Problems solved by technology

In the prior art, microbial treatment can only remove iron minerals, but cannot remove the composite titanium oxides in iron minerals, and the efficiency of microbial iron removal is low. Therefore, the applicant aims at the characteristics of impurities in albite in Hezhou City, Guangxi, to simultaneously remove For the purpose of removing iron and titanium impurities, and improving the efficiency of iron removal, optimize and improve the selection of strains and the method of use
[0004] The content of mica in mineral rocks is low, but it has a great influence on the whiteness and quality of feldspar ore, and mica is a silicate mineral with layered structure, acid and alkali resistance, stable chemical properties, and difficult to be removed
At present, mica removal methods are mainly as follows: under certain conditions, mineral dressing agents are used to capture mica and separate it from feldspar. Commonly used floating agents are chemical agents such as surfactants and ionic collectors. Most of the agents are Toxic substance, large amount of use and discharge will pollute the environment
For example, Chinese patent 201710843849.9 discloses a production and preparation method of albite powder, which removes impurities through a series of physical meth

Embodiment 1

[0021] In this embodiment, a method for beneficiating albite feldspar includes raw ore cleaning, screening, crushing, grinding, microbial treatment, flotation and dehydration. The microbial treatment is: dehydrating the 200-mesh fine sand obtained by grinding to After the water volume is 15%, add the bacterial solution to soak for 15 hours, the solid-to-liquid ratio is 1:100, filter after soaking, take the solid matter, rinse it with clean water, dehydrate until the water content is 25%, and obtain the deferro-titanium ore; The bacterial liquid is a mixture of Brevibacterium flavum bacterial agent and Bacillus licheniformis bacterial agent, and the weight ratio is 1:5;

[0022] The flotation is as follows: adding water to the deferro-titanium ore sand to adjust the concentration to 35% pulp, and adjusting the pH of the pulp to 1, adding medicaments with a mass of 3% of the pulp, stirring until foaming, scraping off the foam, It is dehydrated to a water content of 15%, and it i...

Embodiment 2

[0029] In this embodiment, a method for beneficiating albite feldspar includes raw ore cleaning, screening, crushing, grinding, microbial treatment, flotation and dehydration. The microbial treatment is: dehydrating the 250-mesh fine sand obtained by grinding to After the water volume is 12%, add the bacterial solution to soak for 20 hours, the solid-to-liquid ratio is 1:150, filter after soaking, take the solid matter, rinse it with clean water, dehydrate until the water content is 20%, and obtain the deferro-titanium ore; The bacterial liquid is a mixture of Brevibacterium flavum bacterial agent and Bacillus licheniformis bacterial agent, and the weight ratio is 1:10;

[0030] The flotation is as follows: adding water to the deferro-titanium ore sand to adjust the concentration to 45% pulp, and adjusting the pH of the pulp to 2, adding medicaments with a mass of 5% of the pulp, stirring until foaming, scraping off the foam, It is dehydrated to a water content of 12%, and it ...

Embodiment 3

[0037] In this embodiment, a method for beneficiating albite feldspar includes raw ore cleaning, screening, crushing, grinding, microbial treatment, flotation, and dehydration. The microbial treatment is: dehydrating the 300-mesh fine sand obtained by grinding to After the water volume is 150%, add the bacterial solution to soak for 18 hours, the solid-to-liquid ratio is 1:120, filter after soaking, take the solid matter, rinse it with clean water, dehydrate until the water content is 22%, and obtain deferro-titanium ore; The bacterial liquid is a mixture of Brevibacterium flavum bacterial agent and Bacillus licheniformis bacterial agent, and the weight ratio is 1:7;

[0038] The flotation is as follows: adding water to the deferro-titanium ore sand to adjust the concentration to 40% pulp, and adjusting the pH of the pulp to 1.5, then adding a medicament with a mass of 4% of the pulp, stirring until foaming, scraping off the foam, It is dehydrated to a water content of 13%, an...

Abstract

The invention discloses an albite concentration method, and relates to the technical field of albite processing. The method comprises the following steps of raw ore cleaning, screening, smashing, oregrinding, micro-organism processing, flotation and dewatering. The micro-organisms are brevibacterium flavum and bacillus licheniformis. In the floating step, water is added into ore sand after deironing to produce ore pulp with concentration of 35-45%, the pH of the ore pulp is adjusted to be 1-2, an agentia of 3-5% is added for stirring until bubbling appears, foam is scraped out, and dewateringis conducted until water content is no more than 15%. The agentia comprises an aloe extract, an eucalyptus leaf extract, citric acid and an N-dialkyl double quaternary ammonium salt. Iron titanium impurities and black mica in the albite can be effectively removed, and magnesium oxide can be further removed. Albite powder with high whiteness, low iron, low titanium, low mica and high quality can be produced. The adopted floating agentia is environmentally friendly, and is non-toxic and pollution-free. The whiteness of the obtained albite powder is more than 61, and the method is better than atraditional method.

Description

【Technical field】 [0001] The invention relates to the technical field of albite processing, in particular to a method for refining albite. 【Background technique】 [0002] Sodium feldspar is a kind of feldspar, which is a common feldspar mineral and is a sodium aluminosilicate. Albite is generally a glassy crystal, and it is one of the main raw materials for making glass and ceramics. In recent years, with the rapid development of my country's ceramic industry and glass industry, the demand for high-purity albite continues to increase. Iron minerals, titanium oxides, mica, and quartz are the main impurities of albite ore. Among them, iron minerals are mainly magnetite, limonite and hematite, and mica is mainly muscovite and biotite, which affect the quality of ceramics. Whiteness, dielectric properties, chemical stability, etc. [0003] At present, the iron removal methods of feldspar are mainly magnetic separation, acid leaching and flotation. Magnetic separation has high...
