  • Photos of gold ores, quartz, telluride gold ore and gold

    Dry ore is the term often used. The second class of gold ores is auriferous copper ores. These are widely distributed throughout the United States and much of the chalcopyrite is gold bearing. These auriferous copper ores are especially abundant in Colorado, Utah, Montana and British Columbia.

    As expected, the copper in the circuit reduced to a low level, but when sulfide coppergold ore processing resumed, the copper concentration in the leach circuit did not attain previous levels even though a higher copper orebody was being mined. The copper recovery plant was operated intermittently for a few months and was eventually shut down.

  • POTENTIAL APPLICATIONS OF ORE PRE CONCENTRATION

    POTENTIAL APPLICATIONS OF ORE PRE CONCENTRATION USING HIGH VOLTAGE PULSES FOR AG/SAG MILLING ABSTRACT A novel technique using high voltage pulses (HVP) for ore pre concentration has recently been reported. The technique utilises metalliferous grain induced selective breakage and size based screening to separate the feed ore by grade.

  • What Does Gold Ore Look Like?Sciencing

    Apr 25, 2017· To the untrained eye, gold ore may look like rock with copper tones flowing within it. However, professional prospectors know how to recognize gold ore within a multitude of minerals. Recognizing the look and the location of gold ore is easier if you know how to find lode and placer deposits. General descriptions of

  • Iron oxide copper gold ore depositsWikipedia

    Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging

  • Eliminating Copper from Gold Ore

    When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper
