Study on the new technology of separation of polymetallic ore

Utilization of Mineral Resources, Institute of Chinese Academy of Geological Sciences, respectively Lara copper-molybdenum multi-metal ore, antimony ore and copper luhuo gully on behalf of low-grade copper oxide ore carried out research polymetallic ore separation technology. The Lala copper-molybdenum polymetallic ore was finally determined to adopt the copper-molybdenum mixed flotation- cobalt - iron -copper-molybdenum separation process, and the expansion test was carried out. The technical indicators obtained were: copper concentrate grade 20.57%, recovery rate 92.21 %; molybdenum concentrate grade 47.75%, recovery rate 53.26%; iron concentrate grade 62.85%, recovery rate 20.47%; cobalt concentrate grade 0.33%, recovery rate 21.90%. The copper-molybdenum separation uses EM-hour 08-2 copper inhibitor. The agent has good copper-inhibiting effect in copper-molybdenum separation, long acting time, low dosage, non-toxic, biodegradable, no pollution to the environment, and is a kind of copper inhibitor. Environmentally friendly pharmaceuticals.

The furnace copper copper polymetallic ore uses the flotation process of copper and copper, and obtains copper concentrate with a grade of 21.26% and a recovery rate of 77.34%, and a concentrate with a grade of 45.95% and a recovery rate of 70.02%. The low-grade copper oxide ore in the Shishigou, Panxi, is enhanced by ammonia leaching. The copper leaching rate is 69.72%. The recovery rate of ammonia is 82% when the volatile ammonia is not recovered. The copper extractant N902 is used for two-stage extraction and three extractions. In the stage back extraction test, the copper extraction rate is greater than 99%, and the stripping rate is greater than 97%. The copper electrowinning of the extraction enrichment liquid can obtain high purity cathode copper in accordance with the national standard GB/ton 467-1997. The leaching uses a rough selection, a second sweep, and three/four selections to obtain a copper concentrate with a yield of 0.74%, a grade of 23.11%, and a ore recovery of 11.29%.

- disseminated copper-molybdenum polymetallic preliminary technical and economic analysis Panxi shows that the construction of a annual processing 450,000 tons of ore beneficiation plant, which can produce 12,900 tons of copper concentrate per year, 180 tons of molybdenum concentrate, 2400 tons The cobalt concentrate and 177,000 tons of iron concentrate have an annual sales income of 142.09 million yuan and a profit of 74.512 million yuan.

The preliminary technical and economic analysis of low-grade copper oxide ore shows that the copper smelter with the annual output of 5,000 tons of cathode copper of the same type of low-grade copper mine is constructed by this process, with an annual profit of 43.359 million yuan, with remarkable economic benefits.

This research technology is expected to make effective use of copper polymetallic refractory resources with a reserve of more than 12 million tons of copper polymetallic ore mines in Sichuan Huili and Tibet Saoda.
