(a practical reason was the fact that the melting point of platinum is much higher than that of silver or gold; so high, in fact, that an oxygen flame is required for melting it. that is, a gold-melting furnace, using gas or coke with compressed air, is not hot enough to melt platinum. the fuel must be combined with oxygen oxygen such as is now.
A method of separating gold from palladium or at least one of gold and palladium from solutions containing the chloride complexes of at least the relevant ones of these metals together with other platinum group metals and wherein base metals may be present in the solution said method comprising contacting the solution for a sufficient length of time to result in extracting of substantially all.

Separation and purification of platinum group metals and gold nov 25, 1975 with reference to fig 1, a matte leach sludge containing all five pgms as well as gold is firstly treated in accordance with our co-pending patent application ser no 384,823 of even date entitled improvements in or relating to the separation and purification of.
Separation is concerned. an improved process which makes use of liquid-liquid extraction has been developed to a pilot plant stage, and this paper highlights some of the chemical and process principles that underlie this method of separation. the platinum group metals platinum, palladium, rhodium, iridium, osmium.
Separation of metals from nonmetals. magnetic separation can be further used to separate ferromagnetic from non-ferromagnetic metals. the target streams of stage 1, which would contain gold, silver, palladium, copper, zinc, tin, and other nonferrous metals will be further processed in stage 2 for recovery of valuable.
The selectivity of extraction of palladium(ii) over rhodium(iii) from 0.1 and 3 m hcl with p-c12 was the best. separation of palladium(ii) from platinum(iv) or gold(iii) is not so effective and it depends upon the acidity of aqueous.
This platinum was combined with the bulk of the palladium and gold as described hereinafter and separation of these pgms effected by a separate procedure. the residue/precipitate obtained from the initial aqua regia leach and sodium carbonate precipitation at stage 4 (+1400 g) was mixed with a flux a and a flux b defined below and fused at.
Tillet gave positive errors in the range of 0.3 to 1 per cent in the separation of platinum from the silver-gold-platinum alloy in which the platinum varied from 2.2 to 2.9 per cent . however, vauquelin did not report errors if the platinum content was less than 5 per cent ( 30 ); interestingly, the proportion of platina in the inquartation.
We demonstrate the separation of gold and silver nanoparticles according to their size and shape by agarose gel electrophoresis after coating them with a charged polymer layer. the separation is monitored optically using the size- and shape-dependent plasmon resonance of noble metal particles and confirmed by transmission electron microscopy (tem). electrophoretic mobilities are quantitatively.
