Application of Filter Press in Gold Refining and Electronic Waste Recycling

Filter presses are widely recognized as efficient solid–liquid separation equipment and are indispensable in chemical, food, pharmaceutical, and mining industries. In gold processing, a filter press plays a critical role in both gold concentrate dewatering and electronic waste recycling, improving recovery rates, reducing moisture content, and ensuring environmental compliance.

Gold Concentrate Dewatering with Filter Press

In gold concentrate processing, membrane filter presses are typically used to remove water from the filter cake. High-pressure filtration produces a drier solid product while maximizing the recovery of rich liquor.

For tailings with lower moisture requirements, chamber filter presses are generally sufficient. The high efficiency, durability, and precise filtration of a filter press make it ideal for these demanding operations.

Gold Recovery from Electronic Waste

With the rapid growth of electronic products, recovering gold from electronic waste such as circuit boards, chips, and industrial slag has become increasingly important.

The process generally involves:

• Raw material pretreatment

• Chemical dissolution

• Gold precipitation

• High-temperature purification

During chemical dissolution, strong acids such as aqua regia dissolve base metals, leaving gold insoluble and producing a gold-containing waste liquid. This waste liquid is then filtered using a filter press to separate solids and recover valuable gold efficiently.

Design Considerations for Filter Press in Gold Refining

Gold-containing waste liquid is highly corrosive due to residual aqua regia. KERTE filter press systems are designed with:

• Embedded, sealed filter plates with concealed drainage to prevent leaks

• Stainless steel construction to resist corrosion and extend service life

These features reduce liquid loss, minimize environmental pollution, and ensure safe, reliable operation in aggressive chemical environments.
