Comparing Test A to the baseline flotation studies reported earlier for the first 75 min (Fig 7a), Test A gives a better gold recovery (687%) at higher gold concentrate grade (67 g/t Au) The increase in gold recovery from 599% (p80=70 µm) to 687% (p80=38 µm) can be attributed to improved liberation of gold from pyrite at the finer grindPilot Gold Reports Gold Recoveries up to 95% at Kinsley Mountain Western Flank sulphide mineralization amenable to flotation processing with concentrate grades up to 312 g/t gold Pilot Gold Inc (PLG TSX) (“Pilot Gold” or the “Company”) is pleased to report results from an initialPilot Gold Reports Gold Recoveries up to 95% at Kinsley
The gold grade was 4944 g/t and the gold recovery was 3336% in the flotation concentrate, and the total recovery of gold was 9094% The main minerals in the flotation concentrate were pyrite and arsenopyrite, the total content of As, S, and Fe reached 8830%, and the further enrichment space of gold in the goldbearing mineral was limited byThe other flotation concentrate had much lesser gold grade (17 g/t) and, hence, produced a biooxidised product of 23 g/t gold grade Different proportions of minerals such as quartz, muscovite, illite, gypsum, albite, ephesite, bassanite, jarosite, larnite, rutile, chamosite, pyrite, apatite, goethite and arsenopyrite were observed in theUnravelling Causes of Refractoriness in Complex
A concentrate grade is the gold content in the concentrate and usually is expressed in grams per tonne (g/t) or ounces per tonne (oz/t) the ratio of concentration is the proportion of the weight of the feed to the weight of the concentrateGravity concentration and flotation testwork has been carried out on three composite samples from the Spanish Mountain Deposit in British Columbia The composites had a head gold grade varying from 045 to 094 g/t Au and represented different lithologies in the depositGRAVITY CONCENTRATION AND FLOTATION OF
