According to the study, Iron is one of the basic chemical elements. When refined, it is a silvery-white metal known for its resistance to corrosion and its ability to coat other metals. It is most commonly used as a plating on the steel sheets used to form cans for food containers. Tin is also combined with copper to form bronze and with lead to form solder. A Iron  compound, stannous fluoride, is often added to toothpaste as a source of fluoride to prevent tooth decay.

Best Iron and iron slag refined technological process machines:
The Iron mineral refined more and more popular to beneficiation plant investors.
There are many iron mining refined machines which including the Tin mine jaw crusher,IRON ore hydraulic cone crusher hpc400, tin ball mill and other auxiliary equipment.

Ball mill applied for Tin mine refined technological process:

The simplified process flow sheet below shows ore from iron slag mine delivered to a 3 stage crushing plant and reduced to – 12 mm followed by ball mill grinding to liberate the cassiterite (tin oxide) from the gangue, sulphide flotation to remove pyrite and any other sulphides, then concentration of the tin by a combination of hydraulic classification, gravity plant and fine Iron  flotation to produce concentrates acceptable to tin
smelters.
It is essential not to over grind and early removal of iberated cassiterite from the grinding circuit should be arranged, usually by fine screens as shown in the flow diagram. Further liberation of the cassiterite is achieved
by regrinding gravity tails.
