[ Instrument Network Instrument R & D ] Monoatomic MNC materials are considered to be the most promising non-noble metal ORR catalysts, and their active centers have been identified as metal-nitrogen coordination structures that mimic biological porphyrin centers. Previous research work has sh Continue Reading

[ Instrument Network Instrument R & D ] Recently, the Shenyang Institute of Automation, Chinese Academy of Sciences has innovatively proposed a method to remove false detection targets from aerial image detection results, and designed a corresponding detection network for aerial image characte Continue Reading

At present, China produced a weak magnetic field magnetic separator is widely used as a permanent magnet magnetic source. The magnetic poles used in the manufacture of magnetic separators are currently produced mainly in two materials. One is strontium ferrite, formula (SrO · nFe2O3), the other Continue Reading

The foaming agent is mostly heteropolar surface active substance, slightly soluble in water, and the composition is relatively stable. The following commonly used ones are as follows: 1) The foaming ability and characteristics of the second flotation oil (2# oil) are: foaming Stronger, can produce a Continue Reading

Ore grade level representative of how much metal content, high-grade ore beneficiation plant processing low-grade ore and the effect is not the same. When processing ore grades, it is necessary to obtain more concentrates under the same conditions than low-grade ores. At the same time, it can reduce Continue Reading

(1) Stage height - generally 40 to 60 meters. If the inclination of the ore body is different, different stage heights should be adopted. (Such as iron ore temple, the case of gently inclined ore body, a high stage is 30 to 45 m, when the inclination ore, stage 45 to 50 meters high. When Steep of 5 Continue Reading
