Enrichment laboratory

Department of Precambrian Geology and Geodynamics

The laboratory is engaged in the grinding of rocks and the selection of monofractions of accessory and rock-forming minerals.

 

Crushing of rocks

At the first stage, the rock is crushed and crushed. The first stage of crushing (maximum size of 80 mm) is carried out in a jaw crusher with an intake opening of 150x180 mm to a size of 40 mm; the second stage - in a crusher with a receiving hole of 100x60 mm to a coarseness of -10 mm. Next, crushing to the required size (-0.65 mm) is carried out in several steps on a DV-200x125 roller crusher.

Fine grinding of samples from 0.2 - 0.3 mm to - 0.074 mm is carried out in a vibrating grinder.

Separation of the rock into a sieve and a concentrate of light minerals is carried out on a KS-0.5 L concentration table.

An electromagnetic separator 138T is used to separate the concentrate into monomineral fractions.

 

Equipment:

1. Jaw crusher for coarse crushing:

-   size of rock fragments for crushing – 80-100 mm;

-   size after crushing – 50-60 mm.

 

2. Jaw crusher of medium crushing:

-   size of rock fragments for crushing – 50-60 mm;

-   size after crushing – 25-30 mm.

 

3. Jaw crusher for shallow crushing FRITSCH-100:

-   size of rock fragments for crushing – 25-30 mm;

-   size after crushing – 10 mm.

 

4. Roll crusher:

-   size of rock fragments for crushing – 10 mm;

-   size after crushing – 3 – 5 mm.

 

5. Roll crusher for shallow crushing:

-   size of rock fragments for crushing – 3-5 mm;

-   size after crushing – 0.65 mm.
