• The leaching and adsorption behaviour of gold ores

    There are many nonidealities in gold processing which are becoming increasingly important as simple freemilling oxide ores are depleted. During cyanidation and adsorption onto activated carbon, these effects include competing metalcyanide complexes, pregrobbing and the mineralogy of the ore. This thesis considers these areas from an experimental and modelling .

     · The traditional process for gold recovery from cyanide leach liquors has been the countercurrent decantation process. Following leaching, countercurrent decantation takes place in a series of thickeners in which the leach pulp is washed by the countercurrent flow of barren solution. The classified pregnant solution is treated for gold recovery with zinc dust. The precipitate may be acid ...

  • PHASES OF A MINING PROJECT

    The gold content of a good grade gold ore may be only a few onehundredths of a percent. Therefore, the next step in mining is grinding (or milling) the ore and separating the relatively small quantities of metal from the nonmetallic material of the ore in a process called 'beneficiation.' Milling is one of the most costly parts of beneficiation, and results in very fine .
