The proposed approach could be an effective way to distinguish between mineral and equipment limitations and, on account of this, be a selective descriptor of the separation efficiency (Spottiswood and Kelly, 2001). Furthermore, the comparison between those curves and the Ideal Upgrading curve is an indicator of the ore liberation degree.
As will also be seen, any increase in the number of separations and mineral components to be accounted for, greatly increases the complexity of the computations. Two Product Formula Online Calculator <– Click to Use Applicable to the simplest separation where only one concentrate and one tailing result from a given ore feed.

Methods based on recovery of minerals are better than the other available methods. Among the recovery-based methods, those proposed by Lincoin and Gaudin probably addressed most of the important aspects of efficiency calculation. However, in these two methods, the separation efficiency value is also a function of feed characteristics.
Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of …
MODELLING OF SEPARATION CIRCUITS USING NUMERICAL ANALYSIS 3 well known of these in the mineral sands industry is the theory that Holland-Batt1 developed. These methods are not necessarily intuitive and do not have the capacity to model any separation curve shape or form, for example S-shaped curves. It was the aim of the author to derive an ...
Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.

separation at different magnetic fields and show that the advantage of higher magnetic field in separation efficiency decreases with the increase of saturation magnetization of magnetic mineral. Index Terms—High gradient magnetic separation, mineral processing, particle capture, intergrowths, magnetic field, laminar flow.
The high frequency vibrating screens will often be used as a secondary screener as its purpose is to separate the finer minerals. This not only ensures good separation efficiency, it will also help to maintain the life-time of the screen. Blinding can occur significantly if particle sizes are not within the screens' designed criteria.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
