define Hydraulic washing and chromatography
Answers
Answer:
hydraulic washing – This separation is based on the difference in the specific gravities of the gangue particles and the ore particles are washed away.
Chromatography : - It is based on selective distribution of the various constituents of a mixture between two phases.
Answer:
Hydraulic washing : This method of concentration of ores is based on the differences in gravity is of the ore and the gangue particles. It is a type of gravity separation. An upward stream of running wateris used to wash the powdered ore. The lighter gangue particles are washed away and tge heavier ores are left behind.
Chromatography : chromatography is a physical method of separation of a mixture in which the components to be separated are distributed between two phase is stationary and mobile phase.
The stationary phase may be solid or liquid supported on a liquid or a gel the mobile phase may be either a liquid of a gas
