fluxes for smelting platinum

Recovery of platinum-group metals from spent catalysts by ...

The feasibility of a facile route to recover platinum-group metals (PGMs) from spent catalyst by microwave smelting of spent catalyst with the additions of nickel matte as metal collector and sodium salts as fluxes was verified, based on the thermodynamic and experimental analyses which evaluated the dielectric properties, conductivities ...

Optimal Metallurgical Flux Recipe for Primary Refining of ...

We use the Zadra strip/EW process to produce gold sludge, which is then sent to our furnace, after drying, to be refined. I was curious to know how one would determine the best flux recipe (constituents/amounts) for primary refining. Additionally, what are some control strategies to …

Induction Melting of Platinum with UltraMelt 5P | UltraFlex

Application Note Objective: The objective is to melt platinum with UltraMelt 5P induction melting furnace for the production of platinum bars.. Equipment: Platinum is a challenging metal to melt due to its high melting temperature, but with UltraMelt 5P this can be done quickly, easily, and efficiently. The system can also be used for the melting of most precious and non-precious metals and ...

(PDF) Metals smelting-collection method for recycling of ...

Experimental results indicated that the maximum platinum recovery was over 98%, when cordierite carrier WAC addition, collector metal addition, CaO/SiO2 mass ratio, smelting temperature, and ...

SMELTING SILVER

Fluxes I have decided to explain those things which mining people call fluxes because they are added to ores not only for assaying, but also for smelting. (Agricola, p. 232) All silver ores need to be fluxed for smelting.6 In Pliny's day, when almost all the ore smelted was high-grade, the addition of lead or lead ore (galena, PbS) was

Platinum Melting Furnace, Gold/Silver/Platinum Induction ...

SuperbMelt platinum melting furnace (SPB-B) is a totally ingenious technological creation which is designed with the aim of providing superior melting action on precious metals like platinum, gold, palladium or alloys of these metals. This platinum smelting furnace can reach a temperature of about 2600℃ (It is about 900℃ higher than the ...

How to Choose Gold Smelting Flux

The smelting thus commences. How do the Fluxes react during the process? For a flux mixture containing Litharge, around 550oC, the litharge is reduced to lead by the action of reducing agents ...

Extraction and Refining of the Platinum Metals | Johnson ...

A major development in the world's platinum industry took place in the early nineteen twenties when large deposits of platinum bearing ore were discovered in the Transvaal in South Africa. This led to the formation in 1931 of Rustenburg Platinum Mines Limited to work these deposits, and this company remains to this day the only platinum producer in South Africa and the only major producer in ...

Buying fluxes | Gold Refining & Metal Extraction Forum

I got a small amount (5 or 6 ounces) through Amazon. It was granulated to a very fine powder. For the same cost, I was able to get a 65 oz. box of 20 Mule Team Borax at the hardware store.

Hank Chapman Refining Flux for Gold, Black Sands, Ore ...

A great pre-mixed refining flux containing Anhydrous Borax, Soda Ash and a bit of Silica Sand. Excellent for refining Gold and black sands! Use with our Chapman Flux Thinner for optimal results.

PLATINUM FLUX SMELTING PLATINUM | TreasureNet 🧭 The ...

Going to need some more info on what you have, and what you are trying to do before recommending any good flux for recovering platinum (Pt). Also, keep in mind the high melting point of Pt (1772C - 3222F), will require the flux mixture to have some sort of eutectic action (lowering the melting point) of the Pt if you are going to fire it in a ...

METALLURGICAL USES FLUXES FOR METALLURGY

FLUXES FOR METALLURGY HAROLD R. KOKAL AND MADHU G. RANADE A metallurgicalf2ux is a substance that is added to combine with gangue (unwanted minerals) during ore smelting, with impurities in a molten metal, or with other additives in metal refining processes to form a slag that can be separated from the metal. Because slags

Melting the Platinum Group Metals | Johnson Matthey ...

Before 1782 little more than a 'partial agglomeration' of platinum had been achieved, mainly by hot forging from the powder which, although it sufficed to make many platinum artefacts, did not produce homogeneous molten metal ().The first to melt impure platinum may have been Henrik Theophil Scheffer (1710–1759) who in 1751 melted platinum with copper, and later arsenic, in a furnace ().
