Remarkable Reduction

In this work, a new desulfurization process of high sulfur coal was designed and examined. The novel process involved pyrolysis of high sulfur coal at low temperature and then a dry magnetic separation. For testing the cleaning coal process, a Chinese high sulfur coal, Baisu coal was pyrolyzed in a fixed bed reactor from 400 to 700°C for 30min, and then separated by a dry magnetic separator. The results showed that under optimum conditions, a remarkable reduction of sulfur content in coal was achieved, and more importantly, almost all pyrite sulfur in coal was removed.

Gravity Concentration

The main elements can be recovered for mineral processing in a mineral containing titanium of Baoding area were Ti, Fe and V, and the elements in the main gangue minerals were Si and Al. Gravity concentration, gravity concentration-high intensity magnetic separation and gravity concentration-flotation tests were performed on the ore sample respectively. The results showed that, in the test of shaking table, when the grinding fineness was -0.074mm 93%, the productivity of concentrate can reach 32.24%; when grinding fineness was -0.074mm 93%, after gravity concentration-magnetic separation, 30.25% of concentrate productivity can be attained; when the grinding fineness was -0.074mm 85%, after gravity concentration-flotation, the productivity of concentrate was 3.31%. Maybe it's the condition of the tests wasn't controlled well, especially adjusting pH value in the flotation stage, it's hard to control, so the results were not very good.
