Flotation Tank Wear Protection in Canadian Gold Mine

At an underground gold mine in Quebec, the 800m³ flotation cells processed sulfide-rich slurry with fluctuating pH levels (8-11). The original rubber liners suffered from delamination and detachment, leading to severe tank corrosion and unplanned maintenance.

A composite liner system was designed and installed:

1. Multi-Layer Structure:

   • Base Layer: 10mm impact-resistant steel plate

   • Wear Layer: 8mm polyurethane-ceramic hybrid material

   • Corrosion Barrier: Epoxy resin coating (acid/alkali resistant)

2. Quick-Installation Design:

   • Each module ≤ 25 kg for easy handling

   • Bolt-free locking mechanism

   • Installation efficiency improved by 60%

• 18 months of continuous operation with zero liner failure

• Corrosion rate measured at <0.15 mm/year

• Annual labor savings: 320 man-hours

• ROI period: 7.2 months
