Problems solved by technology

However, the raw materials of the above mineral processing methods are coarse concentrates enriched by primary ore rectorite, which do not involve associated minerals and gangue minerals embedded with oxidized ores with finer particle sizes, and do not involve the separation of minerals from raw ore to concentrate stages. , and the applicability of the method is poor, the product cost is high, the application range is limited, and it is difficult to realize large-scale mineral processing industrial production

Embodiment 1

[0121] A rectorite impurity removal and purification mineral processing process comprises the following steps:

[0122] (1) 800kg of primary ore containing 46.7% of rectorite is crushed to less than 10mm, and the tape is fed into a strong scrubbing machine with a liquid-solid ratio of 2.33:1, a stirring line speed of 9.2m / s, and a scrubbing time of 40min;

[0123] (2) Scrub and adjust the pulp until the liquid-solid ratio is 9:1, and enter the first stage high-frequency fine sieve. The coarse-grained pyrite and gangue minerals are separated on the sieve with a sieve size of 0.1mm. The underscreen material is adjusted to a liquid-solid ratio of 11.5:1 and enters the second high-frequency fine sieve with a sieve hole size of 0.044mm. Fine-grained pyrite and other associated minerals are separated on the sieve;

[0124] (3) After dehydration, the material under the sieve enters the impeller-type agitating mill for peeling and dissociation, the liquid-solid ratio is 3:1, the filli...

Embodiment 2

[0129] A rectorite impurity removal and purification mineral processing process comprises the following steps:

[0130] (1) 800 kg of oxidized ore containing 42% rectorite is crushed to less than 10 mm, and the tape is fed into a strong scrubbing machine with a liquid-solid ratio of 1.5:1, a stirring line speed of 10 m / s, and a scrubbing time of 60 minutes;

[0131] (2) Scrub and adjust the pulp until the liquid-solid ratio is 7.33:1 and enter the first-stage high-frequency fine sieve. The coarse-grained pyrite and gangue minerals are separated on the sieve with a sieve size of 0.15 mm. The underscreen material is adjusted to a liquid-solid ratio of 9:1 and enters the second high-frequency fine sieve with a sieve hole size of 0.044mm. Fine-grained pyrite and other associated minerals are separated on the sieve;

[0132] (3) After dehydration, the material under the sieve enters the impeller type agitating mill, grinds, grinds and dissociates, the liquid-solid ratio is 4:1, the...

[0137] A rectorite impurity removal and purification mineral processing process comprises the following steps:

[0138] (1) 800kg of oxidized ore containing 42% rectorite is crushed to less than 10mm, and the tape is fed into a strong scrubbing machine with a liquid-solid ratio of 1.5:1, a stirring linear speed of 12m / s, and a scrubbing time of 60min;

[0139] (2) Scrub and adjust the pulp until the liquid-solid ratio is 9:1, and enter the first stage high-frequency fine sieve. The coarse-grained pyrite and gangue minerals are separated on the sieve with a sieve size of 0.1mm. The underscreen material is adjusted to a liquid-solid ratio of 11.5:1 and enters the second high-frequency fine sieve with a sieve hole size of 0.044mm. Fine-grained pyrite and other associated minerals are separated on the sieve;

[0140] (3) After the material under the sieve is dehydrated, it enters the impeller type stirring grinding, grinding, grinding and dissociation, the liquid-solid ratio is 1....

Abstract

The invention discloses a rectorite impurity removal purification mineral separation process, a mineral separation system, a rectorite concentrate and an application of the rectorite concentrate, andrelates to the technical field of mineral separation. The rectorite impurity removal purification mineral separation process includes the steps: performing scrubbing dissociation and separation on crushed middle-low-grade primary or oxidation rectorite raw ores; performing stripping and grinding dissociation, mixing dispersion and roughing separation on dewatered separation materials; performing 1-4-section superfine grading and optionally high-gradient magnetic separation on roughing separation materials to obtain the rectorite concentrate. The rectorite impurity removal purification integrated industrial mineral separation method applicable to middle-low-grade primary or oxidation ores, a process method is economical and effective and can be flexibly adjusted and controlled according todifferent raw ore natures and different requirements for the rectorite concentrate, concentrates with multi-layer specifications and models are outputted on the same mineral separation production line, matched device parameters are suitably adjusted, requirements of process technical indexes can be met, and large-scale rectorite mineral separation industrial production can be easily achieved.

Description

technical field [0001] The present invention relates to the field of mineral processing technology, in particular, to a rectorite impurity removal and purification mineral processing process, a mineral processing system, rectorite concentrate and its application, in particular to different rectorite grades produced by different processes , impurity content rectorite concentrate and its application. Background technique [0002] Rectorite is a very rare regular interlayer clay mineral, which is composed of two dioctahedrons of mica layer and montmorillonite layer alternately stacked in a 1:1 regular manner. In addition to the common physical and chemical properties similar to other clays, rectorite also has the characteristics of good high temperature stability, large layer spacing, moderate negative charge on the surface and strong radiation resistance. And health and other fields have varying degrees of application advantages. [0003] The ore grade of rectorite is genera...
