Figure 1: Early Years Blend Composite locked-cycle flotation test work showing concentrate nickel grade versus. nickel recovery. Source: Bureau Veritas Minerals Pty Ltd, Project No. 4668, Locked Cycle Test 2 (LCT2 EYBC). The Locked Cycle Test final product result is based on the average performance of cycles 4 to 6 of the test, at steady state. The Locked Cycle Test curve is derived from the rougher concentrate only and the high-grade concentrate streams of the same test for the same cycles 4 to 6. The curve also reflects and is validated by the open-cycle testing results on the same Early Years Blend Composite sample.
