The Fundamentals of Mineral Base Oil Refining
Refining is performed to remove unwanted chemical structures (rings, etc.) from the base oil to reduce the tendency of the base oil to age in service and also to improve the viscosity/temperature characteristics. Three basic refining processes are used by oil companies: (a) Sulphuric acid/clay refining (old, outdated technology)
WhatsAppMethods for Separating Mixtures | Chemistry for NonMajors
Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.
Introduction to Mineral Processing Chevron Phillips Chemical
Frothers are liquids that produce the froth or on which the flotation process depends. The froth resembles soap suds and provides the physical separation between the mineral(s) floated and the pulp containing the waste. The froth must be strong enough to support the weight of the mineral floated and yet not be tenacious and nonflowing.
Concentration and dressing of the ore, Physical Methods ...
By magnetic separation method the nonmagnetic minerals is separated from the magnetic mineral. For example tinstone or cassiterite, SnO 2 (nonmagnetic) containing wolfram, FeWO 4 (magnetic) is separated by this method. In this method a thin layer of finely ground ore is spread over a rubber belt carried over a pulley in a magnetic field.

Physical separation steps are often used before chemical extraction to grade the soil into coarse and fine fractions, with the assumption that the fines contain most of the contamination. Physical separation can also enhance the kinetics of extraction by separating out particulate heavy metals, if .
Separating Mixtures | Physical Separation ... Chemistry
The Separation process is used to transform a mixture of substances into distinct products. Mixtures are the product of mechanical blending of chemical substances such as elements and compounds, without formation of any chemical bond or change in the individual components, so that each constituent can retain its original state. Even though there are no chemical changes to the mixture, some alteration is .
