Successful Pilot Tests on Tailings Re-Treatment & Results of Special Meeting of Shareholders
23rd January 2014 : Galantas Gold Corporation has today announced the results of positive test-work on tailings re-treatment and results of a Special Meeting of Shareholders.
Operations / Test-work.
During the fourth quarter of 2013, tests were carried out on tailings cells filled during the earlier operation of the mine. The results confirm pre-existing data that indicated the tailings contain between 0.5g/t gold and 1 g/t gold and meet European Union standards for definition as inert material.
A low energy cost processing solution, based upon a Knelson CD12 centrifugal gravity concentrator, which was already utilised in the gold processing plant in a secondary role, has been successfully pilot tested as a prime re-treatment component for flotation tailings. The tailings do not require comminution (crushing and grinding) for re-processing by this method. Concentrate grades produced by the pilot study were high, between 298 and 526 g/t Gold, with between 207 and 270 g/t Silver. This compares to grades for flotation concentrate from mined vein material of around 100 g/t gold. The higher concentrate grades have a higher financial reward from a smelter because a proportion of smelter charges are calculated on a tonnage basis and the lack of comminution required reduces energy and labour costs.
Secondary re-treatment, by froth flotation, of Knelson concentrate tailings, was also pilot tested but was found to produce a relatively low value product.
