Abstract:
A low-flux converting process for PGM collector alloy. The process includes feed introduction into a molten alloy pool, oxygen injection into the pool, tapping the slag, and tapping the PGM-enriched alloy. The collector alloy contains no less than 0.5 wt % PGM, 40 wt % iron, and 0.5 wt % nickel. If added flux material contains more than 10 wt % silica and 10 wt % CaO/MgO, the feed contains no more than 20 parts by weight added flux per hundred collector alloy. The process can also include using a refractory protectant in the converter; melting partially pre-oxidized collector alloy to form the initial molten alloy pool; magnetic separation of slag; recycling part of the slag to the converter; smelting catalyst material in a primary furnace to produce the collector alloy; and/or smelting the converter slag in a secondary furnace with slag from the primary furnace.

Claim (Index 30):
The process of  claim 29 , wherein the collector alloy comprises: from 0.5 to 12 wt % PGM; no less than 40 wt % iron, preferably 40 to 80 wt % iron; no less than 0.5 wt % nickel, preferably 1 to 15 wt % nickel; no more than 3 wt % sulfur, preferably no less than 0.1 wt % sulfur; preferably no more than 3 wt % copper, more preferably 0.1 to 3 wt % copper; and preferably no more than 20 wt % silicon, more preferably 1 to 20 wt % silicon; and/or wherein the PGM-enriched alloy comprises: no less than 25 wt % PGM, preferably from 25 to 60 wt % PGM; no less than 25 wt % nickel, preferably from 25 to 70 wt % nickel; and preferably no more than 2 wt % silicon, no more than 2 wt % phosphorus, no more than 10 wt % copper, and no more than 2 wt % sulfur.
