摘要
A method of separating heavy mineral particles, such as zircon, monazites, xenotime etc., from a sample of quartz crystal powder, comprises the steps of: a. conditioning the quartz powder suspected of containing heavy mineral particles as an aqueous pulp using a froth-flotation agent; b. subjecting the conditioned pulp to froth flotation to obtain a tailing; c. combining the tailing with an aqueous solution having a density greater than that of quartz and less than that of a heavy mineral which it is desired to separate; and d. centrifuging the combination. The separated heavy mineral crystals can then be characterised using a micro- analysis technique.
