Description
Technical Field
The invention relates to a barite purifying and whitening agent and a purifying and whitening method thereof, belonging to the field of barite production.
Background
Barite is an important barium-containing mineral and has the characteristics of high density, stable chemical properties and thermal properties and the like. The main fields of application are the petroleum industry and the chemical industry. In the oil industry primarily for oil and gas drilling mud weighting agents; in the chemical industry, barite is used as a raw material for manufacturing various barium-containing chemical products, such as barium carbonate, barium sulfate, barium oxide and lithopone (lithopone), and lithopone pigment is also used for manufacturing white paint, and has more advantages than the lithopone and the lithopone when used indoors.
The barite used in China is mainly a primary product, is used as a weighting agent for oil well slurry in large quantities, and is used for producing barium salt series chemical products in small quantities. For example, precipitated barium sulfate is produced by using barite (the main component is also barium sulfate BaSO)4) Adding carbon, reducing at high temperature to obtain barium sulfide, and reacting with sodium sulfate to obtain barium sulfate.
The main component of natural barite is barium sulfate (BaSO)4) And the content is not low and can reach more than 95 percent. However, the barite has poor color and insufficient whiteness due to the inclusion of color-forming substances such as iron. Generally, users using barium sulfate or barite have higher requirements on the whiteness index. Barite, as used in the paint industry, requires a whiteness of greater than 90%.
Therefore, the proper purification and whitening treatment of the natural barite can effectively improve the purity and whiteness of the barite, meet the requirements of many users and even achieve the use effect of the barium sulfate by a precipitation method.
However, much work has been done on the purification, purification and whitening of barite, such as reacting sulfuric acid with barite powder, or reacting hydrochloric acid with barite powder, or high temperature calcination, etc. However, these methods have more or less drawbacks, such as the slow reaction rate of sulfuric acid process for high iron content and long treatment time; the hydrochloric acid method has fast reaction, but if the residual mother liquor after the reaction is not cleaned completely, the color is easy to reappear; the calcination method consumes a large amount of energy.

In the method for purifying and whitening barite, in the step 2), the heating temperature is 60-90 ℃, and the reaction time is 1-2 hours.
In the method for purifying and whitening barite, in the step 3), vacuum filtration is adopted.
In the foregoing method for purifying and whitening barite, in the step 5), the barite is dried at a temperature of 110 ℃ and 130 ℃ until the water content is less than 0.5%.
The invention has the beneficial effects that:
1. according to the invention, the phosphoric acid, the hydrochloric acid and the fluoride are reasonably proportioned to prepare the purifying whitening agent with excellent performance, and the purifying whitening agent can form a good colorless complex with iron ions in the barite, so that a reaction liquid obtained by reaction is also in a colorless state, and the barite is not easy to reappear in color.
2. In the purification and whitening process, the reaction can be completed within 2 hours at most, the time is short, and the reaction is fast.
3. The invention uses phosphoric acid, hydrochloric acid and fluoride to carry out proportioning, wherein, only the cost of phosphoric acid is slightly high, but the content is only about 33 percent, therefore, the cost of the whole purifying whitening agent is not obviously increased, and the invention has the advantage of low cost.
