Using a feed hopper, ore is introduced into the head end of the Condor Dense Medium Separator with a small amount of the dense medium slurry. The slurry is made up of a suspension of ferrosilicon or magnetite in water and is introduced through the medium inlets at the bottom end of the separator, countercurrent to the ore feed.
Once broken into smaller pieces, the charcoal and iron ore (sand) are mixed together in a 1:1 ratio. 4. Charge the furnace. Before adding the iron ore and charcoal mixture, the furnace must be charged. Charging a furnace simply means heating it up to temperatures high enough for smelting to occur.

The ore may be easily beneficiated by a process know as wet-magnetic separation - this process has been employed for many decades in North America BIF with hematite as the dominant iron mineral may also be beneficiated through wet hydrometallurgical processes though it rarely is due to economic constraints Back to top South Australian iron ore …
Metals are taken from the rocks of an ore deposit using chemistry. In processing ore to recover the metal of interest, steps of the process can be divided into (a) the steps to prepare the metal for separation from the rest of the rock or other metals, and (b) steps to actually remove the metal from the rock and unusable or uninteresting parts

After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore. The beneficiation process should be as efficient and simple as possible, such as the …
copper processing Ores Britannica. Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a …
The Six Main Steps of Iron Ore Processing Multotec Canada. When the material exits the mill, the iron ore is classified using cyclones or vibrating screens that separate fine and large particles. The large particles are diverted back into the crusher and the fine particles will undergo a spiral gravity separation process. 5.
The extraction of metals and its isolation occurs over a few major steps: Concentration of Ore Extraction of metal from concentrated Ore Purification of the metal How is iron extracted from its ore? It's a long process which begins with Concentration through calcination roasting.
This drop in iron ore price is attributed to a cooling of the Chinese economy and an oversupply of iron ore from the major iron ore producers, The sizing separation of iron ore is achieved through the comminution and, In this chapter, the sintering process is first described and the key steps of the sintering process, namely, granulation ....
