Mining and MineralsDiamond Recovery and Processing
Diamond recovery is unusual in that the product is a small number of individual objects rather than a mass of metal, which makes liberation without breakage, and security, the two governing concerns. This course covers both. Delegates work through kimberlite and alluvial deposit types, comminution designed to liberate rather than to grind, and dense medium separation as the main concentration step. Recovery follows: X ray and grease based sorting and the final recovery area. Security and the closed circuit that protects it are treated in detail. Diamond valuation, sizing and quality grading are covered at an operational level. The course closes on regulatory obligations including certification of origin.
