Phenikaa secures low-iron silica sand for Cristobalite with CFlo's plug and play plant

Phenikaa Hue Mineral Processing (Vicostone Group) Hue Province, Vietnam Silica Sand

CFlo collaborated with Phenikaa Hue Mineral Processing, part of Vicostone Group, to design and install a 30-35 TPH silica sand processing plant in Hue Province, Vietnam. Launched in September 2024, the Micrograder BT50 supplies high-quality, low-iron silica sand for Cristobalite, a high-temperature polymorph of silica prized for refractory, ceramics, coatings and cosmetic applications.

The Challenge

Phenikaa acquired silica sand mines to secure raw material supply for operations across Southeast Asia and India, needing better control over silica sand quality and costs. Its previous reliance on external suppliers resulted in fluctuating costs and inconsistent quality, while Cristobalite production demands high-grade sand with low iron content, thermal stability, chemical resistance and fine particle properties.

The Solution

CFlo analysed Phenikaa's needs, conducted lab tests on their raw materials and installed the Micrograder BT50, a custom silica sand washing system delivering high-grade, low-iron sand. The integrated system handles feeding, trash removal, screening, washing, dewatering, stockpiling, water recycling and sludge management, fully automated for consistent product quality.

The plant was delivered with CFlo's Plug and Play technology: machine parts fully assembled, wired and tested at the factory, shipped in containers and connected on site like Lego blocks. This minimised complex on-site assembly and electrical work, enabling faster installation, reduced downtime and fewer issues. Phenikaa's team also visited a CFlo plant that had been operational for over five years before selecting CFlo.

The Results

Since the September 2024 launch, the plant has consistently produced low-iron silica sand meeting the high standards required for Cristobalite and other industrial applications, reduced operational costs through efficient power and water usage, and given Phenikaa a reliable, cost-effective silica sand supply chain.
