3 Ways to Identify Gold in Quartz wikiHow

26/03/2018· If you find gold in quartz in nature, use a geology hammer and sledge to break open the quartz and potential gold bearing rocks. Be sure you have permission from the land owner to remove rocks from the property before doing this. Don't trespass on land without written permission by the owner. 3. Use a metal detector if you have one. Larger gold pieces will give off a strong signal on a metal

Eight Natural Geologic Signs Pointing Toward Gold

Iron Staining & Gossans: Not all veins produce much quartz gold bearing veins can consist of calcite or mostly sulfides which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators. Quartz Vein Matter Accumulations: At times, small accumulations of quartz vein

Chemical and Mineralogical Studies of Gold-bearing Rock

04/05/2019· This paper provides chemical and mineralogical studies on Gold-bearing rock ore. The samples used was sourced from Iperindo at Ilesha Local Government Area of Osun state, Nigeria. 500g of the ore was weighed using digital weighing balance. The samples were crushed and ground until 80% passing of 75 μm sieve. The ground ore was blended homogeneously before the analysis while for the

Geochemical prospecting for gold in the area north of

01/01/1987· Mineralization comprises gold/sulphide-bearing quartz veins and amphibolites. Data obtained from the stream sediment survey were subjected to statistical interpretation and it was found that the log-normal pattern appears to be the one most applicable to the element distributions. No indicator for gold has been identified, but the significant correlation that exists between Pb/Cu and
