Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. . However, because the Bessel process was used on graphite not gold, silver, copper, lead, zinc, etc . The generally recognized first successful commercial flotation process for mineral sulphides was invented by Frank Elmore who.
When properly characterised, sulphide complex gold ores can be efficiently . coarse sulphide gold ores include the Python plant and the Gravity Flotation . amount of gold that can be recovered by further processing using equipment such as.
