  • (PDF) The Effect of Collector's Type on Gold and Silver

    Flotation has been applied on ores containing free gold and silver particles for many years. The flotation efficiency of gold and silver particles depends on the modifiers and collectors. This...

  • 17 Flotation of Gold Ores Aalto

    Flotation of Gold Ores 17.1 INTRODUCTION The recovery of gold from gold-bearing ores depends largely on the nature of the deposit, the mineralogy of the ore and the distribution of gold in the ore. The methods used for the recovery of gold consist of the following unit operations: 1. The gravity preconcentration method, which is used mainly for recovery of gold from placer deposits that

    Analyses of original ore showed that the sample contained 4.93 % Cu, 0.007 % Co, 0.92 % Zn, 11.41 % Fe, 10.72, % S, 4.72 g/t Au and 12.80 g/t Ag. It was determined that gold and silver could not be reached with satisfactory yields by flotation of original ore at the defined size. Thus, original ore was sulfurized before the flotation. By the

  • Recovery from complex ore by floatation CORE

    Beneficiation of complex lead and zinc ore was investigated using flotation method. Various parameters such as particle size, flotation stages, collector type, collector amount, control reagents were investigated to recover of gold and silver bearing minerals. At the end of the experimental studies, the flotation experiments performed with Aero 208 + Aerophine 3418 A (350 + 350 g/t) collectors

  • Characterization and recovery of gold associated with fine

    CHARACTERIZATION AND RECOVERY OF GOLD ASSOCIATED WITH FINE, ACTIVATED CARBON 297 Particles containing low concentrations of silver equivalent to those found in the ore were present. However, particles of electrum, virtually pure gold and pure silver were also found which are not present in the ore. The presence of

  • Froth flotation Wikipedia

    For froth flotation, an aqueous slurrry the ground ore is treated with the frothing agent. An example is sodium ethyl xanthate as a collector in the flotation of galena (lead sulfide) to separate it from sphalerite (zinc sulfide). The polar part of xanthate anion attaches to the ore particles and the non-polar hydrocarbon part forms a hydrophobic layer. The particles are brought to the water

    Promoter for gold, silver, copper and zinc sulphide ores. Stronger than sodium aerofloat. Aerofloat 208: A non-frothing water soluble dry aerofloat. 5-10% solution .01 to .10: Alone or in the combination with reagent 301 is widely used for flotation of gold and silver. Aerofloat 211: A water soluble dry aerofloat. Formerly sodium aerofloat B. 5-10% solution .05 to .20 Same as sodium aerofloat

  • Mineral Processing Operating Cost Estimate of Ore

    In 1936 when data were being compiled for “Cyanidation and Concentration of Gold and Silver Ores,” considerable published information was available on milling costs in various parts of the world. At the present time, however, it is extremely difficult to obtain reliable figures on the cost of ore treatment owing to the fact that during a period of rising prices and wages the mine
