:: Getting a Handle on Wet Sticky Ores


Wet sticky ores present a handling issue due to the increase in its adhesive characteristics. This presents a particular problem for bulk handling and transport. P1095 - Characterisation and Design for Handling of Wet Sticky Ores AMIRA project is attempting to further understand these ore characteristics and prescribe ways of overcoming handling issues during bulk transport (i.e. conveyors, transfer chutes and the like). The project will deliver to Sponsors an in-field system for measuring the flowability of wet sticky ores and will also have evaluated options for on-line monitoring of adhesion.

The project will be executed by TUNRA Bulk Solids Handling Research Associates (TBS), a world leader in research and consulting advice in all aspects of storage, handling, conveying and transportation of bulk particulate materials. Established in 1975, TBS has worked with industry on over 4000 projects for more than 600 companies worldwide. TBS provides a combination of fundamental research, contract research and development and contract consulting to a wide range of clients in more than 40 countries worldwide.

The key deliverables from the project are:

  • A demonstrated prototype infield tool to quantitatively rank wet sticky ores for their flowability,
  • A recommendation for how adhesion build up can be monitored in materials handling equipment such as transfer chutes, storage bins and load out silo systems,
  • An enhanced laboratory capability for investigating flowability and adhesion phenomena associated with wet sticky ores,
  • Fundamental new insights about flowability and adhesion properties of wet sticky ores, the effect of vibration to promote flow within WSO handling systems, and enhanced mathematical modelling capability for future materials handling system design.

We invite you to join this exciting project, one that can aid your ability to handle wet sticky ores with confidence. And remember, where there is moisture, there is bound to be wet sticky ores.
