GFS Mineral Storage Tanks: Secure, Corrosion-Resistant Solutions for Modern Industry by Center Enamel

In today’s resource-driven global economy, the secure and contamination-free storage of minerals, slurries, and mineral-rich liquids is a critical need across mining, chemical, energy, and process industries. Corrosive environments, fluctuating pH, mechanical abrasion, and strict regulatory standards all pose unique challenges to conventional tank materials. As a leader and innovator in tank engineering, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) has developed the Glass-Fused-to-Steel (GFS) mineral storage tank—a technology that unites the structural strength of steel with the chemical resilience of industrial glass.

As a leading storage tank manufacturer worldwide. Center Enamel can provide Glass Lined Steel(GLS) tanks, fusion bonded epoxy tanks, stainless steel tanks, galvanized steel tanks, welded steel tanks and aluminum geodesic dome roofs, Wastewater and Biogas Project Equipments for global customers.

1. The Growing Demands of Mineral Storage

Mineral processing and mining operations produce, handle, and store a diverse array of mineral products:

· Dry powders (e.g., potash, cement, salt, gypsum, lime)

· Slurries and liquid concentrates

· Intermediate process byproducts

· Reagents and corrosive chemicals used in mineral separation

· Tailings and waste byproducts containing aggressive compounds

Safe mineral storage must meet these requirements:

· Robust corrosion and abrasion resistance

· Leak-free and gas/vapor-impermeable containment

· Long service life under pH extremes and temperature swings

· Minimal maintenance requirements to reduce cost and downtime

· Compliance with international environmental and safety codes

2. Why Glass-Fused-to-Steel (GFS) for Minerals?

GFS technology combines carbon steel panels with a molten glass coating applied and fused at high temperatures (820–930°C). This creates a robust, glossy, and inorganic barrier on both tank interior and exterior, forming a single, integrated structure.

Core Advantages for Mineral Storage

· Extreme Corrosion and Chemical Resistance: Glass enamel is inert to acids, alkalis, salts, and oxidants, protecting against a broad range of mineral chemicals and reagents (pH 1–14 possible).

· Abrasion Resistance: The glassy surface resists mechanical wear, essential for the storage of abrasive mineral particulates or slurries.

· Long Service Life: Over 30 years of operation—surpassing lined steel, epoxy, or concrete alternatives.

· Gas and Liquid Impermeability: Enamel is non-porous and prevents the movement of gases or liquids through the tank wall, minimizing environmental impact.

· Hygienic, Easy-to-Clean Surface: The smooth glass finish simplifies washdowns, resists scaling and caking, and curtails microbial growth.

· No Repainting, Low Maintenance: Unlike steel or epoxy tanks, GFS tanks never require recoating or lining renewal, reducing long-term expense.

· Fast, Modular Construction: Bolted panels permit rapid site assembly, scalability, and easy transport—even for remote mine sites.

3. Technical Excellence: Center Enamel’s Manufacturing

· Steel Grades: High-strength, enamel-grade carbon steel (3–12 mm thick), pre-treated by shot blasting, CNC cut for perfect fit.

· Dual Glass Enameling: Both sides of each panel receive 0.25–0.45mm of proprietary glass; fired in factory kilns for total fusion.

· Accessories: Geodesic domes, conical or flat roofs, ladders, platforms, outlets, mixers, valves, manways, instrumentation ports, and more.

· Color Options: Black blue, grey olive, forest green, cobalt blue, desert tan, and client-specified shades.

· Testing and Quality Control:

o Acid/alkali soak tests (pH 1–14)

o Adhesion (≥3450 N/cm²)

o Mohs hardness (6.0)

o Spark test (>1,500V)

o Certification to AWWA, ANSI, EN, OSHA, ISO9001, NSF, and more.

4. Comparison: GFS vs. Conventional Tanks

Feature	GFS Mineral Tank	Epoxy Steel	Concrete	FRP/Plastic

Abrasion Resistance	High (Mohs 6.0)	Medium	Poor (erodes/cements)	Low
Maintenance	Minimal	Repainting/patching	Frequent repairing	Cracking, UV, repair
Installation Speed	Fast, modular	Moderate	Slow, on-site cures	Moderate/fittings
Service Longevity	>30 years	8–15 years	10–20 years	5–10 years
Customizability	Very high	Medium	Limited	Limited
Environmental Impact	Low, recyclable	High (waste/solvent)	High CO2, big shells	Moderate

5. Application Scenarios

· Mining & Ore Processing: Bulk minerals, concentrate and slurry tanks, reagent storage.

· Chemicals: Aggressive acids, chlorides, oxidizing agents, or alkaline materials.

· Industrial Processing: Cement plants, fertilizer, food-grade minerals.

· Waste Management: Tailings, hazardous waste, leachate from landfills.

· Municipal: Sand, salt or de-icing storage, filtration media, or treatment reagents.

6. Performance and Compliance

· Designed and certified to AWWA D103-09, OSHA, ISO 9001, EN 28765, NSF/ANSI 61, WRAS, FM, LFGB, and meets risk, seismic, wind, and occupancy codes for all locales.

· Suits capacity ranges from 20 m³ “silos” to mega-tanks exceeding 100,000 m³.

· Fitted foundation options: steel or embedded rings, slabs, or specialized bases.
