| Abstract: | Super - fine Fe304 powders were synthesized by using Pyrite Cinder as feed material via magnetic separation and maturing and purgation technology. The method consists of pyrite cinder matured temperature and time, synthesized temperature, finally obtained super -fine Fe304 powders. Experimental results showed that the particle size of Fe304 powder is sub - micron level and the purity of Fe304 come up to 99. 5%. The scientific experiments can provid a nem path for utilizating of pyrite cinder. |
