A molybdenum mine in Bulgaria, the metal minerals in the ore are mainly pyrite and molybdenite, and the vein minerals are mainly quartz, the nature of the ore is relatively homogeneous, with little change in grade, and the Kemble grain size is medium-fine. Industrial ore body molybdenum grade between 0.06-0.11%, the original scale of the processing plant 1000t / d, beneficiation and crushing process for the two stages of a closed circuit, grinding for the stage of grinding, stage separation, concentrate grade of 42-45%, recovery rate of 82%.

In order to comprehensively utilize the resources and increase the development efforts, it was decided to expand the original processing plant, the scale of which was expanded from 1000t/d to 10000t/d, and the plant entrusted Chunlei to do the technical transformation. Chunlei, through many repeated tests and communication with customers, finally made the technical indicators exceed the expected results.

Considering the reliability of the process, the main contents of Chunlei’s ore modification for this ore body are as follows: cancel the second section of ball mill and classification operation; cancel all the flotation operation after the second section of milling; and change the roughing selection to the four-stage selection, which results in a molybdenum concentrate with a grade of 45.55% and a recovery rate of 90.26%.

Through the experimental research and transformation of the processing plant, adopting the new pharmaceutical system, without changing the original technical indexes, the plant reduces the second grinding and subsequent molybdenum ore flotation equipment, shortens the process flow, saves the cost of power, steel balls, pharmaceuticals, personnel and management costs, and saves more than 10 million yuan per year, which has been highly praised by the cooperative parties, and long-term cooperation has been established.

Introduction to Magnetite

Molybdenite refers to ores or minerals containing the element molybdenum, which is a transitional ferrophilic element that can form a variety of compounds with a variety of elements, such as molybdate and thiomolybdate. The common ones are pyromolybdenite, molybdenum pyrite and molybdenum sand. Among them, pyromolybdenite is the most common molybdenum ore with high molybdenum content, and its main composition is MoS₂.

Introduction To The Process Of Magnetite Ore Magnetic Separation Process Production Line

• Stage grinding to improve concentrate index: Mixed roughing is carried out in the case of rough grinding, and the selected rough concentrate is regrinded for further concentration. The rough concentrate after concentration has less ore volume and can realize the dissociation of minerals, which saves energy while obtaining a high grade and high recovery concentrate.
• Strengthening the flotation process to improve the molybdenum concentrate grade: Strictly control the dosage of chemicals in the roughing stage, so as to “collect as early as possible” and reduce multiple cycles and useless loss; make full use of the secondary enrichment effect of the foam, and reduce the impurities in the foam by appropriately adding water and flushing the concentrate foam, so as to achieve the purpose of strengthening the flotation.
• Stage sorting to ensure the recovery rate: Adopting stage sorting to recover useful minerals of different grain sizes as much as possible and improve the index of concentrate.
• Combination of process equipment: Chunlei Machinery configures supporting equipment for the whole set of production line to ensure that the equipment fits the process demand.
