Abstract: A MINERAL-OIL-BASED LUBRICANT FOR USE IN DRILLING OF MINERAL ORE DEPOSITS, WHICH IS NON-STAINING TOWARDS SAMPLE CORES WITHDRAWN DURING THE DRILLING, CAN BE PREPARED BY COMBINING A PARAFFINIC OIL, WITH MINOR AMOUNTS OF A NONIOMIC EMULSIFIER PACKAGE AND A SULFUR-CONTAINING EXTREME PRESSURE AGENT. THE NONIONIC EMULSIFIER PACKAGE CAN BE A COMBINATION OF AN ALKOXYLATED FATTY ACID ESTER AND AN ALKOXYLATED ALKYL PHENOL OR A COMBINATION OF FATTY ACID SORBITAN POLYESTERS WHICH HAVE BEEN ALKOXYLATED TO VARYING EXTENTS.
