- Testing was conducted on 5.4 t of material sieved to three size fractions: +0/-6mm,+6/-18mm and +18/- 50mm, with known quantities of test nuggets introduced into the samples commensurate with each size fraction to test recovery effectiveness.
Outstanding results were achieved for all Egina size fractions, (please refer to summarytable below) with 100% of gold recovered in 1.2% of the mass of the +18/-50mm size fraction, 100% of gold recovered in 0.3% of the mass of the +6/-18mmsize fraction and 92% (by weight) of gold recovered in 0.1% of the mass of +0/-6mmsize fraction. To better test recovery of the +0/-6mm size fraction, bulk material was delivered to TOMRA's laboratory in Wedel, Germany for testing on a new prototype fines sorting machine (please refer to "Wedel, Germany" summary below).
