How to Recognize Hard Rock Gold Ores September 2017 by Chris Ralph I regularly get inquiries along the line of “Hey I found this rock and I think it might be gold ore How can I tell” Prospectors are always on the lookout for goldbearing rocks that may be the source of any nearby placer gold
That would make the gold in a one pound ore sample worth approximately 75 cents and this is assuming that the ore is extremely rich Many mines can run profitably on much lower grade ores which might easily reduce the average value of ore down to 25 cents or less per pound
Dec 07 2012 · I have raw gold ore in rock form possible mixed in with quartz It is 78 grams and definitely has a good amount of gold I was wondering the average value for something like this and where to sell it Thanks best answer will be given
Jul 01 2011 · The salinity and temperature of oreforming fluids have wide ranges Salinities of some oreforming fluids are lower than sea water whereas those in fluids forming porphyry deposits can reach 80 wt NaCl Heinrich 2007The salinity and temperature of most hydrothermal fluid decrease during the latestages of ore formation suggesting either the attenuation of heat and fluid source or the
Srdjan M Bulatovic in Handbook of Flotation Reagents Chemistry Theory and Practice 2010 1710 Flotation of Arsenical Gold Ores There are two major groups of arsenical gold ores of economical value These are the massive base metal sulphides with arsenical gold ie the lead–zinc Olympias deposit Greece and arsenical gold ores without the presence of base metals
Many ores that contain gold contain other metallic metals in them also so there are likely to be a lot of shiny minerals mixed into the rock which may or may not be valuable The other challenge in visual inspecting gold ores for possible gold content is the fact that the total concentration of gold in a piece of ore is generally negligible
When you mix the finely powdered goldbearing rock with some mercury the gold within the rock dissolves and forms whats called a gold amalgam while the rest of the rock is left behind
