SAMPLE PREPARATION, ANALYSES AND SECURITY
The following section has been sourced from Eggleston et al. (2008) and Leroux (2008). The reader should refer to these reports for detailed information.
In order to process a significant amount of kimberlite, Shore purchased and commissioned a batch sampling process plant in order to process and recover diamonds. The process plant (and subsequent results) was designed to simulate a commercial kimberlite ore treatment plant. The general plant position relative to storage areas is shown in Figure 12.1.
Shore’s process plant was designed and constructed by Bateman Engineering PTY Limited (“Bateman”) of South Africa. Shore’s Bateman process plant (Bateman Reference Number M7007) consists of the following circuits:
a 30 t/h crushing circuit;
a 10 t/h Dense Media Separation (“DMS”) circuit which consists of a 250 mm DMS cyclone; and
a recovery circuit consisting of a Flow Sort® X-Ray diamond sorting machine (“Sortex”) and a grease table.
SHORE’S SAMPLE PROCESSING CIRCUIT
Figures 12.2 and 12.3 show a schematic flowsheet for the processing of kimberlite samples from both the underground and LDD drill programs. A detailed description of Shore’s processing and diamond recovery circuits can be found in Eggleston et al. (2008).
