As the saying goes, rust never sleeps, but mine and plant operators are waking up to new technologies for controlling it

From a global mining viewpoint, corrosion of materials and equipment might best be described as a universal problem that demands localized solutions. Differences in ore characteristics, extraction processes and chemicals, or environmental conditions mean that a corrosion-preventative product that works well at one site might be less effective at another.

Although there are plenty of products available to help solve the industry’s corrosion concerns, it can be expensive to sink money into a one-size-fits-all solution that doesn’t meet the specific conditions of a particular problem. Experts say there is no simple rule of thumb for selecting the most suitable coating product or system. Taking into account the many factors that promote corrosion requires a disciplined approach to solve — or at least manage — corrosion problems.
