Refinery Economics - NRCan

Refinery Economics. The overall economics or viability of a refinery depends on the interaction of three key elements: the choice of crude oil used (crude slates), the complexity of the refining equipment (refinery configuration) and the desired type and quality of products produced (product slate). Refinery utilization rates and environmental ...

The Fundamentals of Mineral Base Oil Refining

2021/8/11· The cost of refining oil using the conversion process is somewhat higher than the extraction process. This extra cost incurred by the refiner is eventually passed on to the customer. However, in this case, the customer typically gets what he pays for - a higher quality base oil at a higher initial price.

Ore Treatment - an overview | ScienceDirect Topics

Mineral processing comprises many unit operations, such as gravity concentration, magnetic concentration and flotation, which are all aimed at extracting valuable material from ores. Usually, the process operation conditions are defined to control the balance between a high recovery of the desired metal and a high grade value of the metal in the product outflow ( Méndez et al., 2009a ).
