Abstract

Abstract

To solve the problems such as uneven particle size distribution, low content of qualified particle size, high content of over-ground product in zinc regrinding stage, and low zinc recovery and so on, in second dressing plant of Chifeng NFC Baiyinnuoer Mining Co.Ltd. , the scheme of replacing steel ball with cylpeb in this operation was derived on the basis of studying the properties of feed, the semi-theoretical formula of ball diameter and the principle of accurate make-up ball, and the laboratory tests and industrial tests were carried out. The results showed that the average density, the average poisson ratio, the average elastic modulus and the average uniaxial compressive strength of ore were 3.51 g/cm³, 0.30, 15.30×10⁴ MPa, and 138.2 MPa, respectively. Meanwhile, cylpeb media as m (30×40)∶m (20×30)=50∶50 as the initial loading scheme of zinc regrinding mill according to the results deduced and the principle with the same mass was utilized. The results of the industrial tests showed that the -0.038 mm fraction yield of the overflow product was increased by 8.57 percent compared with the previous scheme and the overgrinding fraction yield was decreased by 2.01 percent, effectively reducing the phenomenon of overgrinding. In addition, the average recovery of zinc concentrate during the stable production period was 93.40% with a 1.46 percent higher than the previous scheme, and 508.08 tons of zinc metal would be expected to recover each year, generating 10.1616 million RMB for the beneficiation plant.
