• Silver Gold Recovery Flotation Process

    The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the basemetal minerals, if present, being of little or no value The first class

    01042014· A novel process was developed to markedly increase silver cyanidation performance from a refractory gold–silver ore in Beiya, Yunnan province, China Before cyanidation, the process employs a pretreatment step that aims at liberating the silver grains by destroying the crystal lattices of manganese minerals The pretreatment step could be described as a reductive sulfating leaching technology to

  • Silver ores Danafloat

    The most common silverbearing minerals recovered by flotation are argentiferous galena, native silver, argentite (Ag2S) and tetrahedrite (Cu,Fe,Ag) Sb4S3) Often these minerals float with the base metals such as copper and lead sulphides or are the primary target mineral (tetrahedrite) Aryl (cresylic or phenyl based) and alkyl based dithiophosphates enhance the recovery of free silver
