Abstract

The invention discloses a method of quantitatively evaluating a beneficiation flowsheet optimization degree, which comprises the following steps: a sampling flow chart is drawn according to the process, and sampling positions and sampling requirements are determined according to needs; process sampling is carried out; sample analysis and study are carried out; process calculation is carried out; the relation between overall recovery and work recovery is determined; influences on the overall recovery by changes of the work recovery are analyzed; and the beneficiation flowsheet optimization degree is quantitatively evaluated. The quantitative mathematical relation between theoverall recovery and the unit work recovery is analyzed, the quantitative mathematical relation between changes of the overall recovery and sensitive factors of each unit work recovery is determined, and in combination with the process mineralogy study, the beneficiation flowsheet optimization degree is quantitatively evaluated, and an important guiding role can be played for beneficiation flowsheet optimization.

Description

technical field [0001] The invention relates to the technical field of beneficiation technology, and relates to a method for quantitatively evaluating the degree of optimization of a beneficiation process. Background technique [0002] Concentrators should regularly and irregularly conduct partial and complete process investigations on production status, technical conditions, technical indicators, equipment performance and working conditions, properties of raw materials, whereabouts of metal loss and related parameters, that is, process inspections. [0003] The process inspection analyzes and calculates the technological process and original data, draws the flow chart of the number and quality of ore dressing and the flow chart of the pulp, and compiles the three analysis (screen analysis, water analysis, mirror analysis) tables, metal balance tables, water balance tables, etc. Process inspection usually lacks quantitative evaluation on the theoretical total recovery rate a...
