Problems solved by technology

However, since the main factors affecting hydraulic settlement are particle size and particle density, for mineral particles with small density differences, the average density can be used to calculate the sedimentation velocity of mineral particles; When grading by the method, the mineral particles with large particles and small density and small particles with high density have the same sedimentation velocity, and the obtained classified products are not classified according to the size of mineral particles, which will affect the metal distribution results.

Abstract

A method for determining the particle size composition and metal distribution of fine-grained mineral materials. The steps are: sequentially measure the true density of fine-grained mineral materials, useful minerals, and gangue minerals; use a continuous water separator to classify the mineral materials, and the classification is completed. Afterwards, the mineral materials in each classification chamber of the continuous water analyzer are weighed and tested to obtain the yield of mineral materials in each classification chamber and the grade of useful metal elements or metal compounds in the mineral materials, and then calculate the mineral materials in each classification chamber of the continuous water analyzer. The yield of useful minerals and gangue minerals; determine the sedimentation particle size of useful minerals and gangue minerals in each classification chamber according to the Stokes particle sedimentation formula; establish the relationship between the sedimentation particle size and cumulative yield of useful minerals and gangue minerals in each classification chamber. , use the established relational expressions to calculate the yield of mineral materials, useful minerals and gangue minerals of each particle size, and obtain the metal distribution rate of mineral materials, thereby determining the particle size composition and metal distribution of mineral materials.
