Polystyrene | ExxonMobil white oils

Primol™ 542 is a 100 cST white oil and is ideal for polystyrene applications with low-transparency requirements. It offers an exceptionally outstanding low volatility, but, due to its high molecular weight, it is best used in grades at relatively low oil content to maintain transparency for general-purpose polystyrene grades.*

from its ores. The Coal Gold Agglomeration (CGA) process was developed some years ago and has the advantage in that gold is recovered by a procedure which has little or no negative impact on the environment. A gold ore containing liberated gold particles is contacted with coal-oil agglomerates, whereby the gold is recovered into the coal/oil phase.
