Phosphate Flotation Circuit

Vernal Phosphate Mine, Utah

Simplot Phosphates, at their Vernal Mine Mill Building had undertaken a project to install a flotation circuit to separate the fine phosphate ore from the tailings stream. The flotation circuit was to be installed on the third level deck of 80’ tall New Concentrator building. The flotation circuit equipment, tanks, piping and structure was estimated to weigh over 1 million pounds.

UELS was responsible for the structural engineering of the project to support the flotation circuit. This required that the majority of the beams, girders, and columns supporting the third level deck be retrofitted to increase the capacity of the supporting structure. UELS used structural analysis software to calculate the load and design the steel retrofit sections. Detailed construction plans were prepared that depicted the retrofit welding and construction procedures to install the retrofit sections.
