The unwanted waste rock gangue falls to the bottom and is removed. The froth is skimmed off the surface and the enriched ore mainly the copper mineral is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25 copper by mass and is called copper concentrate.

The platinum will precipitate as a red mud. if you want to leave the iridium in the platinum, then wait for it to precipitate before recovering the platinum. iridium will precipitate as a blue-black mud after the platinum precipitates. platinum group metals will also show up on the stannous chloride test. platinum turns red, palladium.
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.
Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

Platinum-group metals are found mainly in south africa and russia, and are mostly also produced in those countries. extraction of platinum-group metals consists of the following steps mining, concentration, smeltingconverting, leaching and refining to metal. about 500 tonnes of platinum-group metals are produced per year.

An effectual technique is for a miner to employ a slusher, which is an electric appliance with a 48-inch scraper container to take away ore from a stope. the bucket is fitted to a cable affixed to the visage of the stope. the mechanism is situated at the rear of the ore chute and draws the container forward, staging it with ore.

How can i extract platinum group metals from cu based rock imagine that i have a copper based ore which also consists platinum group metals. pt , pd, au, ag are the elements in my cu based ore.
When we talk about reclaiming the hidden value in your platinum scrap, theres no more profitable precious metal to recycle and refine than platinum and when it comes to finding the best platinum refiners, you dont have to look any further than specialty metals smelters and refiners, the top choice for secondary refining of platinum in the u ...
The steps that constitute the process are leaching with sulphuric acid and nitric acid, removal of impurities, precipitation of palladium yellow salt dichlorediamine-palladium ii, reduction of this salt to metallic palladium and finally the smelting of this metal.
Sep 19, 2014nbsp018332another method of separation is to bubble air through the mixture, so that the platinum ore grains not the platinum itself react with oxygen forming a slurry on the surface which can be skimmed off. drying and purification the wet platinum slurry is heated in specialist furnaces which maintain a temperature of 1500 degrees.
Cant say much except soft is bad unless have a nearly pure metal, maybe a sign of lead, silver or mercury. 5 with results 1-4, you can fill out a request to quote from a reputable company to whom you would mail the material, and receive payment after the assaying and refining costs are subtracted.
Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments. collect the filtered gold chloride solution in a flask. place powdered sodium metabisulfate in another flask and dissolve with water. this forms a solution of sodium bisulfate.

Since the identification of economic deposits of platinum in south africa in 1924 by hans merensky, a number of platinum mines have come and gone, and some have merely changed identity. 1-3 south africa currently has four integrated primary platinum producers, namely amplats 4,5 anglo american platinum corporation ltd, formerly rustenburg ...
Among these, palladium, gold and platinum have a high economic interest. the purpose of this work was the treatment of the solid residue produced from the iron dust precipitation, aiming to recover and refine the contained palladium.
Sep 19, 2014nbsp0183321. how is platinum extracted from its ore an ore is a naturally occurring mineral from which a pure metal can be extracted. for platinum, the two- chief minerals are sperrylite or platinum arsenide ptas2 and co-operate or platinum sulfide pts. extracting platinum from these ores is arguably one of the most capital and labour intensive ...

Aug 07, 2013nbsp018332in metal refining, a flux is sort of like a cleaning agent because it helps remove impurities from a sample. with some borax, heat, and a little know-how, its possible to extract pure gold from a sample of ore. this is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold.
