The effect of basicity and Foe on the meeting pot, viscosity and conductivity of Ca0-Si0-Al2 03-FeO slag was studied by high-temperature muffle furnace meting experiment for the characteristics of high silicon iron and aluminum in a waste circuit board mixture. The results showed that the meting point of slag decreased and then Increased, the increased and then decreased (1 300), and the electrical conductivity increased with the basicity increased from 0. 4 to 1. 8. And the meeting point of slag decreased and then increased, the decreased and the electrical conductivity increased with the Foe content increased from 15% to 30%. The suitable basicity and Foe content of this system stag was 0.8 - 1.4 and 16 % - 22%, respectively. Under the condition, the meeting point of slag was <1 220 [(hemispherical temperature), the viscosity of stag was <2 Pa s(1 300 ), and the copper yield was over 98. 0%. [ABSTRACT FROM AUTHOR] |
