2021-1-25 · The company held an EA authorising it to extract iron ore from a mine site in north Queensland. Between December 2017 and May 2018, the company conducted a ''trial'' involving dry magnetic separation of iron ore intended to achieve a higher iron percentage in the ore. This activity constituted ERA 31 - mineral processing.

Electromagnetic separation is used in the concentration ...

Hint: Electromagnetic separation is a technique used to extract metals from their ores. An ore is a substance that has a metal along with other elements or minerals. This technique involves the separation of the material that can be attracted to a magnetic field from the material that cannot be attracted to a magnetic field.

Dissolved iron in water--how to extract?

 · So, the iron won''t just sit there in the water, but will react with any dissolved oxygen and form oxide compounds. Can magnetism be used to extract the iron from the water Only a few metals are magnetic: iron, nickel, cobalt, and Gadolinium. Couldn''t a magnet be inserted into the solution and all the dissolved iron be attracted to it?
