Flotation Cell Repair
Brushable Ceramic and Ultra Quartz
January 1998
Noranda Mine (Brunswick Mine Division)
Mining
Problem:
Floatation Cells see tremendous corrosion by the fact that the ore is abrading the sides of the tanks
constantly! Any coating you apply must have great abrasion resistance. Galvanic corrosion occurs at the
steel surfaces rather quickly once abrasion starts! The floor of the Floatation Cell sees the sediment of the
ore which is very abrasive, and needs repairing regularly.
Solution:
The Flotation Cells are first blasted to a SSPC -SP5 white metal blast to remove all corrosion from the
surface. Any large holes are filled in with Titanium Putty. Next Brushable Ceramic is rolled onto the area
using a 1/4” nap roller. Two coats are recommended . Each at 14-18 mils thick. Between coats the
coating is checked for a “holidays” with a Leak Detector Kit. The finish coating provides a tough durable
abrasion resistant finish against the aggregate. The floor is troweled with 3/8” of Ultra Quartz for final
protection. The Ultra Quartz is troweled up the side wall approximately 4 inches for a seamless finish.
