01 Gravity separation process. The gravity separation is to extract the iron from limonite based on gravity. As the main process used in the extraction of iron from limonite, the gravity separation process is often used to deal with coarse grain ore in most cases. In order to further improve the concentrate quality, most limonite concentrators

Concentration and Recovery Formulas. These are used to compute the production of concentrate in a mill or in a particular circuit. The formulas are based on assays of samples, and the results of the calculations are generally accurate— as accurate as the sampling, assaying, and crude ore (or other) tonnage on which they depend.

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.

This is one of the mineral concentration processes. In this process, a mineral which is mag-netically susceptible is extracted from a nonmagnetic mixture or a less magnetic mixture of minerals using magnetic force. Magnetic separation can be useful especially in mining iron as it is separated by a magnet. (Mineral Technologies, 2016)
