- Buyer's Guide
Name: Mario Guilherme Rupf
Job Title: Mechanical Engineer
Company: Kinross Gold Corp.
Location: Minas Gerais, Brazil
Length of Service: 3 years
In 2013, Mario Rupf began working as a mechanical engineer at Kinross Gold’s Paracatu mine in Minas Gerais, Brazil. During his first year, Kinross experienced production losses of more than $2 million due to 79 lubrication failure events. These failures were determined to be caused by incorrect drum storage, improper filtration, oil contamination and pump wear. Rupf and his team soon implemented an improvement plan, which included using lubricant identification labels, creating new points for oil sample collection, installing breathers and quick couplers, redesigning filter elements, and developing new routes for inspection and oil analysis. The results have been impressive. By 2015, production losses had been reduced to just seven lubrication failures, while revenue increased by more than $2.8 million. Reliability has also increased by nearly 50 percent. Rupf believes one of the biggest changes has been in the Kinross culture, where the relevance of lubrication is now recognized and employee morale has greatly improved.
