Quartz sand is one of the important non-metallic minerals. For quartz sand concentrators, daily management has a great impact on product conditions, economic benefits and other aspects.
Quartz Sand Mineral Processing Management Involves 5 Major Aspects
The daily management of a mineral processing plant involves many aspects, including mineral processing technology, mineral processing equipment, technical parameters, product standards, waste, etc.
Quartz sand mineral processing technology management
The quartz sand mineral processing plant should select appropriate mineral processing and purification processes and equipment through mineral processing tests and mine design based on factors such as raw material properties, product quality requirements, market demand, and investment budget, such as water washing, classification, scrubbing, magnetic separation, flotation, Acid leaching etc. At the same time, in daily management, the process flow should be adjusted in time according to the situation of quartz sand products.
Quartz sand mineral processing equipment management
Quartz sand mineral processing plants should strengthen the maintenance and repair of mineral processing equipment to ensure the normal operation and efficient use of equipment, reduce energy consumption and costs, and improve product quality and output. Quartz mineral processing plants need to pay attention to the maintenance and repair of the following mineral processing equipment:
- Ball mill: Ball mill is an important equipment for grinding ore. The temperature of the motor and bearings should be checked regularly, and lubricating oil should be added in time to prevent overheating and wear. The wear of the cylinder and lining should also be checked, damaged parts should be replaced in time, and the inside of the cylinder should be kept clean to avoid foreign matter affecting operating efficiency.
- Magnetic separator: A magnetic separator is a device that uses a magnetic field to separate minerals. The performance of the magnetic system should be checked regularly to maintain the stability of the magnetic field strength and gradient to prevent the gap between the magnetic poles from being too large or too small, which will affect the sorting effect. The operation of conveyor belts, rollers, scrapers and other components should also be checked and adjusted or replaced in time.
- Flotation machine: The flotation machine is a device that uses foam to separate minerals. The working status of the mixer, ventilator, scraper and other components should be checked regularly to maintain good mixing and ventilation effects and prevent too much or too little foam from affecting the quality of the flotation machine. Sorting effect. You should also check whether the connections and displays of circuits and instruments are normal, and troubleshoot in a timely manner.
- Filter: The filter is a device used for dehydration. The cleanliness of filter cloth, filter screen, filter cake and other components should be checked regularly and cleaned or replaced in time to prevent blockage and leakage. You should also check whether the pressure, temperature, flow and other parameters are normal, and adjust or repair them in time.
Quartz sand mineral processing technical parameter management
Quartz sand mineral processing plants should strengthen the monitoring and optimization of the mineral processing process and control the technical parameters of each process, such as water volume, concentration, temperature, time, dosage of chemicals, etc., to improve the mineral processing effect and recovery rate. The mineral processing technical parameters that should be monitored in quartz mineral processing plants include the following aspects:
- The particle size and fineness of crushing and grinding: affects the degree of dissociation and separation effect of minerals. Generally, the particle size after crushing is required to be less than 10mm.
- The amount, concentration and time of water for washing, grading and desliming: affect the degree of removal of impurity minerals and product quality. Generally, the washing concentration is required to be between 50% and 60%, the classification particle size is between 0.1 and 0.3mm, and the desliming time is required. Between 10-20 minutes.
- Scrubbing concentration, time and stirring intensity: Affect the removal effect of thin film iron and adhering impurities on the quartz surface. Generally, the scrubbing concentration is required to be between 50% and 60%, the scrubbing time is between 15-30 minutes, and the stirring intensity is 200 -300 rpm.
- The magnetic field strength, drum speed, ore feeding amount and sorting times of magnetic separation: affect the separation effect of magnetic impurity minerals. Generally, the magnetic field strength is required to be between 10000-13000 Oersted, and the drum speed is 60-320 rpm. between.
- Flotation agent type, dosage and concentration: Affects the flotation effect of non-metallic impurity minerals such as feldspar and mica. Generally, the agent type is a mixed collector of high-grade aliphatic amine salt and petroleum sodium sulfonate, and the dosage is 0.5- 1.5kg/ton, concentration 1%-5%.
- Acid type, dosage and concentration of acid leaching: affects the dissolution effect of metal impurities and gas-liquid phase impurities. Generally, the acid type is sulfuric acid, hydrochloric acid, etc., the dosage is 2-5kg/ton, and the concentration is 5%-10%.
Quartz sand product standard management
Quartz sand mineral processing plants should strengthen the testing and analysis of mineral processing products to ensure that the products meet quality standards and requirements, and timely adjust production plans and process parameters to adapt to market changes.
Waste management of quartz sand concentrator
Quartz sand mineral processing plants should strengthen the treatment and recycling of mineral processing wastewater, waste residue and other pollutants, reduce the impact and damage to the environment, and fulfill social responsibilities.
conclusion
The above are some contents about the management of quartz sand concentrator. The management of quartz sand concentrator is a systematic project that needs to be considered and optimized from multiple angles and levels to improve product quality and efficiency, meet market demand, and protect environmental resources. As a mineral processing plant manager, you should master the knowledge and skills in the above five aspects and continue to learn and innovate.
