Key Learning Objectives
- Appreciate the formation of iron ores and how this determines their properties
- Understand the impact of impurities on downstream users and understand why some ores are sellable and some are not
- Explain the chemical and physical properties of ores that customers need
- Review the major types of iron ore and their characteristics which allow them to be upgraded
- Examine the major methods of upgrading hematite and magnetite ores
- Compare the likely capital and operating costs of each upgrading process
- Review the factors which might lead to a successful project
- Compare practical processing projects from around the world
About the Course
The users of iron ore have a number of specific characteristics they are looking for. This means that while iron ore is a bulk commodity, the market for some ores is very limited.
The course is designed to explain what the users of iron ore are looking for in both physical and chemical properties and how processing the ore can create the necessary properties.
Participants will look at the typical types of iron ore deposits and how each may be processed to achieve a sellable product. It will also outline the process routes to treat both hematite and magnetite and demonstrate the benefits of each type of material.
There will be a particular emphasis on magnetite, which almost always needs processing to reach a satisfactory grade, and test work programs that need to be developed for each type of ore and how they impact on the design will also be covered.
The course will highlight the major capital and operating cost factors for each processing route and indicate the type of features that will be needed for a successful project.
Who Will Benefit
The course is designed for people who need to understand which features of an iron ore body are important from a processing and end user point of view.
Geologists, mineral process engineers, managers and directors of project development companies, design engineers moving into a mineral processing field and other technical personnel planning to enter the iron ore industry. Finance personnel being asked to fund projects and new mining industry graduates will also find this beneficial, however some understanding of basic mineral processing is recommended.
