Abstract

DELLAS, G.. Diamond plant statistics, process efficiencies, liberation modelling, and simulation: The art of the possible. J. S. Afr. Inst. Min. Metall. [online]. 2020, vol.120, n.10, pp.561-568. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/1213/2020.

The paper brings together the language of diamond numbers and the underlying principles for calculation of diamond liberation, followed by estimation of process efficiency at circuit and complete plant levels. In this way it provides a reference point, albeit a mixture of the theoretical and empirical, to assess the effectiveness of diamond plant accounting systems in the field. Having established today's baseline, the wider aim is ongoing education, peer technical debate, and progression to a more exact science.

Keywords : diamonds; liberation; recovery; modelling.
