Engineered bolted steel storage systems tailored for aggressive mining applications, high-salinity wastewater, and process water circulation.
Modern mining and mineral processing operations function under some of the most rigorous environmental and mechanical conditions on earth. From remote high-altitude copper mines in the Andes to deep underground gold recovery plants in Western Australia, containment systems represent a critical operational infrastructure. Steel storage tanks are no longer simple static vessels; they are highly engineered nodes in complex chemical processing, environmental remediation, and hydrological management circuits.
The global mining sector faces unprecedented challenges: declining ore grades require larger processing volumes, water scarcity demands closed-loop recycling systems, and strict environmental liabilities mandate bulletproof containment of toxic reagents and tailings. In this context, conventional concrete tanks or field-welded steel tanks often fail to meet the rapid deployment and corrosion resistance parameters required by modern operators.
Corrosive chemical reagents such as sulfuric acid, copper sulfate, sodium cyanide, and various xanthates are routinely used in flotation and leaching circuits. Traditional carbon steel tanks degrade rapidly under these conditions, leading to catastrophic structural failures, environmental contamination fines, and costly operational shutdowns. Consequently, the industry is transitioning toward advanced modular bolted steel tanks featuring specialized coatings, such as Glass-Fused-to-Steel (GFS) and Fusion-Bonded Epoxy (FBE).
Engineered to meet the demands of modern industry, LIDA Bolted Tank delivers durable, code-compliant storage systems for liquid and dry materials. Explore our full range of bolted steel tanks and custom-built solutions.
Understanding the precise chemical and physical dynamics of mineral processing is crucial for selecting the correct tank configuration. LIDA TECH's steel bolted tanks are engineered to address specific pain points across multiple stages of mining operations.
Tailings—the byproduct of mineral extraction—consist of finely ground rock, chemical processing fluids, and water. These slurries are highly abrasive and frequently alkaline or acidic. Bolted steel tanks are utilized as thickener feed wells, overflow tanks, and slurry surge tanks. The abrasive nature of slurry requires coatings that have high physical hardness. Glass-Fused-to-Steel (GFS) tanks are particularly suited here; the glass lining has a hardness of 6-7 on the Mohs scale, providing excellent resistance to abrasive particulates suspended in slurry flows. Furthermore, the modular design allows for the installation of heavy internal wear plates near inlet structures where kinetic energy is highest.
In hydrometallurgy, metals are extracted from ore using aqueous chemical solutions. For instance, in gold cyanidation, dilute sodium cyanide is used to leach gold from the ore matrix. In copper heap leaching, sulfuric acid is sprayed over ore pads to dissolve copper minerals. The resulting solutions (Pregnant Leach Solution, or PLS) are highly corrosive and chemically active. Steel storage tanks used to store PLS and Barren Leach Solutions (BLS) must feature premium chemical barrier coatings. Our Fusion-Bonded Epoxy and Glass-Fused-to-Steel tanks prevent any chemical interaction between the acidic or basic solutions and the structural steel shell, ensuring complete system integrity and preventing soil contamination.
Acid Mine Drainage is one of the mining industry's most severe environmental challenges. AMD occurs when iron sulfide minerals are exposed to air and water, creating highly acidic, metal-rich runoff. LIDA TECH GFS and Stainless Steel tanks are deployed globally in active AMD treatment plants. These tanks serve as neutralization reactors where lime slurry is added to raise pH levels, precipitating heavy metals out of solution. The tanks must resist extreme pH variations (from pH 2 to pH 11) within the same process cycle, a requirement easily met by the chemical inertness of our glass-fused technology.
Beyond liquid containment, mineral operations require robust dry bulk storage for processed concentrates (e.g., copper, zinc, lead concentrates) and processing reagents (such as quicklime and soda ash). Dry bulk steel silos must handle massive dynamic loads during filling and discharge cycles, along with potential dust explosion hazards. LIDA's bolted dry bulk tanks are structurally calculated using advanced finite element analysis (FEA) to withstand high lateral pressures, ensuring structural stability while offering smooth internal surfaces that prevent material bridging or ratholing.
Custom-engineered containment systems serving municipal infrastructure, industrial wastewater treatment, energy recovery, and mineral processing sectors.
The global mining landscape is shifting rapidly toward sustainable practices and digitalized operations. Containment engineering has adapted accordingly, focusing on modularity, zero-liquid-discharge (ZLD) integration, and corrosion-free materials.
Historically, field-welded carbon steel tanks were the industry standard. However, the mining industry's geographical migration to remote, logistically challenging areas (such as high-altitude regions in Chile or desert landscapes in sub-Saharan Africa) has made field welding increasingly impractical. Field welding requires highly skilled labor, extensive quality assurance testing (such as radiographic testing of welds), and prolonged construction schedules under unfavorable weather conditions.
Modular bolted steel tanks solve these logistical hurdles. The tank panels are manufactured and coated in a controlled factory environment, packed compactly into standard shipping containers, and shipped directly to the mine site. Assembly requires no hot work, relying instead on high-strength structural bolts and specialized elastomeric sealants. This reduces site installation time by up to 60%, significantly lowering capital expenditures (CAPEX) and reducing on-site safety risks.
In highly acidic mining processes, material selection is critical. GFS technology fuses borosilicate glass onto steel plates at temperatures exceeding 800°C, creating a chemical bond that combines the strength of steel with the chemical inertness of glass. This composite material is highly resistant to acids, alkalis, and mechanical wear. For less aggressive applications, such as process water storage or dry bulk containment, Fusion-Bonded Epoxy (FBE) offers a cost-effective alternative with excellent corrosion protection, impact resistance, and durability under cyclical thermal loading.
Environmental regulations now require many mines to operate under Zero Liquid Discharge mandates, meaning all process water must be treated and recycled within the facility. This creates highly concentrated brine streams that are stored in wastewater tanks. These high-salinity brines are highly corrosive to standard metals. Our advanced epoxy-coated and GFS bolted tanks are designed to handle these concentrated streams, supporting mining operations in meeting strict environmental standards without risking leakage or structural degradation.
