Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

Polymetallic weak magnetic iron ore refers to the phosphorous hematite, siderite. Most mineral processing plants adopt gravity separation – froth flotation – strong magnetic separation process or a combining process to the extraction of iron ore, and then use the flotation process to recover phosphorus or sulfide.

Conventionally iron and steel is produced by the reduction of high-grade iron ores in a blast furnace. About 80% of the world’s iron making is achieved through the blast furnace process and rest by different direct reduction (DR) processes. The role of high-quality iron ore and concentrate as a raw material is very critical to get the best quality iron and steel [1].

Besides, the separation machines are devide into the dry and wet magnetic separation. Generally, iron ore with an iron content of 35% can increase iron content by 20% after magnetic separation. Such a combined process method, the ore utilization rate can reach 90%. In the process of magnetic separation, it saves water, reduces cost and pollution.

The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).

Iron is the second most common element on earth and comprises nearly 5% of the earth’s crust. Iron ores are rocks and minerals that contain metallic iron that’s extracted by mining. Almost 100% of mined iron ore is used in steel production, making it essential for everything from staples to buildings.

When the iron ore is extracted from the mine, it must undergo several processing stages. Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing.
