Caso de recuperación de barita: Planta y equipos de proceso

Introducción
Barita, a critical non-renewable mineral resource, plays an indispensable role in industries such as oil & gas drilling, barium chemicals, and fillers. With increasing demand and finite natural reserves, efficient barite recycling has become essential to sustain industrial needs while minimizing environmental impact. This case study examines a 15TPH barite recovery plant in Morocco, showcasing the process flow, equipment used, and considerations for optimal recovery.

¿Por qué reciclar barita?

Drilling Mud Weighting Agent: In some oil wells and gas wells, drilling mud and clay have a specific gravity of about 2.5, and water has a specific gravity of 1, so the specific gravity of the mud is low. Sometimes the mud weight cannot be balanced with the underground oil and gas pressure. Cause a blowout accident. In the case of high underground pressure, it is necessary to increase the specific gravity of the mud. Adding barite powder to the mud is an effective measure to increase the specific gravity of the mud. The density of barite is high. Nearly 90% of the barite produced in the world is used as drilling mud for oil and natural gas. The production of barite is closely related to the rise and fall of the oil and gas drilling industry.

Price Volatility & Scarcity: La barita se utiliza principalmente en los lodos de perforación petrolífera, por lo que el precio del petróleo y la demanda de barita están estrechamente relacionados. Los actuales precios mundiales del petróleo siguen siendo altos, y muchos países se plantean reforzar la exploración y explotación petrolíferas, lo que inevitablemente provocará un aumento de la demanda mundial de barita.

With the uncontrolled development of barite minerals, resulting in a serious shortage of barite resources, the price of barite powder has risen again and again. Many oil companies have been helpless and have begun to find barite recycling methods, but with little effect. At present, some petroleum companies separate the barite from the waste liquid and then add it to the mixing station to mix with the newly added barite powder and mud. It is hoped that the barite can be recycled by this method. But different from the newly added barite, the recovered barite becomes very smooth under the action of friction during drilling and has an oil film attached to its surface, which follows the wall of the mixing tank under the action of the high-speed rotating mixer. It sinks to the bottom of the tanque de mezcla, so it is not feasible to recycle the barite by stirring; in most cases, the barite is thrown away once it is used, which not only wastes resources but also has an impact on the environment. Therefore, barite recycling is necessary to save resources and reduce the impact on the environment.

Explicación de la planta de procesamiento de barita

1. The size of the barite raw material is less than 8mm. Load the raw material into the hopper.
2. Utilice la alimentador vibratorio electromagnético to feed the barite raw material to the belt conveyor until the trommel scrubber.
3. The under-screen (0- 2 mm) slurry of the lavador trómel will go to a distribution tank and be fed to three sets of shaking tables.
4. The over the screen (2-8mm) of the trommel scrubber will flow to the separador jig.
5. The concentrate from the shaking tables and jig separator will go to a concentrate pond and be pumped to a concentrate dewatering screen.
6. The over-concentrate dewatering screen materials are concentrates will be conveyed away by belt conveyor to the concentrate zone.
7. The under-concentrate dewatering screen materials will be pumped back to the trommel scrubber by a sand pump.
8. The tailings of shaking tables and jig separator will go to a tailings pond and be pumped to a tailings dewatering screen.
9. The over-tailing dewatering screen materials, waste sand, will be conveyed away by belt conveyor to the waste zone.
10. The under-tailing dewatering screen materials will be pumped to the hidrociclón by a sand pump.
11. The underflow of the hydro cyclone will flow to the tailings dewatering screen.
12. The overflow of the hydro cyclone will flow to clarifiers.
13. The mud outlet of the clarifiers will go to a mud tank.
14. The mud in the mud tank will be pumped to the filter press by a filter press feed pump.
15. The clean water from the filter press and the clean water from the clarifier will be joined together and go to water tanks.
16. El agua de los tanques de agua se bombeará de nuevo al lavador trómel mediante una bomba de agua.

The above barite process plant does not use equipo de trituración because the raw material in this case is 0- 8 mm. For larger mining ore, 3 crushers are recommended.

Recommended Rock Crushers

Trituradora de mandíbulas

This is traditional equipment that is used by many users. It is very suitable for processing barite. The main features of a trituradora de mandíbulas are:

1. El componente central del equipo es la placa de mandíbula, que es accionada por el motor para hacer que las placas de mandíbula se aprieten entre sí para completar la operación de trituración, por lo que su descarga es más uniforme.
2. Existen muchos tipos de materiales procesados por este equipo. Además de barita, también puede triturar materiales de la misma dureza, como mármol, basalto, piedra caliza, etc.
3. Como los usuarios cada vez exigen más a este aparato, se ha mejorado mucho su función, rendimiento y estructura, por lo que su índice de aplicación es alto.

Trituradora de cono

En trituradora de cono is a type of equipment with high technological content in the crushing field. It has the following advantages in the processing of barite:

1. Este dispositivo adopta una estructura tridimensional, por lo que su espacio se reduce gradualmente, pero el rendimiento es cada vez más perfecto, y la función es cada vez mayor, lo que puede satisfacer las necesidades reales de aplicación de los usuarios.
2. Its production capacity is very large. In the process of developing this equipment, we attach great importance to the production capacity of the equipment, so its work efficiency will be higher, and the output will reach the ideal application standard of the user.
3. La relación de trituración es una magnitud física que mide si el equipo de trituración descarga uniformemente. Cuanto mayor sea la relación de trituración, más fina será su descarga. De lo contrario, el estado de funcionamiento del equipo es muy estable, y se puede obtener la ventaja de la relación de trituración. reflejar.

Molino Raymond

Since barite is a non-metallic mineral, it is reasonable to process it with a Molino Raymond. This equipment has the following advantages:

1. El equipo puede realizar la función de auto-ajuste para que pueda satisfacer las diferentes necesidades de los usuarios en términos de descarga, por lo que su tasa de utilización integral será mayor, y será capaz de desempeñar un mayor valor práctico.
2. En comparación con los equipos de la generación anterior, el factor de seguridad de este equipo es muy alto. Hemos instalado un circuito de protección alrededor del motor del equipo para que pueda desempeñar un papel decisivo en la protección del equipo y evitar daños mayores al equipo.
3. En el proceso de desarrollo de los equipos, tenemos un control de calidad muy estricto. Nos esforzamos por alcanzar la perfección en cada proceso y procedimiento, por lo que su vida útil es más larga, y se puede utilizar durante 8-10 años en comparación con equipos similares.

Conclusión

This Moroccan case demonstrates how a tailored 15TPH barite recovery plant integrates scrubbing, gravity separation, and water recycling to maximize resource reuse. For operations with larger ore (> 8 mm), supplementary crushers like jaw/cone crushers or Raymond mills are recommended.

Sustainable barite recovery not only conserves dwindling reserves but also aligns with environmental goals. For customized solutions, consult expert manufacturers like Máquina JXSC to optimize your barite recycling process.
