· Increasing the percentage of metallic feed increases productivity in both vacuum levels; however, the productivity increase was more significant at high vacuum level. This is because high vacuum can bring more air flow per unit sinter raw mix; as a result, sintering speed is higher at higher vacuum conditions [ 4 ].

Granulation of sinter feeds is an indispensable step in the iron ore sintering process. Through granulating, iron ore fines, fluxes, fuels and recycle materials (e.g., return fines, dust, etc.) are made into granules that possess appro- priate moisture, reasonable size distribution and good bed permeability for sintering.

· Froth flotation has been widely used in upgrading iron ores. Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue minerals with depression of iron oxides. Nowadays, reverse flotation is the most commonly used route in iron ore flotation. This review is focused on the reverse

· The production of high-quality sinter is crucial for assuring consistent, stable furnace productivity with a low consumption of reductants. Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption.

· Iron ore is essential in steel making; however, high-grade ores have diminished, making low-grade ores inevitable. These low-grade iron ores need further beneficiation to upgrade the iron content. Currently, traditional physical and chemical methods are utilized and are not environmentally friendly. Bio-beneficiation techniques

The sinter structure and its characteristics mainly depend on the raw material chemistry, size, size distribution and the sintering process parameters. In sintering process heat is supplied by coke breeze in the sinter mix to raise the bed temperature to achieve partial fusion and diffusion bonding. Airflow rate and flame front speed in sintering process has

· The addition of concentrate and micropellets influenced the granule size distribution of the sinter mixtures. Their fractions in the sinter feeds varied from 10 to 40% (Table 1).The mass fraction of the − 0.25 mm size fraction significantly increased from 6 up to 23%, as the amount of concentrate increased.

· My Rowenta started leaking water everywhere, so I decided to satisfy my curiosity and buy the Silver Star ES-90 iron from Wawak. For $99, I figured it worth a try. So why a gravity-feed iron? I heard gravity-feed irons don’t tend to leak like other irons, and that they last longer. Also, the water reservoir allows for longer periods of
