YINGCAI Ceramic Filter Plate Cleaner Replaces Nitric Acid in a Sichuan Concentrate Plant Environmental Upgrade Project

A concentrate processing enterprise in Sichuan recently adopted YINGCAI ceramic filter plate cleaner as a replacement for traditional nitric acid cleaning. The project helped the customer solve long-term problems in ceramic filter maintenance, hazardous chemical management, wastewater treatment, and production efficiency, becoming a practical example of green upgrading in mineral processing.

In concentrate production, ceramic filter plates are often blocked by mineral sludge, fine particles, impurities, and metal deposits after long-term operation. Traditional nitric acid cleaning can restore filtration performance to some extent, but it also brings serious risks.

Nitric acid is highly corrosive and may cause irreversible damage to ceramic filter plates, shortening equipment service life and increasing replacement and maintenance costs. At the same time, wastewater generated from nitric acid cleaning often contains acidic substances and heavy metal ions, making treatment more difficult and costly. As a hazardous chemical, nitric acid also creates safety risks during storage, transportation, and on-site use.

To address these challenges, YINGCAI New Materials provided a customized ceramic filter plate cleaning solution for the Sichuan concentrate plant, helping the customer move away from strong acid cleaning toward safer, cleaner, and more efficient maintenance.

Technical Highlights

YINGCAI ceramic filter plate cleaner is designed for deep pore cleaning and filtration performance recovery. The formulation helps dissolve and remove mineral sludge, metal deposits, and impurities blocked inside the micropores of ceramic filter plates.

Compared with nitric acid cleaning, the product is milder and more compatible with ceramic filter materials. It helps reduce corrosion risks, protect the original pore structure, and extend the service life of filter plates by more than 30%.

The solution also includes full-process technical support. From on-site inspection and cleaning plan design to product delivery, operation guidance, effect tracking, and process optimization, YINGCAI provided closed-loop service to ensure stable implementation and measurable results.

In wastewater management, the supporting treatment process helped the customer handle cleaning wastewater through precipitation, filtration, and purification. Useful components in the wastewater could be further recovered and reused, while the final wastewater indicators met environmental discharge requirements, reducing the pressure of waste acid treatment.

Application Value

After the solution was implemented, the Sichuan concentrate plant achieved clear improvements in safety, environmental protection, equipment maintenance, and production efficiency.

In environmental management, the company reduced its dependence on nitric acid and lowered hazardous chemical risks in production. The cleaner maintenance process helped support cleaner production and improve environmental compliance performance.

In economic performance, equipment maintenance costs were reduced by about 40%, and wastewater treatment costs were reduced by about 60%. With improved filtration efficiency, daily concentrate output increased by 8%, creating additional annual economic benefits of more than RMB 2 million.

The solution also reduced corrosion-related equipment damage and helped maintain more stable filtration performance. This improved production continuity and lowered the long-term cost of ceramic filter operation and maintenance.

Industry Significance

The successful application of YINGCAI ceramic filter plate cleaner in this Sichuan concentrate plant provides a practical and replicable path for mineral processing enterprises seeking to replace nitric acid cleaning.

For concentrate plants, metal mines, non-metallic mines, ceramic filtration systems, and solid-liquid separation processes, the solution provides value in deep pore cleaning, nitric acid replacement, equipment life extension, wastewater treatment cost reduction, hazardous chemical risk control, and green production transformation.

YINGCAI New Materials will continue to focus on industrial environmental cleaning technologies and provide safer, more efficient, and more sustainable cleaning solutions for mining and industrial customers.
