The early day miners feared it, and it happened a lot more often than they would have liked: the easily worked rich surface ores they discovered on the surface gave way as they mined downward, to a vein full of sulfides, base metals and other nasty, rebellious and refractory ores.
Provided is a method for processing a gold-bearing sulfide ore which involves maintaining the ore in a substantially oxygen free environment, preferably beginning with comminution of the ore and ending when a desired final concentrate, enriched in sulfide minerals, is obtained by flotation. In one embodiment, nitrogen gas is used to substantially prevent contact between the ore and air during ...

GOLD FLOTATION The flotation process, which is today so extensively used for the concentration of base-metal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a .
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. ...

Xinhai provides mineral processing technology, equipment manufacture and one-stop service for mineral processing plant, which solve many problems for mine investors. Xinhai equipment mainly include: ball mills, flotation, thickeners, and so on.
separation, flotation, solvent extraction, electrowinning, leaching, precipitation, and amalgamation (often involving the use of mercury). Wastes from these processes include waste rock dumps, tailings, heap leach materials (for gold and silver operations), and dump leach materials (for copper leach operations).

Posted by Matrix on 1st November 2011 If native gold is present, dithiophosphates can be used which are less selective to iron sulphides.
Other turnkey modular systems for pre-concentrating coarse sulphide-gold ores include the Python plant and the Gravity Flotation Intensive Leach (GFIL) systems, both of which incorporate the InLine Pressure Jig. Regrinding of pre-concentrated non-refractory sulphide complex gold material, by a conventional regrind mill, can produce free gold ...
Gold: The mineral native Gold information and pictures. Gold in its natural mineral form almost always has traces of silver, and may also contain traces of copper and iron. A Gold nugget is usually 70 to 95 percent gold, and the remainder mostly silver.
