Scientific and technological innovation, integrity and pragmatic, win-win development

Yuxi COSCO Mining Shaker Tailings have a volume of 500 tons/day, with a concentration of 13%, iron content of about 25%, fine particles below 325 mesh reach 80%, and ultra-fine slime below 1600 mesh accounts for 30% of the total tailings. A good index of concentrate iron grade 55.87% and recovery rate 60.88% can be obtained by using suspension vibration concentrator for one time separation. It can produce 33000 tons of refined iron powder every year, with an annual output value of more than 1400 million yuan.

Gejiu Xingxing Concentrator mainly deals with local tailings resources, with a daily processing capacity of 400 tons. The grade of such tailings is about 0.4, with -200 mesh accounting for more than 85% and metal content below 400 mesh accounting for more than 80%. The existing local technology has no recovery value. The suspended vibration separator was used to recover it, and since it was put into operation in June 2015, it has obtained good economic and technical indicators. The recovery rate of mineral processing is about 60%, and the annual output value exceeds 25 million yuan.

The tailings beneficiation process consisting of 68 suspended vibration cone concentrators has consumed less than 0.7 kW hours of electricity in actual production since it was put into operation. Compared with the traditional slime shaker, the processing capacity of the suspended vibration cone concentrator is 8-10 times that of the slime shaker, and the recovery rate of -19 micron (800 mesh) tin ore is more than 10% higher than that of the slime shaker. The cassiterite tailings concentrator with a daily processing capacity of 2500 tons obtains a good technical index of 3% tin concentrate grade and more than 70% recovery rate when the ore grade is 0.1~0.3, and the annual value of tin concentrate recovered exceeds 60 million yuan.

KGS II concentrator for tailings has a unique advantage, greatly reducing the equipment area, especially suitable for all kinds of tailings recovery

At present, a new process formed by a group of KGS-II concentrator and a suspended vibration concentrator is adopted to treat Inner Mongolia tungsten tailings and tungsten flotation tailings to recover fine cassiterite. Under the conditions of 0.2 ore feeding grade and 90% ore feeding particle size -200 mesh, according to the field application results, the daily output of concentrate contains more than 20% tin, with an output of 150-300kg and remarkable economic benefits. Based on the good recovery effect of "KGS II concentrator + suspension vibration concentrator" on the material, the user once again expanded the production application.

The scheelite tailings recovery system composed of 8 groups of "KGS-Ⅱ + suspended vibration" has been industrially applied in Inner Mongolia dressing plant. Under the condition that the feed grade is 0.1~0.2 and the feed grade is -200 mesh mineral accounts for 85%, the concentrate that can be produced every day contains 12.36 tungsten, and the output of each group is 100-150kg. The economic benefit is very obvious, and the floor space is small and the operation cost is low. Compared with the original traditional "shaker blanket" process, the recovery rate is more than 15%. The occupied area is only 1/3 of the original process, and the energy consumption is 1/2.

For the tailings of Panzhihua ilmenite tailings dressing plant, the fine ilmenite recovery system composed of "KGS-Ⅱ + suspension vibration" is fed after classification. Under the conditions of 6.39 ore feed grade and 90% ore feed particle size -200 mesh, 46.12 titanium iron concentrate can be produced with a recovery rate of more than 35%, providing a new way for clean recovery and utilization of fine ilmenite.
