SU1220688A1 - Method of dispersing solid materials in liquid - Google Patents

Description

f

The invention relates to the enrichment of minerals, primarily for dispersing a material in an aqueous environment by abrasion, and can be used for leaching, extraction and dissolution in the chemical, food and other industries.

The goal is to increase the efficiency of dispersion of clay impurities in the processing of potassium-containing ores and reduce energy consumption due to the selectivity of the process.

The drawing shows a diagram of the device for implementing the proposed method.

The device contains a reactor 1, throttling devices 2, made in the form of perforated grids, connected to sources of 3 oscillations, a booster 4 of consumption.

The method is carried out as follows. f

The material to be treated as a suspension is fed to the reactor 1 and is pumped through the throttling devices 2 using a flow rate booster 4. At the same time, oscillations are applied to the suspension, transmitted from vibrators 3 through throttling devices 2.

When the suspension passes through the orifices of the throttling devices, which oscillate due to repeated contact, the components of the solid material, which are prone to destruction by abrasion, are extensively dispersed.

The discharge from the orifices of the throttling jet fittings provides intense turbulent

mixing in the whole suspension volume and, as a result, uniform processing of the material.

After the processing of the suspension is completed, the separation of the toner-dispersed material and the material that is not subject to destruction is carried out in one of the known methods, for example, by decantation.

1JO Example. Silvinitrvu suspension with a particle size of 0.8-3.0 mm at, 6 for 60 s is treated in a saturated saline solution by repeated passage of throttling devices in the form of perforated grids through the holes, which are reciprocated oscillations with a frequency of 50 Hz and an amplitude of 20 mm 2 mm. The speed of the suspension through the holes of the gratings is maintained at 2.0 m / s.

The solid component in the solution consists of sylvite, halite, 25 halopelitic grains, their intergrowths and clay impurities.

During processing, clay impurities are 94% abraded. and slurry, while the 3Q component, i.e. sylvin dispersed 0.4%. Specific costs, due to selective dispersion, are 30–50 times less than by a known method.

Table 3 shows the dispersion data according to the proposed method.

A subsequent flotation of the solution obtained gives a flotation concentrate with a CS content of 95%, with its recovery of 90%;
