Placer mining for platinum has taken place intermittently in the area near Goodnews Bay in southwest Alaska since 1927 Recently a company called XS Platinum Limited was re processing the tailings left behind by past operations using earthmoving equipment and modern separation techniques The operation Platinum Creek Mine produced
Gold is typically extracted using various methods including placer mining hydraulic mining and heap leaching Once extracted gold ore is often processed through crushing grinding and chemical treatments such as cyanidation to separate the gold from the ore matrix Platinum mining and processing involve a complex journey from the
6 Using water to extract minerals is called placer mining This method is used to find valuable deposits of metals like gold and platinum that collect in stream beds
Placer deposits are masses of gravel or other residual or detrital material that contain one or more valuable minerals that have been concentrated by weathering and mechanical processes The concentrated minerals are therefore resistant to weathering and abrasion and are typically of greater specific gravity 22 than the most common minerals which have specific gravities
The underlying idea behind all placer mining processes is that gold is heavier than sand and rock Want placer gold contact us now Sell Gold 1 604 498 5001 [email protected] & Platinum Bullion at competitive and wholesale rates If you are looking to buy wholesale bullion Instant Gold Refining is the best place to buy bullion in
Platinum mining in Canada began after the metal was discovered in Ontario in 1888 amongnickel copper ores It can usually be found alongside other platinum group metals PGMs
Palladium Platinum Series Note that true native platinum in the mineralogical species sense is a rather rare mineral and most of the specimens so labelled are in fact isoferroplatinum or intimate mixtures of isoferroplatinum and tetraferroplatinum
Prospecting for placer gold except perhaps in the case of buried placers is the simplest form of prospecting Gold platinum and tin are the principal metallic minerals won from placers but gold alloyed with varying percentages of silver is the only metal that has been recovered in commercially important quantities from placers in the United States
Gold is typically extracted using various methods including placer mining hydraulic mining and heap leaching Once extracted gold ore is often processed through crushing grinding and chemical treatments such as cyanidation to separate the gold from the ore matrix Platinum mining and processing involve a complex journey from the
Placer mining evolved into vein and hard rock mining quartz gold mining and then into hydraulic mining in the mid to late nineteenth century Hydraulic mining employed water as the primary means of excavation The level of financial investment required for pit trench and underground mining was capital intensive and labor intensive as was
The alteration of platinum group minerals PGM of eluval proximal and distal placers associated with the Ural Alaskan type clinopyroxenite dunite massifs were studied The Isovsko Turinskaya placer system is unique regarding its size and was chosen as research object as it is PGM bearing for more than 70 km from its lode source the Ural Alaskan type Svetloborsky massif
The Platinum Creek Placer is located in Platinum Alaska and has been historically associated with the Goodnews Bay Mining District Its initial discovery can be attributed to Charles Thorsen in 1927 The Platinum Creek Placer has primarily been identified as a small scale producer

Eventually Goodnews Bay Mining Co consolidated the platinum producing claims in the area and operated a bucket line dredge in the area from 1937 to 1978 accounting for most of the roughly 650 000 oz of platinum that has been mined from the streams in this area Red Mountain is considered the likely source of the placer platinum deposits
