Held recently in Zhengzhou "conservation and comprehensive utilization of mineral resources survey project" the progress and achievements Zhanping said, made a number of breakthroughs in difficult to use complex non-ferrous metal ore and iron ore difficult to use "drop upgrading miscellaneous" and so on.

For refractory tungsten and molybdenum ore, low grade copper-nickel ore, lead, zinc, iron and copper were associated ore, refractory Cu polymetallic mineral resources, the research team developed a new and efficient utilization of technology and pharmaceutical processing, Henan Long Ping Molybdenum Tungsten Mine The lead-zinc mine in western Henan has determined a reasonable process. In Gansu rubidium multi-metal mining, developed a new type of flotation reagent, thereby leveraging the rubidium polymetallic ores.

Difficult to use the iron ore "quality improvement and impurity reduction" technology, in the typical sedimentary type of red iron iron ore in Wushan and Lancang, developed a "suspension roasting-magnetic separation (Fession Roasting-Magnetic Selection) which is suitable for the characteristics of sedimentary complex refractory iron ore resources in the eastern part of Fujian Province. - Reverse flotation) "New processes, new equipment and new pharmaceuticals can revitalize hundreds of millions of tons of red limonite and siderite resources. Xinjiang West Kunlun Iron Mine uses magnetic field screening method to prepare high-purity iron concentrate process test to obtain excellent index of concentrate yield (for raw ore) 20.30%, magnetic iron grade 71.17%, and total iron grade 71.56%. The reduced iron powder was prepared by reduction roasting of high-purity iron concentrate, and a calcined sample of 95.13% of total iron and 96.36% of metallization was obtained.

Sichuan refractory glue for phosphorus ore, fluorite Chongqing region - barite ore, kyanite mine in Gansu large complex and difficult to use dolomitic clay mine, difficult to use in low-grade talc and other typical non-metallic ore utilization technology research And made a breakthrough. In addition, in the tailings, tailings investigation and resource technology, 313 tailings ponds were investigated, sampled, analyzed and tested. It was found that 13 medium-sized ore tailings contained higher content than industrial grade or comprehensive utilization. The valuable element of taste.
