Study on Re-separation Process of Middling Coking Coal

摘要：

High quality coking coal is a major steelmaking and metallurgy ingredient, but the coking coal resource is tightly supplied worldwide.There will be important realistic significance that how to achieve the maximum recovery of low ash, high quality coking coal from the limited middling coking coal products. Aiming at middling coking coal product with the ash content of 56.50％ , the tests of grinding and flotation is carried out in this paper so that the optimal grinding size, spieces and dosages of the flotation reagent and the other technological conditions can be gained.The result shows that it is a effective process for fine - grained dissemination of fine coal to, achieve the re - separation of middling coking coal so as to reduce ash content of cleaned coal and improve the yield of cleaned coal.
