Filtang conducts relatively systematic laboratory tests, semi-industrial tests and theoretical analysis and calculations, and determines reasonable technical experimental plans based on the process methods adopted according to technical conditions, and determines the process route based on the experimental results.

The selection of filtration equipment can be determined through laboratory tests and semi-industrial tests, and the washing and conveying methods of the slurry can be determined based on the viscosity parameter measurement and conveying performance analysis and calculation. The main tests and calculations are material particle size analysis and basic physical and chemical parameter measurement, reagent ratio optimization test, viscosity parameter measurement and conveying performance analysis.
