| 中文摘要 | Studies on coupling process of sphalerite concentrate leaching in H2SO4-HNO3 and tetrachloroethylene extracting of sulfur were reported. Mechanism of coupling leaching and effects of adding amounts of C(2)l(4), temperature and liquid-to-solid ratio on leaching process were investigated separately. The results indicated that the zinc recovery was up to 99.6 % after 3 h of leaching at 85 degrees C, 0.1 MPa O-2, with 20 g sphalerite concentrate in 200 ml leaching solution of 2.0 mol/l H2SO4 and 0.2 mol/l HNO3, in the presence of 10ml C2O4. The leaching time was 50 % shorter than the common leaching. The coupling effect was distinct. (c) 2004 Elsevier Ltd. All rights reserved. |
| 英文摘要 | Coupling process of sphalerite concentrate leaching in H2SO4-HNO3 and tetrachloroethylene extracting of sulfur was investigated. Effects of leaching temperature, leaching time, mass ratio of liquid to solid and tetrachloroethylene addition on zinc leaching processes were examined separately. SEM images of sphalerite concentrate and residues were performed by using JEM-6700F field emission scanning electron microscope. The relationship between the number of recycling and extraction ratio of zinc was studied. The results indicate that 99.6% zinc is obtained after leaching for 3 h at 85 degreesC and pressure of 0.1 MPa O-2 with 20 g sphalerite concentrate in 200 mL leaching solution containing 2.0 mol/L H2SO4 and 0.2 mol/L HNO3, in the presence of 10 mL C2Cl4. The leaching time of zinc is 50% shorter than that in the common leaching. The coupling effect is distinct. The recycled C, Cl, exerts little influence on extraction ratio of zinc. |
