「ore dressing separating metals from ores」
Ore processing or ore dressing is the separation of iron ore from gangue in order to optimize the blast furnace process! In principle, the undesirable gangue can never be completely separated from the iron ores during ore dressing. This means that a certain amount of unwanted elements always enters the blast furnace process. Inquire Now
Gold Extraction & Recovery Processes
29-02-2016· Changes in ore properties, such as ore gold distribution and hardness have influence in gold liberation and consequently will be affected the recovery process. For example, orebodies containing clays have problems due to the excessive amount of fine material liberated during the comminution process due to rheological and physiochemical properties are modified.
