ApplicationCeramic filter cleaning for iron ore beneficiation plants, ceramic filter plate cleaning, iron concentrate dewatering, tailings recovery filtration, and strong acid cleaner replacement
Project background
Project Type:
Special cleaning upgrade project for ceramic filters in green mining applications, including eco-friendly cleaner replacement and cleaning process optimization.
Project Location:
A large iron mine in Zibo, Shandong, China.
Application Scenario:
The project focused on ceramic filter element cleaning in the ore beneficiation workshop, covering iron concentrate filtration and tailings recovery filtration sections. The solution was designed to remove mineral sludge blockage, scale adhesion, and reagent residues from ceramic filter surfaces through regular cleaning with an eco-friendly cleaning agent, ensuring stable and efficient filter operation while meeting green mining environmental requirements.
Project Scale:
The solution was applied to 8 ceramic filters in the workshop. The main equipment model was TC-120, with a filtration area of 120 m² per unit. The system was equipped with 2 eco-friendly cleaning agent storage tanks, each with a capacity of 5 m³. One cleaning operation covered 8 ceramic filters, with a total filtration area of approximately 960 m². Regular cleaning was carried out twice per month to support stable year-round operation.
Project introduction
The customer is a large iron mine located in Zibo, Shandong, and a local green mining pilot enterprise. The company is mainly engaged in iron ore mining, beneficiation, and iron concentrate production. In the beneficiation workshop, 8 ceramic filters are used for iron concentrate dewatering and tailings recovery filtration.
Before the upgrade, the customer had long used traditional strong acid cleaners. This caused several key problems. First, the cleaner was highly corrosive and easily damaged the ceramic filter elements and glaze layer, shortening the average filter element service life to less than 8 months and increasing replacement costs. Second, the cleaning wastewater contained acid and heavy metal ions, resulting in high treatment costs and environmental discharge risks. Third, the cleaning effect was unstable. Mineral sludge, scale, and reagent residues were difficult to remove completely, leading to lower filtration capacity, higher moisture content in concentrate, and reduced beneficiation efficiency.

To solve these problems, YINGCAI developed a green cleaning solution for ceramic filters in mining applications. The solution used an eco-friendly cleaning agent with no heavy metals, low COD, good biodegradability, and strong scale-removal performance. It was designed to replace traditional strong acid cleaners while achieving efficient cleaning, environmental compliance, energy saving, and lower maintenance costs.
During project implementation, YINGCAI organized a technical team to inspect the pollution condition of the ceramic filter elements and evaluate the original cleaning process. Based on the test results, the team optimized key parameters such as cleaner concentration, cleaning temperature, cleaning time, and rinsing process.
After that, the team completed installation of the cleaning agent storage tanks, dosing adjustment, process commissioning, and operator training. A regular inspection mechanism was also established, allowing the cleaning plan to be adjusted dynamically according to the actual pollution level of the filter elements. The whole project took only 15 days from solution design and on-site commissioning to formal operation, without affecting the customer’s normal production.
Customer value
After the project was put into operation, the customer achieved significant improvements in environmental compliance, cost reduction, production efficiency, and equipment stability.
Environmental Value:
The eco-friendly cleaner contains no heavy metals and has low COD. Cleaning wastewater pH was controlled between 6.5 and 8.5, requiring no complex neutralization treatment and allowing the wastewater to enter the existing mine wastewater treatment system. Compared with traditional strong acid cleaning, the project reduced wastewater treatment chemical consumption by approximately 1.8 tons per year and reduced COD emissions by about 0.6 tons, helping the customer pass green mining environmental acceptance.
Economic Value:
The average service life of ceramic filter elements was extended from less than 8 months to about 18 months, reducing annual filter element replacement by 48 pieces and saving approximately RMB 288,000 in replacement costs. Cleaning chemical consumption was reduced by about 15%, saving approximately RMB 57,600 per year. Wastewater treatment cost was reduced by about RMB 32,000 per year.
At the same time, filter operating efficiency increased by about 12%, concentrate moisture content decreased by 3 percentage points, and approximately 2,000 tons of additional iron concentrate were recovered annually, creating about RMB 1.2 million in added value. Overall, the project helped the customer save costs and increase revenue by approximately RMB 1.5706 million per year, with a strong return on investment.
Production Value:
The cleaning process is mild and does not damage ceramic filter elements. It reduced filter cracks, leakage, equipment failures, and unplanned maintenance caused by aggressive acid cleaning. Equipment repair frequency was reduced, and each maintenance reduction saved approximately 4 hours of shutdown time, increasing effective annual production time by about 96 hours.
The solution also improved filtration stability, helped maintain stable product quality, reduced follow-up drying and transportation costs, optimized the beneficiation process, lowered operator workload, and supported safer, more stable, and more efficient mine operation.
