AI Technical Summary

Technical Problem

The existing gravity separation process ignores the influence of ore density on the test, resulting in an unreasonable density distribution of the test samples, which increases the difficulty of separation or causes unstable test conditions. This makes it impossible to accurately reflect industrial conditions and loses its test guidance value.

Method used

A laboratory gravity separation process based on grade and density constraints was adopted. By determining the threshold values ​​of the dual constraints, including the gold grade range, the upper limit of sulfur content, the average density range of the mixed sample, and the proportion range of carrier mineral content, density constraint verification and scheme optimization were carried out to ensure that the mixed ore sample has a stable density-based stratification ability in the gravity separation equipment.

Benefits of technology

This improves the accuracy and reliability of gravity separation tests, ensuring that test results more accurately reflect industrial operating conditions and providing reliable test data support for industrial-grade ore blending schemes and gravity separation process parameter adjustments.

Abstract

The application provides a laboratory gravity separation process ore blending method based on grade and density double constraints, and belongs to the technical field of mineral processing gravity separation sample ore blending. The method comprises sample collection, double constraint index threshold determination, ore blending scheme preliminary calculation, density constraint verification and scheme optimization, laboratory precise ore blending and calibration, and test effect feedback. The double constraint index threshold determination comprises a grade constraint threshold and a density constraint threshold. The grade constraint threshold comprises a gold grade interval and a sulfur content upper limit. The density constraint threshold comprises a mixed sample average density interval and a carrier mineral content proportion range. The method can optimize the density distribution and grade index of the test sample, adapt to the density separation core needs of the laboratory gravity separation process, and make the test data accurate and repeatable.
