Large amounts of iron oxides like hematite magnetite and ironstone can be favorable indicators.

Rock Crushing methods and How to recover gold from Ores

Gold is often found associated with the mineral quartz. It is sometimes associated with other minerals as well including iron and manganese oxides calcite pyrite and other sulfides as well. It is not uncommon for prospectors especially those who operate metal detectors to find a rich gold bearing specimens of ore. Sometimes the best use of

Gold Jig Mineral Processing Jigs

The Gold Jig or Mineral Jigs are important of all types of alluvial gold concentrating device among all gravity separation methods they are also the most complex and the practice of jigging in mineral processing is often viewed as an art rather than a science. Gold jigging has been referred to as being probably the most complex gravity operation because of its continuously varying hydrodynamics.

Gold panning is mostly a manual technique of separating gold from other materials. Wide shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken sorting the gold from the gravel and other material. As gold is much denser than rock it quickly settles to the bottom of the pan.
