The refining process also rearranges the structures and bonding patterns of the basic molecules into different, more desirable hydrocarbon molecules and compounds. The type of hydrocarbon (paraffinic, naphthenic or aromatic) rather than the specific chemical compounds present, is the most significant factor in the refining process.

Palladium (Pd) refining can be a daunting task, similar to the other Platinum group metals (PGM's) refining process. This is mainly due to their similar (but different) physical and chemical properties. Separating Palladium from base metals and especially from sister PGM's, is rarely achieved completely in one refining cycle.

We perfected this process back in the late 80s for other refiners to refine both gold and platinum group metals safely, while also reducing costs. ... General consensus is that dissolving base metals with gold will add steps to the refining process and consume more chemicals. When done ...
In the Refining Division: Gold refining process reduces the quantity of waste products generated per ounce recovered by 75%. A newly developed platinum and palladium refining process reduces the quantity of waste products generated per ounce recovered by 60%.
Because it skips this step, the HIsarna process is more energy-efficient and has a lower carbon footprint than traditional steelmaking processes. Refining. Refining consists of purifying an impure material, in this case a metal. In refining, the final material is usually chemically identical to the original, but purer.

The ﬁ st step to recover PGM metals and especially platinum from used auto catalytic converters is to col-lect and then dismantle them. After these operations catalytic converter carriers are milled and also homog-enized. Then chemical analysis must be performed in order to check the level of platinum and other precious metals.

Platinum Refining Process is described below. Platinum refineries provide an economical and environmentally friendly precious metal recovery service. We buy platinum scrap and separate the pure platinum from other precious metals and waste materials.
The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.
Saltwater-based refining. This process is excellent for silver and platinum group metals. Silver is recoverable using this process, but unfortunately, it will not refine the silver.
