BAIHUALING beneficiation plant is one of the two concentrator Jinduicheng Molybdenum Group Co., Ltd. subsidiary, located in the Wen River bath, yard, imposing, responsible for more than two-thirds of Molybdenum Company primary products The production task is the No. 1 and the world's fourth largest molybdenum concentrator in Asia.
The plant was completed and put into operation in November 1983 , and the mine was transported by electric motor vehicle. At present, the scale of the ore dressing plant reaches 7.2 million tons of ore per year, the grade is over 52% , and the sulfur concentrate is 240,000 tons / year. The tailings are sent to the plant by the five-stage pumping station. 8 km The Lixi tailings mine has a tailings pond area of 10 square kilometers and a storage capacity of 165 million cubic meters. The factory covers an area of 18. 60,000 square meters The main production plant construction area 6. 50,000 square meters There are crushing workshop, grinding and floating workshop, sulfur selection workshop, finished product workshop, tailings workshop, electromechanical workshop, iron selection workshop and fifteen departments. The products include molybdenum concentrate, sulfur concentrate and iron concentrate.
Baihualing Concentrator has 111 technical cadres, accounting for 86.7% of the total number of cadres; there are 4 senior engineers. There are 10 technicians and 40 senior workers in the workers' ranks. The management cadres have basically achieved youthfulness and specialization. The overall quality of the staff has been continuously improved, forming a team of cadres and workers who dare to fight hard, and who are adept at advancing and a team of skilled and competent engineers and technicians.
Baihualing Concentrator adopts the " three-stage and one-closed " crushing process, ore granularity 15mm More than 88% ; grinding flotation process using " segment grinding - phase selection " , preferential selection of molybdenum, coarse tail sulfur, sulfur tail iron, fine tail copper , useful minerals have been comprehensively recovered; molybdenum After concentration, filtration and drying, the ore is dehydrated to obtain molybdenum concentrate with a grade of 52% and a water content of less than 8% . The tailings are sent to the tailings pond for deposition and storage. Due to the continuous optimization of the process and the continuous improvement of management level, in 2001 , the treated mineral volume reached 7.715 million tons, the super capacity was 47.78% ; the production standard of molybdenum concentrate was 21492 tons, and the total productivity was 7.4 times higher than the initial stage of construction. The grade of minerals is 52.75% , and the product quality has reached the world advanced level.
Long process route, heavy equipment and many types of equipment are the main features of Baihualing Concentrator. Up to now, the whole factory has 38 sets of Class A equipment, and the number of various types of equipment has reached 1,540 sets, including 741 sets of mechanical equipment, 755 sets of electrical equipment, 44 sets of storage equipment, and various types of pipelines. 12,000 meters . Crushing system mainly equipment PX1200 / 180, PXZ1200 / 160 gyratory crusher each 1, PYB2200 standard cone crusher three, PYD2200 short head cone crusher six; grinding system mainly equipment MQG φ 3600 × 4000 ball mill 9 Taiwan, MQY φ 3600 × 6000 overflow ball mill 1 set, the main equipment of flotation system is KYF/XCF -24m3 There are 71 flotation machines. Due to years of technological transformation, the total equipment of Baihua Concentrator has reached the leading level in the domestic industry, and the automation process has been greatly improved, realizing the automatic control of the dosing system and the grinding system. The operating rate of equipment has reached more than 96% since 2000 , and it is close to the international leading level.
Over the years, Baihualing Concentrator has adhered to the road of innovation and development, completed a number of process and equipment transformation projects, optimized the production process, stabilized the equipment foundation, and created the first domestic non-cyanide molybdenum. Grinding -- the application of grading automatic control technology is becoming more and more mature, and the selection system transformation is fruitful.
