gold platinum and iron quartz beach sand dry concentrate

Oct 04 2019New stone and of course its an iron mineral I dont know why my fields have so many iron mineral stones but they are neat This one has what seems like quartz crystals on the outer shell and filling fissures Along with that there is heavy iron oxidization pieces of gold flakes and silver fla Joining together these units make possible to develop an appropriate flowsheet whose objective is to recover gold and the precious metals present in the ore Perhaps one of the greatest challenges in the gold mining industry is to produce high grade concentrates consistently at maximum recovery from the mineralized deposit

A GOLD

A GOLD-PLATINUM-PALLADIUM LODE IN SOUTHERN NEVADA By ADOLPH KNOPF INTRODUCTION The discovery of platinum-bearing gold ore at the Boss mine in southern Nevada was brought to the attention of the Geological Survey by Mr F A Hale jr in September 1914 Some samples of the ore were submitted at the same time

In geology a placer deposit or placer is an accumulation of valuable minerals formed by gravity separation during sedimentary processes The name is from the Spanish word placer meaning alluvial sand Placer mining is an important source of gold and was the main technique used in the early years of many gold rushes including the California Gold Rush

The placer gold in this area originates from the existing mines prospects and erosion from gold bearing quartz veins stringers iron stain zones in schist and along contacts of schist diorite and granite The host rocks are Yavapai schist a dark diorite and a coarse grained granite

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

Jul 12 2018If you think about how much sand there is on the beach – there is actually a lot of gold out there! If you are talking about an areas spanning from Oregon to Alaska there is billions of dollars worth of gold scattered throughout the sand but scattered is the key word here Successful beach mining require patience

Jan 24 2015Gold Refining Forum Can you shock the iron sands (heat them up in an oven then drop them into cold water) to split them to get at internal gold or does that only work with quartz? Top to sluice the material through a beach box which is a wide sluice with a thin veneer of water designed to extract gold from beach sand tropical

May 08 2008I have access to a large amount of Black Sand' ore concentrate which has assays showing extremely large concentrations of Gold Platinum and Rhodium But many people say it is worthless because it is impossible to extract the precious metals from the junk (especially Iron) Can the precious metals be extracted at all? If they can be extracted can it be done profitably?

May 10 2018The J-M Reef ore body in Montana contains mostly copper and nickel with low platinum content as a byproduct Gravel deposits in Alberta Canada provide a placer source for platinum in certain rivers where it coincides with gold and other minerals Platinum flakes can be recovered through gravel washings shaking tables and other methods

The frustrating thing about black sand is that while it is relatively easy to separate the normal sand and gravel from the gold it much more difficult to separate the small sized gold from the black sand and other concentrates There are many methods to accomplish this job –

There's Gold in the Sand of California's Beaches

Over the years miners have used a wide variety of equipment to extract gold from the sand Each method had both strengths and weaknesses One plan for finding the gold was to go down on the beach and scrape up the iron-rich black sand usually found in layers which is most likely to contain gold

Examples magnetite (black mineral found in beach sand) diamond (found in beach sand in South Africa) and gold (found in river sediment which prospectors panned for) 5 BIOLOGICAL certain species of bacteria are able to extract sulfur from metallic sulfides or extract and fix metals into place

Sample 1 is modern dune sand collected 4 miles south of Atlantic Beach and 150 yards inland from the beach Sample 2 is from ancient dunes 10 miles west of Jacksonville Beach where the sand is being worked commercially The studies were made on a heavy mineral concentrate from the washing plant

The grade of a typical heavy mineral sand ore deposit is usually low Within the 21st century the lowest cut-off grades of heavy minerals as a total heavy mineral (THM) concentrate from the bulk sand in most ore deposits of this type is around 1% heavy minerals although several are higher grade

Beach placers of the Oregon coast By J T Pardee Abstract Beach placers along the Oregon coast were richly productive for a time after their discovery in 1852 and have since yielded small amounts of gold and platinum annually Renewed interest in then
