Silica sand is one of the important non-metallic minerals. For silica sand mineral processing plants, daily management has a great impact on product conditions, economic benefits, etc. Daily management of mineral processing plants involves many aspects, including mineral processing technology, mineral processing equipment, technical parameters, product standards, waste, etc. This article will describe how these aspects affect the quartz sand concentrator.

01Silica sand 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.

02Silica sand mineral processing equipment management

Silica 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:

01 Ball mill:

The 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.

02Magnetic separator:

Magnetic separators are equipment that use magnetic fields to separate minerals. The performance of the magnetic system should be checked regularly to keep the magnetic field strength and gradient stable and 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.

03 Flotation machine:

The flotation machine is a machine that uses foam to separate minerals. The working status of the agitator, ventilator, scraper and other components should be checked regularly to maintain good stirring and ventilation effects and prevent too much or too little foam from affecting the sorting effect. You should also check whether the connections and displays of circuits and instruments are normal, and troubleshoot in a timely manner.

04 Filter:

The filter is a device used for dehydration. The cleanliness of the 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.

03Silica sand beneficiation technical parameter management

Silica 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:

01Particle size and fineness of crushing and grinding

It affects the degree of dissociation and sorting effect of minerals, and generally requires the particle size after crushing to be less than 10mm.

02Water volume, concentration and time for washing, grading and desliming

Affecting the removal degree of impurity minerals and product quality, it is generally required that the water washing concentration is between 50% and 60%, the classification particle size is between 0.1 and 0.3mm, and the desliming time is between 10 and 20 minutes.

03 Scrubbing concentration, time and stirring intensity

The removal effect of thin film iron and adhering impurities that affect the quartz surface generally requires a scrubbing concentration of 50%-60%, a scrubbing time of 15-30 minutes, and a stirring intensity of 200-300 rpm.

04 Magnetic field strength, drum speed, ore feeding amount and number of separations of magnetic separation

To affect the separation effect of magnetic impurity minerals, the magnetic field strength is generally required to be between 10,000-13,000 Oersted and the drum speed to be between 60-320 rpm.

05 Types, dosage and concentration of flotation agents

In order to affect the floating effect of non-metallic impurity minerals such as feldspar and mica, the general requirement is that the agent type is a mixed collector of high-grade aliphatic amine salt and sodium petroleum sulfonate, the dosage is 0.5-1.5kg/ton, and the concentration is 1%-5 %.

06Acid type, dosage and concentration of pickling

To affect the dissolution effect of metal impurities and gas-liquid phase impurities, the acid type is generally required to be sulfuric acid, hydrochloric acid, etc., the dosage is 2-5kg/ton, and the concentration is 5%-10%.

04Silica sand product standard management

Silica 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.

05Waste management of quartz sand concentrator

Silica 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.

The above are some contents about the management of silica 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.
