Process Mineralogy Analysis of Jinchuan Nickel Slag
-
Abstract
By means of chemical composition analysis,XRD,optical microscope,SEM-EDS and other measurements,the process mineralogy of Jinchuan nickel slag are studied,include grain-size composition,grindability,chemical composition,mineral composition,structure,the metals distribution of Fe Ni Cu.The result shows that the particle size of the slag have focused on 1 to 5 mm,the relative grindability coefficient of the slag K =0.31,that make it less grindable than the pyrite.Iron oxide,silica oxide,magnesium and calcium oxides are the main components of the slag,the other substances are little,the slag belong to alkali.Compared with other nickel slag,it has relatively low iron,higher magnesium,and there is much more nickel lost.The phase composition of the slag include forsterite and glass,a few Cu-Ni sulphide,chalcocite and magnetite...etc.Most forsterite present as styloid and arranged along a certain direction,the other forsterite present irregular shapes,the glass filled in it.The main structure of the slag is solid rong body separation.The fine metal sulfide particles distribute in silicate irregularly,the liberation degree of the valuable mineral is difficult.The irons are mainly located in the forsterite,nickel and copper are mainly located in the cu-ni sulphide. -
