How to judge the difficulty of re-election of two minerals?

Re-election is based on the mineral density of the mineral separation, re-election must be carried out in the medium. Therefore, the density of minerals and the density of the medium are the most important factors affecting the re-election process. The difficulty of re-sorting two minerals can be roughly judged by the following formula:

In the formula, δ 1 , δ 2 , ρ— the density of light minerals, heavy minerals and medium, respectively.

E is called the reselection criterion for judging. The larger the E value, the easier it is to separate. It is customary to divide the E value into several levels as shown in Table 25 .

Table 25 judges the difficulty of re-election separation based on E value

To separate the metal and non-metallic minerals, for example, is generally greater than the density of metallic minerals 4.6g /cm 3 , the density of non-metallic minerals is generally less than 2.8 g /cm 3 when in the water medium (ρ= 1.0 g When separating them in /cm 3 ) , then:

It is easy to separate.

It can be seen from the above formula that for two specific minerals, that is, δ 2 and δ 1 are constant, the larger the density ρ of the medium, the larger the E value, and the easier the separation becomes. For example, when ρ= 1.8 g /cm 3 , separating metal and non-metallic minerals, then

Separation is extremely easy at this time.

Of course, the particle size, shape, and motion state of the mineral particles are also important factors in the re-election process. Therefore, it is only preliminary and rough to judge the difficulty of re-separation by using the E value as the criterion.
