Online Heat Pattern Estimation in a Shaft Furnace by ...

The state estimation technique based on the particle filter as outlined above was implemented in a ferro-coke furnace at JFE steel. Ferro-coke is a mixture of coal and iron ore with the ratio of 7 : 3 [8]. Owing to the catalytic effect of metallic Fe, the coke gasification reaction starts at lower temperature, compared with normal coke [9].

Equipment Selection for Surface Mining: A   Review

Equipment Selection for Surface Mining: A Review

2013-7-19 · A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
