The Knelson™ Concentrator
A Genuine Canadian Success Story
Thirty years ago a pursuit to discover a ‘better way’ would revolutionize the application of gravity separation in the gold mining industry.
Today, this application continues to improve cash flow for operations around the globe.
Like many of his contemporaries, at the end of WWII Byron decided to leave his native Saskatchewan to seek his fortune on the west coast. With his life savings of several hundred dollars in his pocket, Byron made his way to Vancouver. Managing to make ends meet by taking on odd jobs Byron eventually found himself selling Kirby vacuum cleaners and later selling cars for a young entrepreneur of the same era named Jim Pattison.
In 1976 Byron tested the first crudely built fluid-bed prototype centrifugal concentrator at an aggregate plant in the Fraser Valley. Although the first unit lacked mechanical refinement of today’s carefully engineered units, the metallurgical performance of the unit set Byron Knelson on what would become an exciting and passionate 25 year journey that resulted in the commercialization of what has become an icon in the mineral processing industry in Canada and abroad – the Knelson™ concentrator.
