AGtrition - Conceptual design for developing a multidimensional small-scale AG mill test

Purpose and goal: ** Denna text är maskinöversatt **

Aim of the feasibility study was to investigate the different loading mechanisms involved in autogenous grinding and their effect on grinding performance by exploring different test methods and, based on that, derive a conceptual design to develop a multidimensional small-scale test method that takes into account (i) variability within the ore body and (ii) relevant aspects of comminution in autogen mills.

Expected results and effects: ** Denna text är maskinöversatt ** The following results have come out of the project:

- A mineralogical characterization of selected ore samples as a basis for correlating fracture parameters to mineralogical parameters - Examination of different test protocols based on previous review and experience and supplemented with lab tests - Prerequisites for the development of a multidimensional, small-scale AG- Test.

Approach and implementation: ** Denna text är maskinöversatt ** The project (pre-study) is organized in three work packages: WP1 Projektkoordination: Project planning and reporting

WP2 AG-testutvärdering: Sampling, characterization of selected ore samples, analysis of results from previous AG tests, execution of fragmentation tests and tests to investigate fatigue of the material.

WP3 Konceptdesign: Analysis of autogen mill parameters, investigation of possible correlations between the AG test results of different samples and mill parameters, development of ideas for a new small-scale AG test.
