In this study, the main aim was to recovery the gold from iron tailings, and comprehensive recovery of iron by using combined separating technology. Experimental studies were carried out on the iron tailings in Dahongshan samples, which contain 0.5g/t of gold and 16.8% of iron. Through the experiment, the first is pre-discarding tailings by centrifuge, and then the gold is recovered by cyanidation leaching with using of H2O2 to increase the rate of gold dissolution. The gold’s leaching rate can reach 97.60%. The qualified iron concentrate can be got from leaching slag and gravity tailings by magnetic separation. Iron tailings get a comprehensive utilization, which has a better effect.

The extraction of vanadium and chromium from high chromium content vanadium slag by salt roasting and water leaching process has been investigated, which uses mixed sodium salts (Na2CO3 and NaOH) as additive agent in roasting process. The mineralogical morphology was prospected by TG-DSC, XRD, SEM and EDS. The oxidation of slag and transversion of V/Cr-containing phase and sodium salts have been discussed. It has been demonstrated that the presence of NaOH contributes to decompose spinel and olivine phases, which is beneficial to reduce the roasting temperature and elevate V, Cr leaching ratio. The roasting parameters have been studied as a function of roasting temperature, roasting time and ratio of alkali, in which the roasting temperature is the most effective factor on the leaching rate of vanadium and chromium. Under the optimum condition, the leaching rates of V and Cr reached 95.8% and 97.6%, respectively.

The properties of the flue dust of an iron-making plant and the results of separation experiment were given. The test results show that the flue dust could be enriched by gravity-flotation-magnetic separation technology to produce carbon concentrate and iron concentration. The results showed that 56% iron concentrate and 65% carbon concentrate could be got.
