  • Oxidative pre-treatment in thiosulphate

    The pre-oxidised sulphide ores will be more amenable to the ammoniacal thiosulphate leaching with higher gold recoveries and less thiosulphate consumption. The sulphide ore of 400 g was pre-oxidised for different times in 1 L ammoniacal solutions with 0.8 M ammonia and 6 mM copper. The slurry was oxidised for 1, 3, 7 and 22 h, respectively. After the pre-oxidation, the slurry pH was adjusted

  • Sulphide Mineral Indicators For Gold – BC Gold

    Sulphide Mineral Indicators For Gold. Sulfide minerals can provide important clues for small-scale gold miners and prospectors in locating both placer and lode deposits. This is especially true when it comes to lode or vein gold. The following are some of the main sulfide mineral indicators you should keep an eye out for when prospecting. Bear in mind, mineral indicators are only clues that

  • Sulfides, Selenides and Tellurides: rebellious

    Sulfide ore from Austin that didn't contain at least 70 ounces per ton of silver had to go out on the dumps, because it was unprofitable to ship to the mill!

    Ore genesis - Wikipedia. Ore deposits formed by lateral secretion are formed by metamorphic reactions during shearing, which liberate mineral constituents such as quartz, sulfides, gold, carbonates, and oxides from deforming rocks, and focus these constituents into zones of reduced pressure or dilation such as faults This may occur without much hydrothermal fluid flow.

  • How Is Gold Purified? | Sciencing

    If the gold is a low grade ore, then it is broken up into chunks that are then put in carefully lined pads and treated with a dilute cyanide solution, which dissolves the gold. For high grade ore, the metal is sent to a grinding mill and made into a powder. Refractory ore contains carbon and is heated to over 1000 degrees F, which removes sulfide and carbon. The resulting oxide ore is directed

  • Small Scale Treatment of PM Sulfide Ores - Gold

    15.02.2020· The ore has a 5 to 10 percent sulfide content, so I expect about 10 to 20 pounds of sulfide concentrate. Dealing with 10 to 20 pounds is a lot easier than 200 pounds. There will be some loss of values in this operation - but I accept this because although the method is less than optimal, it's the best I can put together.
