测定了半合成的不同成分的FeO-MgO-SiO2系炉渣粘度。在w(MgO)为6%~10%,w(Fe)/w(SiO2)为1.1~1.4,温度为1200~1500℃时,炉渣粘度随w(MgO)和w(Fe)/w(SiO2)的提高而增大;在w(MgO)<6%时,冶炼温度控制在1300℃即能保证顺利生产;当w(MgO)>10%时,镍冶炼炉渣的温度应控制在1360℃以上;在MgO含量较高时,可通过降低w(Fe)/w(SiO2)得到粘度较低的炉渣。金川闪速炉炉渣的合理w(Fe)/w(SiO2)为1.2左右。

By newly-developed computer model[1, 2] of the distribution behaviors of minor elements As, Sb, Bi and accessory elements Pb, Zn in copper flash smelting, copper flash smelting process of Guixi Smelter was simulated. Results showed that the predictions by the computer model were in agreement with the known commercial data from Guixi Smelter. Using Nagamorips physical suspension index equation[3], the apparent percentages of Cu and S in the slag were calculated, and the main form of mechanically entrained copper particles in the slag was determined to be sulfide. Furthermore, the effects of smelting temperature upon the fractional pressures, activity coefficients of As, Sb, Bi, Pb, Zn, etc. and their distributions in matte, slag and gaseous phase were analyzed. According to the simulations, when smelting temperature rises, the volatilizations of As, Sb, Bi, Pb and Zn in gaseous phase increase, while their distributions in matte decrease. The increase of smelting temperature is helpful to improve the total elimination rate of above-mentioned elements in gaseous and slag phases.

The main obstacle in directly reducing zinc sulfide concentrate in a commercial vertical retort is the difficulty to produce strong briquettes. The authors have successfully applied a new method to the preparation of strong briquettes which have satisfactory strength even after almost all the zinc sulfide in the concentrate has been reduced to zinc vapor. The method consists of mixing zinc sulfide concentrate with pulverized coal and calcium oxide, preheating and briquetting the mixture into a cylindrical briquette of 1.3cm in diameter, and then coking the briquette. Effects of mixing ratio, preheating temperature and time, particle sizes of concentrate, coal and calcium oxide on the strength of the briquette have been axamined. Sinze almost no sulfur has been observe to come out of the briquettes and also since they have considerably low specific resistance of 5.1Ω·cm, it has been suggested that the briquettes may be fed not only into a vertical retort but also into an electrothermic furnace without additional coke.
