Process Description

Introduction: Coarse concentrate regrinding and re-separating improves the concentrate index; Determine concentrate regrinding and re-separating process according to the ore properties; To reduce energy consumption by 30%, recovery rate is increased by more than 10%.

Application: Molybdenum dressing production line can be used for single or refractory molybdenum with complex properties, close sulfide minerals symbiosis and fine particle distribution

  • Staged Grinding and Sequential Separation

  • This approach begins with mixed roughing after coarse grinding. The coarse concentrate is then reground and subjected to cleaning stages. The key advantage is that only a small portion of the total ore feed requires regrinding. This promotes the effective liberation of molybdenum minerals while significantly reducing energy consumption, ultimately yielding a high-grade concentrate and a high overall recovery rate.

  • Enhanced Flotation for Higher Concentrate Grade

  • The grade of the final molybdenum concentrate is elevated by strengthening the flotation process. This involves:

    Precise Reagent Control: Strictly managing the reagent system during the roughing stage to minimize metal loss across multiple cycles.

    Bubble Enrichment: Leveraging the natural cleaning effect of bubbles to achieve dual enrichment.

    Froth Washing: Implementing concentrate foam washing to remove entrained impurities and further enhance product purity.

  • Stage-Processing to Maximize Recovery

  • A stage-processing technique is employed to capture valuable minerals across a wide range of particle sizes. By tailoring the recovery process to different size fractions, this method ensures that the maximum amount of molybdenum is recovered, thereby guaranteeing a high overall recovery rate.

  • Integrated Process and Equipment Design

  • The success of the flotation line relies on the seamless integration of technology and machinery. Shunzhi provides a complete set of compatible equipment for the entire production line. This integrated approach ensures perfect synergy between the processing technology and the equipment, guaranteeing stable operation and peak performance.

Processing Flow

  • Crushing and Grinding: After crushing molybdenum ore, grind it into pulp with ball mills to achieve monomer dissociation of molybdenum minerals such as molybdenite.

  • Roughing: Add collectors such as kerosene and diesel oil and frothers to the pulp, and obtain molybdenum rough concentrate by flotation.

  • Cleaning: Conduct multiple cleanings (usually 6-8 times) on molybdenum rough concentrate, and remove impurities such as copper and iron by adding depressants to upgrade molybdenum grade.

  • Scavenging: Scavenge the roughing tailings to recover residual molybdenum minerals and improve resource utilization rate.

  • Thickening and Dewatering: Concentrate the cleaned molybdenum concentrate with thickeners and dewater it with filters to obtain molybdenum concentrate filter cake.

  • Drying and Packaging: Dry the filter cake with dryers and conduct metering and packaging to obtain finished molybdenum concentrate.

  • Tailings Disposal: Treat tailings environmentally and then stockpile them, or recover associated minerals from them.
