tite expected from the CIPW norm, probably due to loss of zircon + apatite as inclusions in other minerals. In thin section, ~25% of zircons were inclusions in magnetic minerals, and therefore would be lost during magnetic separation.

At Kovdorsky Mining-and-Processing Integrated Works apatite is floated from tailings of magnetic separation while dressing complex brazilite–apatite–magnetite ore. In this process saponified tall oil fatty acids added with oxyethylated alkyl phenols—Neonol AF 9-10 and Kemir М-246—are used as collectors.

High gradient magnetic separators Continuous HGMS

• Apatite upgrading • Sulphide ore recovery and separation The success of any magnetic separation process is governed by the property of the material to be collected and the structure of the separator to carry out the process. This can be expressed in the relationship between on one side the competing forces and the magnetic force on the other.
