Silicon is a typical impurity in iron ore. Because the silicon content of steel is too high (more than 0.5%), its elongation, shrinkage, and impact toughness will be significantly reduced. Therefore, ferrosilicon beneficiation to reduce its gangue mineral content and increase its iron content before it can be used as raw material for blast …
The extraction of iron ore typically involves a combination of various types of equipment. Some of the equipment that may be used in the extraction process includes: 1.
The blast furnace is the first step in producing steel from iron oxides. The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to …
The partially reduced ore is then smelted in the second unit, and liquid iron is produced. Smelting-reduction technology enables a wide range of coals to be used for iron making. Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast ...

Gravity Separation Spirals are the most practical equipment to use for gravity separation of iron ores because of the high throughputs needed. SGS has a variety of spiral test rigs, including the spiral designs typically used in iron ore plants. Our accessory equipment allows sizing of feeds, multiple spiral stages, and recycling of products.
The first step in this process is crushing and grinding the ore to a fine powder. This powdered ore is then subjected to a process called magnetic separation, where magnets are used to separate the iron particles from other minerals present in the ore. This helps in purifying the iron ore and increasing its iron content.
Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher ...
