metallurgical hydraulic washing of iron ore

Metallurgy: Terminology, processes used in extraction of

3/10/2020· Hydraulic Classifier Method: Hydraulic classifier consists of a tank having a hopper at the top and a pipe for carrying pressurized water. The ore is fed into the tank from the top, and the water is allowed with high pressure from the bottom of the tank. During this process the lighter impurities which are adhered to the ore float over the water which is removed by flowing water. The ore particles will

3/12/2020· This process is also called hydraulic washing. (ii) Froth floatation : Sulphide ores of copper, lead and zinc are generally concentrated by this method. The finely powdered ore is mixed with water and a small amount of oil in a tank. Air is blown into the mixture. A froth or scum is produced at the surface. The ore particles are carried by the froth to the surface. The earthy impurities sink

1.2.1 Gravity separation or Hydraulic wash In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water. Ore is crushed to a finely powdered form and treated with rapidly flowing current of water. During this process the lighter gangue

Almost all iron ore is used in blast furnaces to make pig iron, which is the main material for steelmaking. Small amounts of iron ore are used in other applications such as coal wash plants and cement manufacturing. Iron is the most used metal accounting for about 95% of total metal tonnages produced worldwide. Hematite is an iron oxide mineral. It is non-magnetic and has colour variations

The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day. This process of separating magnetic substances from the non-magnetic substances in a mixture with the help of a magnet is called magnetic

Metallurgical coal BHP

Metallurgical (met) coal (sometimes referred to as coking coal) is a naturally occurring sedimentary rock found within the Earth’s crust. Categories of met coal include hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverized coal for injection (PCI). These apply to the different quality grades of met coal, all of which are used to make steel. These categories refer to
