Russia, 1859

Where 1 Poud (= 3,840 Zolotnik) = 2,941 руб Kr. (1859) and 1 English Troy Ounce = 7.2914432 Zolotnik, the Funt (presumed by 'fine,' by Specific Gravity 21.5) cost £ 10.19 - £ 10.65 at prevailing exchange.  Poud rates were for un-worked ore, at assumed Fine rates.*

1857: The cost of '1 kg platina' (@SG 21.5) 181.77 руб Kr. + Assumed Refining Cost (35 руб Kr.) = ~217 руб Kr./kg. (+ Duties?) = 6.75 руб/Ozt. (~ -30% lower than the 1828 Price)

*At SG 20, a 'kilogram of raw, assumed platinum' in ore sold much much lower; actual mass of the raw platina varied considerably, containing other PGMs.  For example, worked ingot Platinum was assumed 21.35 in 1835. If Ural platina was just 81.5% those metals (Pt, Ir, Au) to that SG, or ~ 80% - 80.5% pure Pt.  So ore merchants must have adjusted accordingly: to produce 1 kg. Pt @ .999 actually required ~1.25 Kg of Ural Ore (.805 Fine Pt).

Die Kosten für die zu errichtende Platinraffinerie würden sich leicht aus dem Preise für Platin decken, indem Rub. 1000 von jedem verkauften Pud Platin dazu bestimmt werden, was im ersten Jahre Rub. 200,000-260,000 ausmachen würde. Im Auslande zahlt man pro 1 Pud raffiniertes Platin Rub. 17,760, während das Rohplatin Rub. 7,300 kostet. Das Raffiniren eines Pudes kostet Rub. 425; rechnet man noch dazu die Ausgaben für Verbesserung an den technischen Einrichtungen und Verwaltung 50 Proc. der obigen Summe, so würden zu der Zeit, wo der Preis auf Rohplatin Rub. 7300 pro Pud betrug, für den Ankauf von Rohplatin 17,760 - (425 + 212), mithin Rub. 17,123 verfügbar bleiben und die Productionskosten für 1 Jahr bei einer Verarbeitung von 200-250 Pud jährlich Rub. 127,000 — 159,000 betragen.

 In 1877, the price rose to Rub. 2400, because the offer was low, and the buyer feared competition. This is still very low price made it possible to only exploit the platinum richest localities on the Issa, and consequently this was also a year to a very limited yield, 1867-1869 6-7 Poud, 1870-1877.  The cost of the platinum refinery to be built would easily be covered by profit on the price of Platinum,  determined at Rub. 1,000. per Poud, which in the first year would amount to Rub. 200,000. to 260,000.  Abroad, you pay Rub. 17,760. per Poud refined platinum, while the crude platina costs Rub. 7,300.   The refining of a Poud costs Rub. 425; we still expect expenditure on improvement of technical devices and management to be 50% of the above sum, so when the price of crude platinum was Rub. 7,300 per Poud, for the purchase of crude platinum 17,760 - (425 + 212), thus Rub. 17,123 remain available and the annual cost of production for processing 200-250 poods annually would be Rub. 127,000-159,000.
