Cost of Secondary Processing

Cost incurred in secondary processing of earths, rocks and minerals not carried out at the extraction site (that is secondary processing such as bitumen coating of chippings); secondary processing of materials recovered by dredging once they have been transferred from the dredging vessel (including the transfer process); or mineral prospecting; secondary processing of crude oil into gases, liquids and solids or metalworking processes that follow the forging process in which case the typical secondary processes are heat treating, rough machining, trimming, torch cutting, and testing.
