In many gold mines exploited during the gold rushes of the 19th century vein material alone was typically sought as ore material In most of today s mines ore material is primarily composed of the veins and some component of the wall rocks which surrounds the veinsGold Ore is basically gold as a mineral mixed with other sediment and minerals In order to turn that gold ore into gold you need to process that ore There are a few different ways to process that and neither interest me at this time
Jun 08 32 One is a nice silver ore specimen another zinc veszelyite quartz crystal formation and a few others I ll be learning gold prospecting and hopefully will have some time to make a few how to The old style method was in practice during past for single vein type deposit like gold bearing quartz veins of Kolar and Hutti Karnataka India and gold mines in South Africa The auriferous veins are usually either exposed or close to the surface
The largest gold quartz vein deposit in British Columbia is the Bralorne Pioneer which produced in excess of 117 800 kilograms of Au from ore with an average grade of 93 g/t ECONOMIC LIMITATIONS These veins are usually less than 2m wide and therefore only amenable to underground miningCharacteristics of Gold Bearing Quartz Veins Part 1 Iron stained or rusty quartz like this is a common gold bearing vein material The single most common gold bearing matrix in the world as a Gold Ore Rock Crusher Impact Flail Processing Quartz
Quartz veins often fluctuate widely in value with the richest gold ore occurring in pockets or “bonanzas” as they are sometimes called In some mining districts the bulk of the gold is found in these rich pockets and the rest of the vein may be nearly barrenOr the value may be in minerals like gold silver copper and other ores scattered through quartz calcite or other mineral forming the main part of the vein matter the gangue The material deposited in veins etc was forced upwards through and into weak places in the rocks taking the path of least resistance rather than through the more
The quartz precipitation is followed by gold precipitation results in banded veins with each band representing a different phase in the process Low sulphidation systems typically show a lateral zoning from proximal quartz chalcedony adularia in mineralized veins which commonly display crustiform colloform banding and platy lattice quartz vein gold ore process equipment by cyanide leaching Hard Rock Gold Mining Wholesale Gold Mining Suppliers ISO approved High Quality hard rock mining equipment for gold production
Ore types Placer Gold Quartz Vein Gold Ores Oxidised Gold Ores Gold Silver Rich ores The gold generally occurs as liberated due to oxidation and alteration of sulphide minerals due to chemical action or native gold occurring in quartz veins or as electrum in silver rich or The major characteristic is the gold is easily liberatedORE FORMING FLUIDS IN ARCHEAN GOLD BEARING QUARTZ VEINS AT THE SIGMA MINE ABITIBI GREENSTONE BELT QUEBEC CANADAby Robert Francois Kelly William C Seer Secrets Gold Ore Gemstone Bath Bar │Made with Real Gemstone Corundum│ Packed with minerals │NO Chemicals │With Cherry Blossom extract Real Gold Leaf powder Quartz
A vein of coal and a vein of iron both in a ravine Ores like this can be hard to get to due to the difficulty of climbing the ravine s wall Exposed ore veinsA reef is another term for a vein of some mineral or ore and has nothing to do with biological reefs such as coral reefs Quartz is one of the most common minerals in the earth s crust and most quartz veins do not carry gold but those that have gold are avidly hunted by prospectors
