Study on Size Distribution of Oolitic Hematite ...

the processing of oolitic hematite is considered to be one of difficult problems in mineral processing due to finely disseminated and complex structure of ore. The ore property, size distribution, mineralogy and mineral processing technology of refractory oolitic hematite in Longyan Iron Mine of Xuan Steel in Hebei, China is studied in the paper..

2019-8-1  The hematite and magnetite originated from Anshan ore deposit in Liaoning Province, China. Quartz was mined in Longyan in Fujian Province, China. High grade raw ores were carefully handpicked, crushed, ground and then purified on shaking table.

Dual Influence of Reduction Annealing on Diffused

2019-5-26  Band structure engineering of the interface between the semiconductor and the conductive substrate may profoundly influence charge separation and transport for photovoltaic and photoelectrochemical devices. In this work, we found that a reduction-annealing treatment resulted in a diffused junction through enhanced interdiffusion of hematite/FTO at the interface.
