Cost-Effective and Efficient Design

Founded in 1993, Kinross Gold Corporation is a gold mining company with a diverse portfolio of projects throughout the United States, Brazil, Chile, Ghana, and Mauritania. Headquartered in Toronto, Canada, Kinross employs approximately 9,000 people worldwide.

The Round Mountain Mine is an open pit mine in central Nevada, one of the most prolific mining districts in the world. Round Mountain uses conventional open-pit mining methods and processes ore by milling and heap leaching.

Round Mountain Gold Corporation hired Morrison-Maierle to design the expansion of an existing scavenger flotation circuit at the Round Mountain Mine. The project’s purpose was to add flotation capacity to increase gold recovery in the mill.

Morrison-Maierle provided detailed engineering, construction phase support, and commissioning support. A few highlights of the project included:

  • To reduce costs and meet the owner’s needs in terms of overall capital expense, during the preliminary engineering of the project, we determined that we could eliminate the pre-engineered metal building that enveloped the expansion of the flotation circuit.
  • We conducted a trade-off study to study the effects of four 160 cubic meter rougher cells versus three 200 cubic meter rougher cells. Going with three larger cells yielded the same processing capacity and recovery results with a $500k savings to the project budget.
