processing: Depending on the concentrate grade, follow up with cyanidation, gravity separation, or other downstream processes to extract the gold.
چىقىندىلارنى باشقۇرۇش: Ensure responsible management of any new tailings generated during CPF.
8. Monitor and Optimize
Regular Sampling: Continuously monitor the feed, concentrate, and tailings for gold content to ensure optimal recovery.
جەرياننى كونترول قىلىش: Use advanced process control systems to dynamically adjust flotation parameters for variable feed characteristics.
Key Advantages of CPF for Gold Tailings
تەننەرخ ئۈنۈمى: Reduces grinding energy compared to fine particle flotation.
High Recovery: Captures coarse gold particles that are often missed by conventional methods.
مۇھىتقا پايدىلىق تەسىر: Reduces waste and improves tailings management.
By implementing this approach, you can effectively unlock the 8 g/t residual gold from tailings using coarse particle flotation.
