Ultra fine grinding of silver plant tailings of refractory ...

01/11/2013  Roasting [2], pressure oxidation [3], biooxidation [4,5] and ultra fine grinding [6] have been commercially practiced to enhance the gold/silver recoveries from refractory ores. The most common cause of refractoriness in gold and silver ores is the encapsulation of fine gold and silver particles within the mineral matrix in which these particles are not accessible to the lixiviating action of cyanide and

The Leachox™ Refractory Gold Process – The Testing, Design ...

Ultra Fine Grinding Often when gold is locked in sulphides and silicates it is necessary to reduce the particle size to a size where gold is liberated or partially liberated. For refractory ores this generally translates into grinding below 10 microns and often to as low as 3-4 microns.

Ultra fine grinding of silver plant tailings of refractory ...

01/11/2013  Ultra fine grinding of the plant tailings of a refractory silver ore was studied using a laboratory type vertical stirred media mill. Preliminary tests confirmed that ultra fine grinding substantially improves the extraction of silver from the tailings in cyanide leaching (i.e. 36% Ag extraction rate from the as-received tailings with d 80 of 100 μm, c.f. 84% extraction rate after ultra fine ...

The Leachox™ Process Maelgwyn Mineral Services

Grinding refractory gold ores to below 20 microns and finer, whilst liberating more gold, also liberates many other mineral species which affect the oxidative and cyanide downstream process. In many cases when only ultra fine grinding is used a maximum recovery is reached and grinding finer actually reduces the precious metal recovery. It also dramatically increases the reagent consumptions ...
